Question
A sporophyte produces _____.
Gametes
Spores
Zygote
None of the above
Gametes
Spores
Zygote
None of the above
Hint:
Diploid multicellular stage of a plant is sporophyte.
The correct answer is: Spores
Plants and algae undergo alteration of generation with alternating sporophyte and gametophytic generations.
Sporophyte refers to the diploid multicellular stage with two sets of chromosomes. This stage develops from the fusion of haploid cells.
Gametophytes refers to the haploid cells or gametes which fuse together to form a diploid zygote. This zygote develops into sporophytes.
The dominance of sporophyte or gametophyte generation depends upon the plant or algae.
- Alteration of generation depends upon plants
- Sporophyte is diploid multicellular stage
- Gametophyte is haploid
