Question

Differentiate between meristematic and permanent tissues in plants. Also Define the process of differentiation

​

Answer 1

$anwer$

The process by which the cells divide meristematically to take a permanent shape, size and function is called differentiation.

...

Meristematic tissue Permanent tissue

It is a simple tissue. It can be simple, complex or specialized

$\small\mathbf\orange{{Merismatic \: Tissues : }}$

• Meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant.
• Meristematic tissues contain living cells with varied shapes.
• The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc.
• These cells help to increase the length and girth of the plant.

$\small\mathbf\purple{{Permanent \: Tissues : }}$

• Simple permanent tissues are found below the epidermis of the plant, spread around in layers of cells.
• These tissues are made up of one type of cells .
• They perform a variety of functions like protection storage mechanical support etc .
• Examples : Parenchyma , collenchyma and sclerenchyma

$\small\mathbf\green{{Differentiation : }}$

Differentiation in plants refers to the processes by which distinct cell types arise from precursor cells and become different from each other. Other cells such as the water-conducting vessel elements undergo cell death as part of their differentiation pathway and thus can never transdifferentiate to another cell type.
