Question

Diagrammatically represent the process of germination of pollen on stigma and label the parts

Answer 1

Germination is the process by which an organism grows from a seed or similar structure. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. In addition, the growth of a sporeling from a spore, such as the spores of hyphae from fungal spores, is also germination. Thus, in a general sense, germination can be thought of as anything expanding into greater being from a small existence or germ.

Answer 2

Answer:

On the stigma, the pollen grains absorb water and nutrients and produce a tiny pollen tube that passes through the style and reaches the ovary. Then enlargement of the tube cell occurs which comes out of the pollen grain through a germ pore to form the pollen tube. The tube nucleus comes to the tip of the pollen tube.
