what is the function of collenchyma and sclerenchyma?
Answers
Answer:
➡️➡️Collenchyma provides extra mechanical and structural support, particularly in regions of new growth.
➡️➡️ Sclerenchyma cells have thick lignified secondary walls and often die when mature. Sclerenchyma provides the main structural support to a plant.

Answer:
Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.
Sclerenchyma is a plant tissue providing mechanical stiffness and strength. Fibres and sclereids are the main types of sclerenchyma cells. Most sclerenchyma cells show intrusive growth. The cell walls of sclerenchyma have thickened secondary layers made from cellulose, hemicelluloses and lignin.
