Alternation of Generation in plants | Sporophyte vs gametophyte

Alternation of Generation in plants | Sporophyte vs gametophyte#Reproduction
Alternation of generations is a life cycle phenomenon in plants, where two distinct generations alternate with each other:
1. Gametophyte generation (n): Produces gametes (sex cells) and is typically haploid (has one set of chromosomes).
2. Sporophyte generation(2n): Produces spores and is typically diploid (has two sets of chromosomes).
This cycle is common in plants, including:
1. Ferns
2. Mosses
3. Liverworts
4. Hornworts
5. Conifers
6. Flowering plants
The cycle goes like this:
1. Gametophyte (n) → produces gametes (sperm or egg cells)
2. Fertilization → forms a zygote (2n)
3. Zygote develops into a sporophyte (2n)
4. Sporophyte produces spores (n)
5. Spores germinate into a new gametophyte (n)
This alternation of generations allows plants to alternate between sexual and asexual reproduction, promoting genetic diversity and adaptation.
