Question

differentiate between parenchyma, collenchyma and sclerenchyma on the basis of their cell wall at least 2 point for all three​

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.

hope it's work

Answer 2

Answer:

• Parenchyma is the most simple and specialized tissue which is concerned mainly with the vegetative activities of the plant. The cells are isodiametric with well-developed intercellular spaces, vacuolated cytoplasm and cellulosic cell wall.

• Collenchyma is the tissue of the primary body. The cells of the tissue contain protoplasm and are living without intercellular spaces. The cell wall articulate at the corners and are made up of cellulose, hemicellulose, and pectin.

• Sclerenchyma is the thick-walled cell tissue. In the beginning, the cell is living and have protoplasm,but due to deposition of impermeable secondary board lignin, they become dead thick and hard.
