Question:
When and where does reduction division take place in the life cycle of a liverwort, a moss, a fern, a gymnosperm and an angiosperm?
Answer:
Reduction division (meiosis) occurs during spore formation:
- Liverwort and moss: in the sporangium of the sporophyte.
- Fern: in the sporangia (on sporophylls) of the sporophyte.
- Gymnosperm: in microsporangia (pollen mother cells) and megasporangia (ovule) of the sporophyte.
- Angiosperm: in pollen mother cells (microspore formation) and megasporocyte/ovule (megaspore formation) of the sporophyte.
