Compare the three types of simple permanent tissue on the basis of its location ,cell wall & its function
Answers
Answer:
Simple permanent tissues:
The completely grown tissues that have no ability to divide further are known as permanent tissues.
The permanent tissues are formed by the division and differentiation of meristematic tissues.
The three types of simple permanent tissues are Parenchyma, Collenchyma, and Sclerenchyma.
Parenchyma:
1.Parenchyma are tissues that have unspecialized living cells that have thin walls.
2.The cells are loosely packed and thus there are intracellular spaces.
3.The function of parenchyma is to support and protect the plant and store food.
Collenchyma:
Collenchyma are tissues that have thin-walled cells.
The cells have a thickening of cellulose, water, and pectin at the corners.
The function of collenchyma is to support, and provide elasticity and tensile strength to the plants.
Sclerenchyma:
Sclerenchyma are the tissues that have thick-walled cells and dead cells.
The cell walls of these cells are thick due to the deposition of lignin.
The function of sclerenchyma is to provide mechanical stiffness and strength to the plant.
