Question
A gametophyte is __________ in nature.
Haploid
Diploid
Triploid
None of the above
Haploid
Diploid
Triploid
None of the above
Hint:
A diploid zygote is formed by the fusion of gametes.
The correct answer is: Haploid
In plants and algae, alteration of generation includes two stages: sporophyte and gametophyte. The two stages are also termed as asexual and sexual phases.
Sporophyte is the multicellular diploid stage of the plant. This forms the asexual phase. The meiosis of sporophyte produces haploid spores.
Gametophyte is the haploid multicellular stage that develops from the haploid spores. These form the sexual phase.
The haploid gametes fuse together to form diploid zygote.
- Sporophyte stage is also called asexual phase
- Gametophyte stage is also called sexual phase
