Xylem and phloem are the two most important complex tissues in a plant, as their primary functions include the transport of water, ions, and soluble food substances throughout the plant.
What are the major plant tissues and their functions?
| Tissue Cell Types Function | Epidermal tissue Parenchyma Protect plant tissues and prevent water loss | Ground tissue Parenchyma Collenchyma Sclerenchyma Makes up bulk of plant mass | Meristematic tissue Parenchyma Divide to produce new growth |

What are the main tissue in plants?
They differentiate into three main tissue types: dermal, vascular, and ground tissue . Each plant organ (roots, stems, leaves) contains all three tissue types: Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots).
What is the strongest plant tissue?
Sclerenchyma cells have thickened lignified walls, which make them strong and waterproof. They are commonly classified into support types and conducting forms. Support sclerenchyma is comprised of sclereids and fibers. This tissue reduces wilting, but it is energetically costly for the plant to create.
What is the most important plant organ?
Roots are important organs in all vascular plants. Most vascular plants have two types of roots: primary roots that grow downward and secondary roots that branch out to the side. Together, all the roots of a plant make up a root system.
What is the main function of Collenchyma tissue?
Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants , allowing for easy bending without breakage.
What is the plant tissue function?
Functions of plant tissues
Help provide mechanical strength to organs . They help in providing the elasticity and flexibility to the organs. They divide to produce new cells and help in the growth of the plants. They help in various cellular metabolisms like photosynthesis, regeneration, respiration, etc.
What is plant tissue with diagram?
Plant tissue is a collection of similar cells performing an organized function for the plant . Each plant tissue is specialized for a unique purpose, and can be combined with other tissues to create organs such as leaves, flowers, stems and roots.
How many tissue types are there?
There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
What is an example of a plant tissue?
Dermal tissue , for example, is a simple tissue that covers the outer surface of the plant and controls gas exchange. Vascular tissue is an example of a complex tissue, and is made of two specialized conducting tissues: xylem and phloem. ... The xylem and phloem always lie adjacent to each other (Figure 1).
What is a human and plant example of an organ?
An organ is a self-contained group of tissues that performs a specific function in the body. The heart, liver, and stomach are examples of organs in humans. Organs are found in most animals and plants. ...
Which plant tissue makes up the thinnest layer?
| Structure Function | Layer of cells covering surface of entire plant. Acts as a barrier to fungi and other microorganisms and pathogens. | Layer is thin and transparent. Allow for light to pass through, thereby allowing for photosynthesis in the tissues below. |

Which plant cell has no nucleus?
=》The only plant cell without nucleus is Cabium(Vascular) cell .
What are the 4 major plant organs?
- Plants are made up of organs, including roots, leaves, the stem and reproductive organs.
- Each organ has its own functions.
- Together, the organs of a plant allow it to carry out the seven processes of life.
Which human organ is most similar to a plant organ?
There are several similarities between the human and plant organ systems. The opening and closing of the stomata are regulated by guard cells. Circulatory Systems : Both of the systems have a very similar function: to carry substances around the body.
What will happen if roots are damaged?
Damaged roots can cause buds and twigs to immediately die , weakening the plant. The weakened plant may then begin to show decline symptoms such as lack of vigor and reduced growth. Plants with damaged roots show symptoms on the side of the plant where roots have been severed.
