Question

how will you differenciate between paraenchyama and collenchyma in the slide of a plant tissue​

Answer 1

Parenchyma:-

1. Parenchyma cells are present in the epidermis, cortex, pith and pericycle. Meristematic cells are parenchymatous.
2. Thin cell wall.
3. Intercellular space is present.
4. No pectin deposition.
5. Shape - Isodiametric
6. Permanent tissue.

Collenchyma:-

1. It occurs in the peripheral part of elongating organs like stem and petiole, usually appearing as a continuous ring beneath the epidermis.
2. Unequally thickened cell wall
3. Intercellular space is absent.
4. Pectin deposition is found at the corners.
5. Shape - Polygonal.
6. Permanent tissue sometimes revives meristematic activity.
