Question

difference between the cells of parenchyma and collenchyma

Answer 1

Hi friend,

DIFFERENCES BETWEEN THE CELLS OF PARENCHYMA AND COLLENCHYMA ARE:-

•Parenchyma has thin cell wall whereas collenchyma has thick cell wall.

•Intercellular space is present in parenchyma whereas it is absent in collenchyma.

•Functions of parenchyma are storage of food materials,chloremchyma carries photosynthesis,Aerenchyma helps plants to float on water and also in exchange of gases.
WHEREAS
Functions of Collenchyma are giving mechanical support,it carries photosynthesis if chloroplast in present.It is flexible.

Hope it helps

Answer 2

PARENCHYMA

• Parenchyma is an unspecialised simple permanent tissue.
• Their shape may be oval, round, polygonal or elongated in shape.
• They have thin cell wall made of cellulose.
• They have large intracellular spaces between them.
• They have neucleus in their cell and hence living.
• They are present in plant's roots, stems, leaves, flowers or fruits.

COLLENCHYMA

• Collenchyma is an specialised simple permanent tissue.
• Their shape may be transversed or longitudnal.
• They have thick wall with deposits of hemicellulose, and pectin.
• They have less intracellular spaces between them.
• They have neucleus in their cell and are living.

• It is found below epidermis of leaf stalk and leaf mid-ribs.
