Answer:

Here is the diagram of pollen grain

Answer 2

Structure of a pollen grain which is matured :

We identify a pollen grain that is mature by observing whether both vegetative as well as generative cells are present in it or not.

If both these cells, are present then we can identify the pollen grain that is mature. It is because a matured pollen grain consists both these cells.

The vegetative cell is larger and has reserved food substances. Also, it has a nucleus that do not have definite shape.

The generative cell is smaller and keeps on floating on the nucleus.
