Question

How does pollination lead to fertilisation? Explain

Answer 1

Answer:

• Pollination leads to fertilization in a flowering plant.
• During the sexual reproduction process, the male gametes and the female gametes of a flower need to come together for fertilization to take place.
• However, the ovules or anthers need external agents through pollination to move to each other.
• Pollinating agents like wind, water, and animals help to carry the anthers in the pollens to the ovules in the stigma for fertilization to take place.
• Some plants pollinate through self-pollination where the anthers and ovules of a single flower are pollinated within itself through agents like insects that come to drink its nectar.
• Other plants apply cross-pollination where the ovules and anthers from different plants of the same species get pollinated through agents like wind, water, or animals.

Answer 2

Explanation:

i) the male and female gametes fuse after fertilization

ii) the pollen grain transfer in the stigma with the help of pollination

iii) the pollen grain goes downward through the style.

iv) finally pollen grain enters in the ovary where male gametes fuse with egg and fertilization takes place

v) and zygotes form and developed into embryo
