Question
The gametophyte in alternation generation is described by which of the following:
Diploid generation
Spore producing generation
Gamete producing generation
All of the above
Diploid generation
Spore producing generation
Gamete producing generation
All of the above
Hint:
Sex cells are produced by gametophytes.
The correct answer is: Gamete producing generation
Sporophyte and gametophyte are two phases in the life cycle of a plant or algae. 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 gametophyte will produce haploid gametes for sexual reproduction.
The haploid gametes undergo fertilization and produce a diploid zygote.
- Sporophyte stage is also called asexual phase
- Gametophyte stage is also called sexual phase
