Question

Short note on parenchyma,collenchyma and scelrenchyma

Answer 1

Answer:

hey! mate here is my answer for your question

Explanation:

Parenchyma cells help in storage of foods, in gaseous exchange, and in photosynthesis.

Collenchyma cells provide mechanical support and elasticity to the plant.

Sclerenchyma cells provide mechanical support to the plant. It also supports transportation of water and nutrients to the plants.

I hope it will helps you and mark me brainliest ♥♥♥♥!!!

Answer:

sclerenchyma:- 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. The cells are rigid and nonstretchable and are usually found in nongrowing regions of plant bodies, such as the bark or mature stems. 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.

Collenchyma:- Collenchyma, in plants, support tissue of living elongated cells with irregular cell walls. Collenchyma cells have thick deposits of cellulose in their cell walls and appear polygonal in cross section. The strength of the tissue results from these thickened cell walls and the longitudinal interlocking of the cells. Collenchyma may form cylinders or occur as discrete strands and is one of the three ground, or fundamental, tissues in plants, together with parenchyma (living thin-walled tissue) and sclerenchyma (dead support tissue with thick cell walls).

Parenchyma is a type of simple permanent tissue that makes a major part of ground tissues in plants, where other tissues like vascular tissues are embedded. They are non-vascular and composed of simple, living and undifferentiated cells, which are modified to perform various functions. The other simple permanent tissues are:
