Cell Membrane (Plasma Membrane) [1]
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions
Another is that the membrane of the cell, which would be the plasma membrane, will have proteins on it which interact with other cells. Those proteins can be glycoproteins, meaning there’s a sugar and a protein moiety, or they could be lipid proteins, meaning that there’s a fat and a protein

Both types of membranes have a specialized structure that facilitates their gatekeeping function.. With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains
Within an individual glycerophospholipid, fatty acids are attached to the first and second carbons, and the phosphate group is attached to the third carbon of the glycerol backbone. Space-filling models of these molecules reveal their cylindrical shape, a geometry that allows glycerophospholipids to align side-by-side to form broad sheets (Figure 1).
Plant vs animal cells review (article) [3]
Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria.. However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs
Diagram of an animal cell with components lettered.. – Both animal and plant cells have mitochondria, but only plant cells have chloroplasts
This process (photosynthesis) takes place in the chloroplast. Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell

Cell membrane [6]
The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).[1][2] The cell membrane consists of a lipid bilayer, made up of two layers of phospholipids with cholesterols (a lipid component) interspersed between them, maintaining appropriate membrane fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that span the membrane and serve as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes to facilitate interaction with the cell’s environment.[3] Glycolipids embedded in the outer lipid layer serve a similar purpose
In the field of synthetic biology, cell membranes can be artificially reassembled.[5][6][7][8]. While Robert Hooke’s discovery of cells in 1665 led to the proposal of the cell theory, Hooke misled the cell membrane theory that all cells contained a hard cell wall since only plant cells could be observed at the time.[9] Microscopists focused on the cell wall for well over 150 years until advances in microscopy were made
This theory extended to include animal cells to suggest a universal mechanism for cell protection and development. By the second half of the 19th century, microscopy was still not advanced enough to make a distinction between cell membranes and cell walls
Fast Facts about the Cell Membrane [7]
The cell is the most basic unit of life on Earth, and the development of the cell membrane (or plasma membrane) may be one of the most important parts of the story of the evolution of life. Both prokaryotes (single-celled organisms that lack a distinct nucleus and other organelles) and eukaryotes (single-celled or multicellular organisms whose cells have a distinct nucleus and various organelles) have cell membranes that help the cell remain separate, in a sense, from the outside world
It also performs several other functions to maintain the cell’s homeostasis—that is, the cell’s state of equilibrium or stability as conditions change within the cell or in the outside environment.. It is made up of a double layer of phospholipids that separates the cell from the outside world.
A cell’s membrane is primarily made up of a double layer of phospholipids (fatlike, phosphorus-containing substances). Each layer is composed of phospholipid molecules that contain a hydrophilic (water-loving) head and a hydrophobic (water-repellent) tail
4.7: Eukaryotic Cells – The Plasma Membrane and the Cytoplasm [8]
4.7: Eukaryotic Cells – The Plasma Membrane and the Cytoplasm. – Explain the structure and purpose of the plasma membrane of a cell
As the outer layer of your skin separates your body from its environment, the plasma membrane separates the inner contents of a cell from its exterior environment. The plasma membrane can be described as a phospholipid bilayer with embedded proteins that controls the passage of organic molecules, ions, water, and oxygen into and out of the cell
The cell membrane is an extremely pliable structure composed primarily of two adjacent sheets of phospholipids. Cholesterol, also present, contributes to the fluidity of the membrane
Biology for Majors I [9]
– Contrast the composition and size of prokaryotic and eukaryotic cells. Cells fall into one of two broad categories: prokaryotic and eukaryotic
Animal cells, plant cells, fungi, and protists are eukaryotes (eu = true).. All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4) ribosomes, particles that synthesize proteins
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes
Biology Online Dictionary [10]
Definition: The cell’s outer membrane is made up of two layers of phospholipids with embedded proteins and separates the contents of the cell from its outside environment, as well as regulates what enters and exits the cell. Just like any non-living body possesses a plastic or paper packaging material that keeps the contents of the body intact, in shape, protected, and well-preserved, the cells have a protective outer layer called the “Cell membranes (CM)” or “Plasma membrane (PM)” or cytoplasmic membrane
What is a cell membrane? Basically, a cell membrane (or plasma membrane) is an ultrathin, plastic, dynamic, electrically charged, and selectively-permeable membrane layer that separates the cytoplasm from the extracellular matrix and helps in maintaining the cell structure and function. This should not be confused with the cell wall, which is an extra layer present outside of the cell membrane mainly in plants, bacteria, and fungi.
Being selectively permeable, the cell membrane allows the movement of both solvent and some selected solutes. We should take note here that the membrane is selectively permeable and not semi-permeable

