Question

answer these four questions

Answer 1

1) Meristematic cells have a prominent nucleus and a dense cytoplasm but lack a vacuole, this is so becausemeristematic cells have an ability to divide and form new cell. ... But, thereis no point in storing food and other nutrients when the cell has to divide.

2) There are no intercelluar spaces present in the scerlenchymatous tissue as it provides rigidity to the plants part in which they are present.They contain a chemical called lignin which acts as a cement like substance which hardens the cels & also the cells of sclerenchyma are dead.

3) It is a mechanical tissue which provides support and elasticity to the branches of a tree so that, they move and bend freely in high wind velocity. (e) It is difficult to pull out the husk of a coconut tree due to the presence of sclerenchyma tissue.

4) The husk of a cocunut tree is hard to pull out because ,it is made up of scelerenchyma tissues which is ade of dead cells.Sclerenchyma gives rigidity and stiffness to the plant and also due to the presence of lignin on the walls of the cells we find it tough to pull the husk out.
