Pollination and Fertilization

Q1: What is pollination?

Answer:

The transfer of the pollen grains from the male reproductive organ (anther) to the female reproductive organ (stigma) of the flowers in angiosperms (flowering plants) to the ovule in gymnosperms (non-flowering plants) is called pollination.

Q2: What is the mechanism of Fertilization?

Answer:

Pollen tube growth or direct pollen-ovule contact

Q3: What are the characteristics of pollination?

Answer:

1. Pollination occurs through various mechanisms including wind, water, insects, birds, and other animals.
2. It is an important phase in plant reproduction as the male gametes which are sperm can be transferred to the female gametes (eggs).
3. Self-pollination (means transfer of pollens within the same flower or same flower of a similar plant) and cross-pollination (means transfer of pollen between flowers of different plants) are the two types of pollination.

Q4: What is the objective of pollination?

Answer:

To deliver pollen to female reproductive organs.

Q5: What is Fertilization?

Answer:

Fertilization is the process of male and female gametes which are resulting in zygote formation. It can be developed into an embryo and eventually a new individual.

Difference Between Pollination and Fertilization: Pollination is the transfer of pollen grains from the male reproductive organ (anther) to the female reproductive organ (stigma) in a flower resulting in the formation of seeds. It is primarily carried out by various agents like wind, water, insects, birds, or other animals.
