Question

What is meant by parenchymatous and sclerenchymatous cells?​

Answer 1

Answer:

• Parenchyma tissue is composed of thin-walled cells and makes up the photosynthetic tissue in leaves, the pulp of fruits, and the endosperm of many seeds. Collenchyma cells mainly form supporting tissue and have irregular cell walls. They are found mainly in the cortex of stems and in leaves.

• Sclerenchyma, in plants, support tissue composed of any of various kinds of hard woody cells. Mature sclerenchyma cells are usually dead cells that have heavily thickened secondary walls containing lignin. ... Sclerenchyma cells occur in many different shapes and sizes, but two main types occur: fibres and sclereids.
