Question

Which is the CORRECT statement regarding gametophytes?

  1. Haploid gametophyte produces diploid gametes.

  2. Diploid gametophyte produces diploid gametes.

  3. Haploid gametophyte produces haploid gametes.

  4. Diploid gametophyte produces haploid gametes.

hintHint:

The set of chromosomes present in egg or sperm.

The correct answer is:

Haploid gametophyte produces haploid gametes.


    The gametophyte is produced from the haploid spores formed during meiosis of sporophytes (2n)
    Gametophyte is multicellular sexual phase of plants and algae. The cells of gametophyte will contain only one set of chromosome (haploid).
    The gametophytes produces gametes which are haploid in nature.
    During sexual reproduction, the fusion of gametes will form a diploid zygote.

    • Sporophytes are diploid (2n)
    • Spores produced by meiosis are haploid (n)
    • Gametophytes are haploid (n)
    • Gametes formed will be haploid (n)
    • Zygote formed will be diploid (2n)
