Answer 1

when pollen grains are transfered from the d anther to d stigma pollination do takes place which is then responsible for fertilisation
ovule - seed
ovary- fruit

Answer 2

Let me give this a try;

• Fertilization is the transfer of pollen grains from the anthers of the male to  the stigma of the female for their fusion. If this transfer occurs on the same plant it is called self pollination, but if occurs on different pants its called cross pollination.
• The part that develops to the seed is the ovule while the part develops to fruits the ovary.
