Question

differentiate between cells of parenchyma and sclerenchyma

Answer 1

•Parenchyma cells have thin primary cell wall amdno secondary cell wall whereas sclerenchyma cells have both primary and secondary cell wall.

•Parenchyma cells easily allow molecules to enter into cells and expel substances easily from the cell whereas permeability of sclerenchyma is limited because secondary cell wall is present.

•Parenchyma cells are well adapted for photosynthesis whereas sclerenchyma cells have low photosynthetic ability.

•Parenchyma cells can produce new cells whereas sclerenchyma cells do not produce new cells.

•Parenchyma stores food materials whereas sclerenchyma do not store anything.

Answer 2

parenchyma: it is a living tissue.
                      it is a barrel shaped cells.
                      no secondary thickening.
most of the plant body composed of parenchymatous tissue.
sclerenchyma : it is a dead tissue.
                         it has secondary thickening.
                         it has many types.        (eg.bracysclerids,osteosclerids,fibres,lignin............)
it is mostly found in branches,stem
