Permanent tissue

Definition

Permanent tissue consists of plant cells that have completed their growth and differentiation. These cells are typically specialized for specific functions within the plant body.

5 Must Know Facts For Your Next Test

1. Permanent tissues are classified into simple and complex tissues.
2. Simple permanent tissues include parenchyma, collenchyma, and sclerenchyma.
3. Complex permanent tissues include xylem and phloem, which are essential for transport in plants.
4. Parenchyma cells are involved in storage, photosynthesis, and tissue repair.
5. Sclerenchyma cells provide mechanical support due to their thick, lignified cell walls.
