Question

Differentiate beetween parenchyma and collenchyma

Answer 1

Parenchyma tissues consist of living cells that are thin-walled and they may be compact or have extensive spaces between the cells. They are also called ground, or fundamental, tissue and makes up the mesophyll (internal layers) of leaves and the cortex (outer layers) and pith (innermost layers) of stems and roots.


Collenchyma cells consists of thin primary walls and provide extra structural support in regions of new growth. Collenchyma cells have walls which during their development and extension are mainly cellulosic.

Answer 2

Answer:

PARENCHYMA :-

❉The cells of parenchyma aree soft,thin walled and loosely packed.

❉They store food ,bears chloroplasts contain larger cavities.

❉Cell wall is primary made up of cellulose.

❉Cells are oval , round and rectangular in shape.

COLLENCHYMA :-

❉The cells of collenchyma are thick walled and compactly arranged.

❉They give mechanical strength in young tissue of stem.

❉Cell wall has deposition of extra cellulose.

❉Cells are elongated , round and spherical in shape.
