Question

Explain the functions of parencyma, collenchyma and sclerenchyma​

Answer 1

Answer:

$\sf{\bold{\green{\underline{\underline{PARENCHYMA}}}}}$

The function of parenchyma cells is in the storage of foods, in gaseous exchange, and in photosynthesis.

$\sf{\bold{\red{\underline{\underline{COLLENCHYMA}}}}}$

Collenchyma cells provide mechanical support and elasticity to the plant.

$\sf{\bold{\blue{\underline{\underline{SCLERENCHYMA}}}}}$

the sclerenchyma cells provides mechanical support to the plant. It also supports transportation of water and nutrients to the plants.

Answer 2

Answer:

Parenchyma:

1.Tissue first time evolved in bryophyte.

2.Thin walled cells, oval or spherical in structure.

3.Cell wall mainly composed of cellulose & pectin.

Collenchyma :

1.: It is the living mechanical tissue.

2.Elongated cells with thick corners.

3.Localized cellulose & pectin thickening.

Sclerenchyma :

1.Composed of extremely thick walled cells with little or no protoplasm.

2.Cells are dead & possess very thick lignified walls.

3.Intercellular spaces are absent.
