Question

What is the function of intine in pollen grain?

Answer 1

Intine:

1. Pollen grains are a clump of microspores found in seeded plants that appear as fine dust.
2. Cellulose and pectin make up the inner, less rigid layer of the pollen grain, known as intine.
3. It is crucial for the maturation of pollen grains and the germination of pollen tubes.
4. Microspore cytoplasm aids in the formation of the intine layer.
