Biology · SEXUAL REPRODUCTION IN FLOWERING PLANTS

हिन्दी

In some apomictic species, the diploid embryo develops without fertilisation because:

  1. The haploid egg cell is directly stimulated by pollen tube hormones.
  2. The diploid egg cell is formed without reduction division.
  3. Two haploid polar nuclei fuse to form the embryo.
  4. Synergid cells undergo meiosis and develop into an embryo.

Correct answer · Option 2

The diploid egg cell is formed without reduction division.

Explanation

In some apomictic species, the diploid egg cell is formed without reduction division (meiosis) and develops into the embryo without fertilisation.
