Question

What is parenchyma,Chlorenchyma and Sclerenchyma and also its functions

Answer 1

Heyya!

Parenchyma - Loosely packed cells with lots of intercellular spaces are called parenchyma cells

Functions of parenchyma cells include: photosynthesisstoragesecretion

Collenchyma - They are a group of cells in which the corners are thickened.

Functions of collenchyma cells include:supportsome involvement in transport of nutrients

Sclerenchyma - In such cells, the whole cell is thickened unlike the collenchyma cells. This thickeneing is because of a chemical substance known as lignin. This makes the plant part hard.

Functions include:
supportprotectiontransport of water and nutrients.

Hope it helps!☺️

Answer 2

(i) Parenchyma:

Parenchyma is the most common tissue which is morphologically and physiologically simple and unspecialized. These cells are found in epidermis, cortex, pericycle, pith etc. They are responsible for photosynthesis, storage of food, secretion etc.

(ii) Collenchyma:

Collenchyma are living tissues composed of more or less elongated cells and often have some chloroplast to carry on photosynthesis. It is generally situated below the epidermis.

(iii) Sclerenchyma:

Cells are long, thick-walled and lignified with tapering ends. These are fibre like in appearance and also known as sclerenchymatous fibre. These are dead cells and perform mechanical function.
