Question

The given figure shows two phases, A and B of a typical angiospermic life cycle. Select the correct option regarding it.

• A.

  A	B
  Gametophytic generation (n)	Sporophytic generation (2n)

• B.

  A	B
  Sporophytic generation (2n)	Gametophytic generation (n)

• C.

  A	B
  Sporophytic generation (n)	Gametophytic generation (2n)

• D.

  A	B
  Gametophytic generation (n)	Sporophytic generation (n)

Answer 1

The correct option is A

A	B
Gametophytic generation (n)	Sporophytic generation (2n)

A - Gametophytic generation (n)
B - Sporophytic generation (2n)

In angisperms, the gametophytes are haploid (n) structures such as the pollen grain and the egg cell that act as gametes and fertilise to form a zygote which marks the beginning of the sporophytic generation. Sporophytes are diploid (2n), i.e., they have two sets of chromosomes and form the dominant plant body.
