Give the characteristics of simple permanent tissue. Also explain its type
Answers
Answer:
These are also known as homogenous tissues. They are made up of a single cell type, usually with the same origin, structure, and function.
Simple permanent tissue is further classified into three types:
Parenchyma
The cells have an oval or round shape.
The cell wall is made up of hemicellulose or cellulose.
The cell is thin-walled.
The cells have vacuoles and very small nucleus.
It is found in all parts of the plant.
The protoplasm is living and dense.
Collenchyma
Cells are long and thick walled.
The cell wall is made up of cellulose and pectin.
It is the only tissue with the highest refractive index due to the presence of pectin.
It is found in hypodermis of dicot stem and the vascular bundle of dicot leaf.
The amount of chloroplast is less in the cells.
The cells have no intercellular spaces.
Sclerenchyma
These are dead tissues, very hard and rigid in texture.
Cells are thick walled with various size and shapes.
These provide mechanical support and rigidity to the plant.
Hey mate
Simple permanent tissues are again classified into three main types.
They are parenchyma, collenchyma, and sclerenchyma. Parenchyma – The cells of this tissue are living, with thin cell walls. ... It mainly acts as a packing tissue, providing mechanical support.
