Question

Describe the structure of collenchyma tissue.

Answer 1

Simple Permanent Tissue:

1. They are made up of a single cell type that, in most circumstances, has the same origin, structure, and function.
2. There are three types of simple permanent tissue:

• Parenchyma
• Collenchyma
• Sclerenchyma

Structure of Collenchyma:

1. Long and thick-walled cells.
2. Cellulose and pectin make up the cell wall.
3. Due to the presence of pectin, it is the only tissue with the highest refractive index.
4. It's present in the dicot leaf's epidermis and vascular bundle.
5. In the cells, the amount of chloroplast is lower.
6. There are no intercellular gaps between the cells.

Functions:

1. The edges of the stem and leaves of herbaceous angiosperms are where collenchyma is most frequently found.
2. The purpose of the collenchymatous tissues in these plants is to give the non-woody stem and leaves mechanical support and tensile strength.
3. In order to promote growth, collenchymatous tissues are stretched during cell elongation.
4. Herb leaves and stems can bend in the wind without breaking because collenchyma is present.
