Question

Sporophyte produce spores by the process of ________________.

  1. Mitosis

  2. Meiosis

  3. Both A and B

  4. None of the above

hintHint:

Haploid spores are produced.

The correct answer is:

Meiosis


    • Sporophytes are multicellular diploid phases in the lifecycle of plants and algae
    • Sporophytes undergo meiosis and produce spores
    • Spores are haploid in nature 
    • Haploid spores develop into gametophyte following mitosis
    • The multicellular gametophyte produces gametes 
    • Fertilization of gametes produces a diploid zygote
    • The zygote develops into multicellular sporophyte

    • Alteration of generation involves sporophyte and gametophytic phases
    • Plants and algae will undergo change between haploid and diploid stages 
    • The dominance of sporophyte and gametophytic phases depend on the type of the plant or algae
