Question

1.Some features of Haplontic and Diplontic life cycles are given below.
Arrange them correctly in a table
1) Sporophyte is a single celled zygote.
2) Meiosis occurs in zygote.
3) Sporophyte dominant
4) No free living sporophyte.
5) Gametophyte dominant
6) Meiosis occurs before zygote formation . ​

Answer 1

Answer:

Haplontic cycle Diplontic Cycle

1) The zygote undergoes meiosis and gametophyte is a dominant phase. 1) Gametes undergo meiosis and diploid sporophyte is the dominant and independent phase.

2) The sporophytic phase is represented by single-celled zygote called as zygospores. 2) Gametes are haploid and called a gametophyte.

3) Haploid spores are formed by meiosis in a zygote. 3)The sporophyte is conspicuous.

4) Each spore on favourable condition forms a gametophyte. 4) In angiosperms stamens and ovaries contain sporophytes

5) It is observed in algae like volvox, spirogyra etc. 5) Present in angiosperms and gymnosperms
