Question 6

What is sorus? sori-plural

Answer 6

a cluster of spore-producing receptacles on the underside of a fern frond

Question 7

The cycle of pteridophytes (ferns)

Answer 7

The diploid generation is the sporophyte which produces the spores. The plant produces spores which are carried away by wind to far off places. Under favourable conditions these spores germinate into small independent gametophytes called prothallus.

The haploid generation is the gametophyte which produces the gametes.

Gamatophytes are multicellular and photosynthetic.

They bear male and female sex organs.

The sperm fuses with the egg resulting in the formation of zygote.

The zygote later develops into a multicellular sporophyte.
