Question

What are the four tissue types in a plant?

Answer 1

Plant tissues:

1. A tissue is a collection of cells with similar configurations that collaborate to perform a specific function.
2. Permanent and meristematic tissues are two types of plant tissues.

Meristematic tissue:

1. Has the ability to divide quickly and develop quickly.
2. They contribute to the vegetation's major growth.
3. These cells are responsible for the plant's growth in length and diameter.
4. Meristematic cells are living cubical cells with a large nucleus.
5. Intercalary, lateral, and apical meristems are classified according to the section where the meristematic tissues exist.

Apical meristem:

1. Exists at the apical or growing tips of stems and roots.
2. The plant's length is increased by the apical meristem.
3. Lateral meristem is a type of meristem that is found on the radial portion of the stem or root containing this substance.
4. The plant's thickness is increased by the lateral meristem.
5. An intercalary meristem is a type of meristem found at the base of the leaves or at the internodes.
6. The internode's size is increased by the intercalary meristem. Meristematic cells that are too old to distribute and convert into permanent tissues lose their ability to do so.

Permanent tissues:

1. Permanent tissues: these cells have lost their ability to distribute, but they are specialized to provide the plant with elasticity, flexibility, and strength.
2. They are divided into three types based on their function: sclerenchyma, collenchyma, and parenchyma.

Complex permanent tissue:

1. Phloem and xylem are examples of complex permanent tissue.
2. Water and solvable constituents are transported through the xylem, which is very useful.
3. The xylem parenchyma, fibres, vessels, and tracheids make up this structure.
4. Phloem plays an important role in the transport of food particles. The phloem parenchyma, phloem fibres, companion cells, sieve cells, and sieve tubes make up the phloem.

Parenchyma:

1. These are polygonal cells that are alive and have a large central vacuole, as well as intercellular spaces between them.
2. Ground tissue and pith are created by parenchymatous cells.
