Plant Development I: Tissue differentiation and function [2]
– Recognize relationships between plant embryonic structures and mature plant morphology. – Describe the organization and functions of plant organs (roots, stems, and leaves), and relate morphology to function
– Differentiate between monocot and eudicot body plan characteristics, including organization of the vascular and ground tissues in stems and roots. The information below is adapted from OpenStax Biology 32.2
Auxin behaves like a cytoplasmic determinant, setting up the apical/basal axis (similar to the anterior/posterior axis in animals) in the very first cell division. Following fertilization of the ovule by sperm, the plant zygote divides asymmetrically which segregates the auxin as follows:
Wikipedia [3]
Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.[1][2] The word xylem is derived from the Ancient Greek word ξύλον (xylon), meaning “wood”; the best-known xylem tissue is wood, though it is found throughout a plant.[3] The term was introduced by Carl Nägeli in 1858.[4][5]
Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels.[6]. Xylem also contains two other type of cells: parenchyma and fibers.[7]
– in secondary xylem, laid down by a meristem called the vascular cambium in woody plants. – as part of a stelar arrangement not divided into bundles, as in many ferns.

Identify the tissue that transports water to the plant body.. Hint:The vascular bundle consists of two types of transport tissue, namely, xylem and phloem
Especially for large trees, the long distance transportation from the roots to the leaves plays a vital role. Hence for this function, an elaborate system is present in the plant body.
>Option A: Xylem- The xylem consists of tracheary elements, that is the trachea and xylem vessels, along with xylem parenchyma and xylem fibers. These are hollow conductive tubes helping in transport of water, hormones, nutrients, etc
Water Uptake and Transport in Vascular Plants [5]
If water is so important to plant growth and survival, then why would plants waste so much of it? The answer to this question lies in another process vital to plants — photosynthesis. To make sugars, plants must absorb carbon dioxide (CO2) from the atmosphere through small pores in their leaves called stomata (Figure 1)
The balance between transpiration and photosynthesis forms an essential compromise in the existence of plants; stomata must remain open to build sugars but risk dehydration in the process.. Essentially all of the water used by land plants is absorbed from the soil by roots
Roots grow from their tips and initially produce thin and non-woody fine roots. Fine roots are the most permeable portion of a root system, and are thought to have the greatest ability to absorb water, particularly in herbaceous (i.e., non-woody) plants (McCully 1999)

The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant. Most extant plants on Earth have vascular systems, including the lower vascular plants (lycophytes and ferns), gymnosperms, and angiosperms.
The vascular system of monocots (e.g., grasses) consists of vascular bundles scattered across the stem, while the vascular system of dicots (e.g., roses) features vascular tissues that surround a central pith. Vascular rays extend radially across the stem, assisting in conduction from the vascular bundles to tissues alongside them.
3.1.3: Plant Tissues [7]
– Describe the difference between meristematic and non-meristematic tissues.. – Compare and contrast dermal, ground, and vascular tissue.
Plant tissues are composed of cells that are similar and perform a specific function. Each organ itself is also specific for a particular function.
Cells of the meristematic tissue are found in meristems, which are plant regions of continuous cell division and growth. Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant
Biology for Majors II [8]
– Identify the different tissue types and organ systems in plants. Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions
Cells of the meristematic tissue are found in meristems, which are plant regions of continuous cell division and growth. Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant
Meristematic tissues consist of three types, based on their location in the plant. Apical meristems contain meristematic tissue located at the tips of stems and roots, which enable a plant to extend in length
Vascular Plants [9]
If you’re driving down a sunny road lined with palm trees, hiking through a damp forest coated with ferns, or exploring an arid desert dotted with cacti, you’re surrounded by a group of plants known as vascular plants. These plants have something special that helps them survive on land: vascular tissue.
It has two parts called xylem and phloem that conduct water, food, and nutrients. This helps the plant adapt to different environments, making it easier for them to thrive
So next time you’re out in nature, take a closer look at the plants around you. You might be surrounded by some incredible vascular plants! And if you’re ever asked what they are, you’ll know exactly what to say.
GCSE Combined Science Revision [10]
Plants require a transport system to deliver raw materials for photosynthesis to the leaves and to deliver the sugar made to other parts of the plant for use or storage.. Plants have two transport systems – xylem and phloem
The xylem transports water and minerals from the roots up the plant stem and into the leaves.. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels
Transport in the phloem is therefore both up and down the stem. Transport of substances in the phloem is called translocation.
Biology 2e, Plant Structure and Function, Plant Form and Physiology, The Plant Body [11]
Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions. Plant tissue systems fall into one of two general types: meristematic tissue, and permanent (or non-meristematic) tissue
Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant. In contrast, permanent tissue consists of plant cells that are no longer actively dividing.
Apical meristems contain meristematic tissue located at the tips of stems and roots, which enable a plant to extend in length. Lateral meristems facilitate growth in thickness or girth in a maturing plant
Topic 9.1 Transport in the Xylem of Plants [12]
In the Transport in the Xylem unit we will learn how plants are able to move water and nutrients from the roots to the leaves. Transpiration is the driving force that moves water through the plant
This water is replaced by additional absorption soil leading to a continuous column of water in the plant’s xylem. Plants reduce water loss by closing their stomata, developing thick cuticles, or by possessing leaf hairs to increase the boundary layer
– Structure and function are correlated in the xylem of plants.. – Use models as representations of the real world—mechanisms involved in water transport in the xylem can be investigated using apparatus and materials that show similarities in structure to plant tissues
Plant tissues. Vascular. Atlas of plant and animal histology. [13]
Vascular plants, unlike non vascular plants, have specialized tissues for transporting water and inorganic and organic substances. These tissues are known as vascular tissues: xylem and phloem, which appeared about 450 million years ago, when plants colonized the land
Physiologically, plants need vascular tissues to increase their size by distributing water and organic substances, but have also a role in supporting the aerial part of the plant, including stem, branches, and organs, such as leaves, flowers and fruits, and also give strenght to roots. Different parts of the plant body can communicate between each other by sending meaningful molecules, like some fitohormones, via the vascular system.
During primary plant grow, xylem and phloem originate from the procambium meristem. Protoxylem and protophloem originate first at both the embryonary and postembryonary stages, but they are progressively replaced by metaxylem and metaphloem, which are the mature vascular system in organs that only show primary grow

Plants: Essential Processes: Water Transport [16]
The movement of plants from water to land has necessitated the development of internal mechanisms to supply all the parts of the plant with water. As discussed in Plant Classification, Vasular Tissues , tracheophytes (including virtually all terrestrial plants except for mosses and liverworts), have developed complex vascular systems that move nutrients and water throughout the plant body through “tubes” of conductive cells
The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots (where they are taken in) to the rest of the plant. Phloem, which is made up of living cells, carries the products of photosynthesis (organic nutrients) from the leaves to the other parts
The major mechanism by which water (along with dissolved materials) is carried upward through the xylem is called TATC (Transpiration-Adhesion-Tension-Cohesion). It should be noted that TATC, while supported by most scientists, is speculated but not proven to be at work in very tall trees
How do large trees, such as redwoods, get water from their roots to the leaves? [17]
“Water is often the most limiting factor to plant growth. Therefore, plants have developed an effective system to absorb, translocate, store and utilize water
Plants contain a vast network of conduits, which consists of xylem and phloem tissues. This pathway of water and nutrient transport can be compared with the vascular system that transports blood throughout the human body
These conducting tissues start in the roots and transect up through the trunks of trees, branching off into the branches and then branching even further into every leaf.. “The phloem tissue is made of living elongated cells that are connected to one another
