Question

pls ans me ????????? 9th state cillabs tissues???????​

Answer 1

Explanation:

1 ans:

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).

2 ans:

Meristematic tissue has a number of defining features, including small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces. The apical meristem (the growing tip) functions to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.

3 ans:

1. The apple peel is composed of epidermis covered with a cuticle and a multi-layered hypodermis,
2. Apical meristem tissue
3. collenchyma
4. sclerenchyma
5. Apical meristem

4 ans:

parenchyma

1. The living plant cells are originating from ground and protoderm meristem. These type of cells are most abundantly found in plants tissue.
2. These type of cells are present in every soft part of the plant.
3. Unspecialized and living cells.
4. There are various shapes of the cells, but generally, they are isodiametric.
5. Thin cell wall present.
6. The cell wall is made up of cellulose.
7. Parenchyma cells help in storage of foods, in gaseous exchange, and in photosynthesis.

collenchyma

1. The type of living plant cells originating from the pro-cambium. The epidermal layers of the plant are made of collenchyma cell.
2. These cells are found in specific part of the plant like leaves, stems, and petioles.
3. Specialized cells and living cells.
4. Elongated cells are present.
5. Uneven cell wall.
6. The cell wall is made up of pectin and hemicellulose.
7. Collenchyma cells provide mechanical support and elasticity to the plant.

5 ans:

a meristem developing between regions of mature or permanent tissue (as at the base of the grass leaf) — compare apical meristem, lateral meristem.
