Question

In which part of the flower does fertilisation occur?

• A. Ovary
• B. Anther
• C. Petals
• D. None of the above

Answer 1

The correct option is A

Ovary

The correct option is A:

Explanation of the correct option:

1. Fertilization is the process of haploid gametes, egg, and sperm fusing together to form a diploid zygote.
2. Pollination is a process that occurs in flowering plants to fertilise them.
3. When pollen grains from the anther fall on a stigma, the process of pollination begins.
4. When pollen grains land on the stigma of an appropriate flower, they form a tiny tubule that leads to the ovary via the style. The male gamete in the pollen grain meets the feminine gamete within the ovule, and fertilisation results in flowers.
5. A zygote is the cell that results from the fusing of gametes, and it develops into an embryo.
6. Each ovule grows into a seed after fertilisation, while the ovary develops into a fruit.

Explanation of the incorrect option:

Option B:

In seed plants, the anther is the male reproductive organ. Pollen production and dispersal are its primary functions.

Option C:

Petals are flowering plants' accessory organs. The most remarkable and conspicuous component of a flower is its petals. They are brilliantly coloured in order to attract pollinators. As a result, their role is to aid pollination while simultaneously safeguarding the inner set of critical whorls.

Final answer: Fertilisation occur in ovary of flowering plant.
