What is Permanent Tissue in Plants?

In Class 9 Biology (Tissues), plant tissues are divided into two main categories: Meristematic Tissue (which constantly divides and grows) and Permanent Tissue.

Question (Click to Flip)

What is permanent tissue in plants?

Answer

Permanent tissues are groups of mature plant cells that have lost their ability to divide. They take on specific, permanent roles in the plant, such as storing food, providing support, or transporting water and nutrients.

Key Facts

Permanent Tissue: Plant cells that no longer divide.

Differentiation: The process where dividing cells take a permanent shape and job.

Simple Tissue: Parenchyma, Collenchyma, Sclerenchyma.

Complex Tissue: Xylem (Water transport) and Phloem (Food transport).

What is Permanent Tissue?

Permanent Tissues are mature plant tissues that have lost their ability to divide and grow.

  • How are they formed?: They are actually formed from meristematic tissues. Once the dividing cells of the meristem reach maturity, they take on a specific shape, size, and function. This process of taking a permanent shape and function is called Differentiation.

Types of Permanent Tissue

Permanent tissues are further divided into two types based on their structure:

  1. Simple Permanent Tissue: These are made up of only one type of cell that look and function the same. Their main jobs are protection, support, and storing food.

    • Examples: Parenchyma (stores food), Collenchyma (provides flexibility/bending), and Sclerenchyma (provides hard, dead support like a coconut shell).

  2. Complex Permanent Tissue: These are made up of more than one type of cell working together as a single unit. Their main job is transportation.

    • Examples: Xylem (transports water from roots to leaves) and Phloem (transports food from leaves to all parts of the plant).
