Question

Name the different types of permanent tissues in plants.

Accepted Answer

Permanent tissues in plants are groups of cells that have ceased to divide and have taken on specific functions. There are three main types of permanent tissues in plants:

Parenchyma Tissue: Parenchyma is the most common type of permanent plant tissue. These cells have thin cell walls and remain alive at maturity. Parenchyma cells are versatile and can perform various functions, including photosynthesis (in leaves), storage of water and nutrients (in roots and stems), and providing support to non-woody plant structures.

Collenchyma Tissue: Collenchyma cells have unevenly thickened primary cell walls and are living at maturity. They provide flexible structural support to growing plant parts, such as young stems and petioles. Collenchyma cells can elongate as the plant grows.

Sclerenchyma Tissue: Sclerenchyma cells have thick, lignified (hardened) secondary cell walls and are typically dead at maturity. They provide rigid support and protection to plant parts that have stopped growing. Sclerenchyma cells are found in the vascular tissues of plants, such as the xylem, where they contribute to the strength of stems and roots.

Skeletal Muscle: Attached to bones and responsible for voluntary movements.
Smooth Muscle: Found in the walls of internal organs like the digestive tract and blood vessels, responsible for involuntary movements.
Cardiac Muscle: Composes the heart and is responsible for pumping blood; it has characteristics of both skeletal and smooth muscle.
