Question

What Is Parenchyma , Chollenchyma , Sclerenchyma.
Explain In Brief About It.​

Answer 1

. Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions.

. Collenchyma is a supporting tissue composed of more or less elongated living cells with unevenly thickened, nonlignified primary walls.

. Sclerenchyma is one of the three types of ground, or fundamental, tissue in plants; the other two types are parenchyma (living thin-walled tissue) and collenchyma (living support tissue with irregular walls). Sclerenchyma cells occur in many different shapes and sizes, but two main types occur: fibres and sclereids.

Answer 2

• parenchyma= Parenchyma is a generalized plant cell type and defined as the functional tissues in all higher plants. ... In leaves, these cells are also responsible for photosynthesis and the exchange of gases.

• Collenchyma tissue= is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.

• Sclerenchyma= is a type of permanent tissue. They are dead, long, thin narrow cells with thickened walls without any internal space. This tissue makes the plant hard and stiff. They provide mechanical support to plants.
