Question

1. Different between parenchyma, collenchyma and sclerchyma on the basis of their cell wall?​

Answer 1

Answer:

Parenchyma has a thin cell wall of their cells, and are made up of cellulose. Whereas collenchyma cells have an uneven cell wall made up of pectin and hemicellulose. There is a hard and thick cell wall present of the sclerenchyma cells, which is made up of the lignin

Answer 2

Answer:

Parenchyma:

•It consists of thin-walled living cells.

•They are involved in food storage.

•Comprises a thin cell wall and made up of cellulose.

Collenchyma:

•It consists of thin-walled living cells.

•They are the chief mechanical tissue in young plants, particularly dicot stems.

•It comprises an uneven cell wall and is made up of pectin and hemicellulose.

Sclerenchyma:

•It consists of dead cells.

•It is mainly a mechanical tissue.

•It comprises the hard and thick cell wall and is made up of lignin.
