what are simple permanent tissue explain their structure location and function
Answers
Answer:
A simple permanent tissue is that tissue which is made up of similar permanent cells that carry out the same function or similar set of functions. Simple permanent tissues are of three types – parenchyma, collenchyma and sclerenchyma.Permanent plant tissues are found in mature plants. Simple tissues are composed of only one type of cell.

Answer:
ANSWER
Permanent tissues are a group of living or dead cells which are formed by meristematic tissues that have lost their ability to divide.
That is, these tissues have undergone differentiation and are incapable of meristematic activities.
It is of two types:-
1) Simple permanent tissues 2) Complex permanent tissues
Simple permanent tissues are a group of cells which are similar in origin, structure and function.
They are of three types:-
a) Parenchyma- are unspecialised living cells which have thin cell walls and are loosely packed so that the intercellular spaces are found between cells of this tissue.
Its main function is to support and protect the plants and store food.
b) Collenchyma - are living tissues which also have thin-walled cells but possess thickening of cellulose, water and pectin substances at the corners of the cells.
Its main function is to provide mechanical support, elasticity, and tensile strength to the plants.
c) Sclerenchyma- are tissues consists of thick-walled and dead cells.
The cells have hard and thick walls because of lignin deposition.
It provides mechanical stiffness and strength.
