Question

3 ways in which sclernchyma differs from parenchyma

Answer 1

parenchyma- large thin wall cells, usually a single large vacuole, found in soft parts of plants such as cortex(outer region) and pith(central region) ,may store food as in potatoes and provide temporary support to the plant.

sclerenchyma - composed of long narrow cells which have become dead. B cells develop very thick walls due to the deposition of Lignin. this tissue provides strength to plant parts.it is found in stems and veins of the leaves.

Answer 2

parenchyma
.the cells are living and have large intercellular spaces between them.
in aquatic plants large cavity are present in parenchyma to give buoyancy to the plants to help them float. this type of parenchyma is called arenchyma.

sclerenchyma
.it is dead simple permanent tissue which makes the plant hard and stiff.
.the cells of schlerenchyma are long narrow and closrly packed without any intercellular spaces.
.sclerenchyma gives strenght and rigidity to plant body.
