Anthredia and archegonia
Where the eggs of gymnosperms and angiosperms are produced?

Why is it advantageous for the antheridia and archegonia to be located on the underside of the prothallus?

In Gymnosperm eggs are produced in the archegonia and in angiosperms in the embyo sac
The female reproductive structure of nonvascular plant is called?
archegonia.
What plants have a prothallus that forms archegonia and antheridia and has a dominant sporophyte?
ferns.
Do vascular plants produce antheridia and archegonia on the same gametophyte?
Only in those cases where spores are not differentiated into micro- & megaspores for developing the gametophytes. Thus homosporous vascular plants produce archegonia and antheridia on same gametophyte.
Which of the following plants has a prothallus that forms archegonia and antheridia and has a dominant sporophyte?
