Class 11 Botany simulations · Plant Kingdom

Alternation of generations

Follow plant life cycles round the loop of haploid (n) and diploid (2n) phases. Compare which phase dominates.

Open the simulation

What to notice

Haplontic cycles have only a one-celled diploid zygote; diplontic cycles have only a few-celled haploid stage.

Key relation

2n sporophyte —meiosis→ n spores → n gametophyte —gametes, syngamy→ 2n zygote

Try this

Compare bryophytes with pteridophytes — which generation is the main plant body in each?

What you can change

• Life cycle: choose Haplontic, Diplontic, Haplo-diplontic: bryophytes, Haplo-diplontic: pteridophytes
