After fertilisation, which of the following develops a tough coat, is gradually converted into a seed and the zygote divides several times to form an embryo within it?

The Correct answer is Ovule.

Key Points

• After fertilisation, the ovule develops a tough outer coat known as the seed coat.
• The ovule is gradually converted into a seed, which contains the embryo formed by the repeated division of the zygote.
• The embryo is the future plant enclosed within the seed, surrounded by protective layers, aiding in its development under suitable conditions.
• The ovule contains the female gametophyte, which is fertilised by the male gametes during reproduction.
• Post fertilisation, the ovule undergoes changes such as the formation of the seed coat, storage of nutrients, and maturation into a functional seed.
• This process is crucial for the reproductive success of flowering plants, ensuring the dispersal and germination of the next generation.

 Additional Information

• Pistil
  • The pistil is the female reproductive organ of a flower, consisting of the stigma, style, and ovary.
  • Although it plays a role in reproduction, it is not directly converted into a seed.
  • The pistil facilitates the transfer of pollen to the ovary but does not form the embryo.
• Ovary
  • The ovary is the part of the pistil that contains one or more ovules.
  • Post fertilisation, the ovary develops into a fruit, enclosing the seeds.
  • While important in reproduction, the ovary itself does not become the seed.
• Gynoecium
  • The gynoecium refers collectively to the female reproductive structures in a flower, including pistils.
  • It is the overall organ system, not a specific part that develops into a seed.
  • Its primary function is to house and support fertilisation processes.
