Which of the following after fertilisation grows rapidly and ripens to form a fruit. Meanwhile, the petals, sepals, stamens, style and stigma may shrivel and fall off?

Correct option is B

• After fertilization, the ovary of the flower grows rapidly and ripens to form a fruit. During this process, the fertilized ovule (which becomes the seed) is encased within the developing fruit.
• As the fruit forms, other parts of the flower like the petals, sepals, stamens, style, and stigma may shrivel and fall off. The ovary wall, which forms the fruit, expands and matures to protect the seeds inside.
  

• Ovary: The ovary is the female reproductive organ of a flower that contains ovules. After fertilization, it develops into a fruit, while the ovules become seeds.

• Fruit Formation: As the ovary enlarges, it forms the fruit that houses the seeds. This is a key step in the reproductive cycle of angiosperms (flowering plants).

Additional Information:

• Ovule: The ovule becomes the seed after fertilization.

• Gynoecium: The gynoecium is the female reproductive part of the flower, consisting of the ovary, style, and stigma.

• Pistil: The pistil is the collective term for the gynoecium and includes the ovary, style, and stigma. It is involved in the fertilization process.