3.3 Eukaryotic Cells – Concepts of Biology – 1st Canadian Edition [12]
Chapter 3: Introduction to Cell Structure and Function. – Describe the structure of eukaryotic plant and animal cells
– Describe the cytoskeleton and extracellular matrix. At this point, it should be clear that eukaryotic cells have a more complex structure than do prokaryotic cells
Before discussing the functions of organelles within a eukaryotic cell, let us first examine two important components of the cell: the plasma membrane and the cytoplasm.. Like prokaryotes, eukaryotic cells have a plasma membrane (Figure 3.9) made up of a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment
Structure of the Plasma Membrane [13]
By agreement with the publisher, this book is accessible by the search feature, but cannot be browsed.. A service of the National Library of Medicine, National Institutes of Health.
The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments. In the case of the plasma membrane, these compartments are the inside and the outside of the cell
The plasma membrane is the most thoroughly studied of all cell membranes, and it is largely through investigations of the plasma membrane that our current concepts of membrane structure have evolved. The plasma membranes of mammalian red blood cells (erythrocytes) have been particularly useful as a model for studies of membrane structure
Molecular Expressions Cell Biology: Plasma Membrane [14]
All living cells, prokaryotic and eukaryotic, have a plasma membrane that encloses their contents and serves as a semi-porous barrier to the outside environment. The membrane acts as a boundary, holding the cell constituents together and keeping other substances from entering
Small molecules, such as oxygen, carbon dioxide, and water, are able to pass freely across the membrane, but the passage of larger molecules, such as amino acids and sugars, is carefully regulated.. According to the accepted current theory, known as the fluid mosaic model, the plasma membrane is composed of a double layer (bilayer) of lipids, oily substances found in all cells (see Figure 1)
Phospholipids are characteristically hydrophilic (“water-loving”) at their phosphate ends and hydrophobic (“water-fearing”) along their lipid tail regions. In each layer of a plasma membrane, the hydrophobic lipid tails are oriented inwards and the hydrophilic phosphate groups are aligned so they face outwards, either toward the aqueous cytosol of the cell or the outside environment
Overview of Cells [15]
Cells are the microscopic units that make up humans and every other living organism. Some organisms consist of only one cell, while others (like humans) have trillions of cells!
Our cells do a lot for us: they synthesize proteins, convert nutrients from our food into energy we can use, and make up the tissues and organs in our bodies. Eukaryotic cells contain smaller structures, called organelles, that help it carry out these functions.
Mitosis occurs when a cell divides and creates two genetically identical copies of itself. Specialized sex cells can divide by meiosis, which occurs when a sex cell creates four daughter cells that are all genetically distinct
The cell. 3. Cell membrane. Atlas of plant and animal histology [16]
During the journey through the extracellular matrix toward the cell, the first cell structure to run into is the plasma membrane. Cells die several seconds after the plasma membrane integrity is lost
In eukaryotes, and some prokaryotes, there are also internal membranes that form organelles, separating the lumen of the organelle from the rest of the cytoplasm. Cell membranes are also platforms for proteins to carry out an outstanding amount of biochemical processes and molecular interactions that cells need to live and perform their functions.
The structure, organization, as well as physical properties of membranes, largely rely on amphiphilic lipids, i.e., those having hydrophilic and hydrophobic parts. Lipids are arranged as a bilayer with their hydrophobic parts in the inner part, which is made up of fatty acid chains trying to avoid a hydrophilic environment, and their hydrophilic parts in contact with water (Figure 1)
CELL BIOLOGY [17]
Cells are the structural and functional unit of all living organisms. Some organisms, such as bacteria, are unicellular, consisting of a single cell
Even more amazing is that each cell stores its own set of instructions for carrying out each of these activities.. It is important to know what organism the cell comes from
Prokaryotes are capable of inhabiting almost every place on the earth, from the deep ocean, to the edges of hot springs, to just about every surface of our bodies. Prokaryotes also lack any of the intracellular organelles and structures that are characteristic of eukaryotic cells
Review: Cells, Tissues, and Membranes [18]
Here is what we have learned from Cells, Tissues, and Membranes:. – Basically, a cell consists of three parts: the cell membrane, the nucleus, and between the two, the cytoplasm.
It determines how the cell will function, as well as the basic structure of that cell.. – All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
Primary types of body tissues include epithelial, connective, muscular, and nervous tissues.. – Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.
3.2 Comparing Prokaryotic and Eukaryotic Cells – Concepts of Biology [19]
– Name examples of prokaryotic and eukaryotic organisms. – Compare and contrast prokaryotic cells and eukaryotic cells
Cells fall into one of two broad categories: prokaryotic and eukaryotic. The predominantly single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes (pro- = before; -karyon- = nucleus)
All cells share four common components: 1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; 2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; 3) DNA, the genetic material of the cell; and 4) ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.

Q: Which type of cells contain a cell membrane, cytoplasm, ribosomes and DNA?. Which type of cells contain a cell membrane, cytoplasm, ribosomes and DNA?
– Prokaryotic cells lack a nucleus and membrane-bound structures.. – Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
Animal and plant cells [22]
– Cells are the smallest unit of life and the building blocks for all organisms.. – Animal and plant cells differ and they have similarities.
Play an Atomic Labs activity to look at onion cells under a microscope.. Play this game to see what different cells look like through different microscopes.
Others, like trees and blue whales, are made from millions or even billions of cells. These often have different types of cells, each with a different function
The Cell Membrane [23]
All living cells and many of the tiny organelles internal to cells are bounded by thin membranes. These membranes are composed primarily of phospholipids and proteins and are typically described as phospholipid bi-layers.
In some membranes there are only a few cholesterol molecules, but in others there are as many cholesterols as phospholipids according to Audesirk & Audesirk. Cholesterol makes the bilayer stronger, more flexible but less fluid, and less permeable to water-soluble substances such as ions and monosaccharides.
It shows that the cell membrane contains much more than just the phospholipid bi-layer.. Essential and continuous parts of the life of a cell are the taking in of nutrients and the expelling of wastes
The cell: Types, functions, and organelles [24]
A cells is the smallest living organism and the basic unit of life on earth. Cells have three parts: the membrane, the nucleus, and the cytoplasm.
They function on their own, creating their own energy and self-replicating — the cell is the smallest unit of life that can replicate. Whether in plants, humans, or animals, they connect to create a solid, well formed organism
He gave them their name because they resembled the “cella,” the Latin term for “small rooms” where monks lived in monasteries.. Cell types can look different, and carry out distinct roles within the body.
