Question

2. With the help of a diagram explain how pollination leads to fertilization. ​

Answer 1

Explanation:

The process of transfer of pollen grains from anther to the stigma of the flower of a plant of same species is known as pollination. The fusion of male and female gametes take place only after pollination.

The pollen grains are deposited on the stigma by pollination. The pollen grains germinate on stigma producing a tube known as pollen tube. The pollen tube grows downward into the style and reaches to ovary. Finally it enters into the ovule through a minute pore. Here one male gamete fuses with egg. It is the act of actual fertilization by which production of zygote and development of embryo take place.

Answer 2

Answer:

first the bees or the butterflies, who so ever the carrier is approaches toward a flower to drink nectar as it gets attracted, then the pollens stick to the carries and when the carrier brushes past another flower, the pollens then stick to the stigma. from there the pollen tube takes the pollen into the ovary where it fuses with the female gamete to form a zygote.

later under the further development, the eggs form seed and the flower turns out to become a fruit. the sepals and petals fall out.
