Why is it advantageous for the antheridia and archegonia to be located on the underside of the prothallus?
It is advantageous for the antheridia and archegonia to be located on the ventral aspect of the fern. This keeps the genetalia closest to the rhizomes.
Are archegonia haploid or diploid?
Archegonia is diploid. Antheridia is haploid. They are found in bryophytes or 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.
Where are the antheridia and archegonia found in ferns?
the underside of the gametophyte
Are Antheridia present in conifers?
Yes.
Structure that holds antheridia and archegonia in ferns?
The antheridia and archegonia of a fern are located on the prothallus, which is heart-shaped. The prothallus is anchored to the soil by rhizoids.

It is advantageous for the antheridia and archegonia to be located on the ventral aspect of the fern. This keeps the genetalia closest to the rhizomes.
Are archegonia haploid or diploid?
Archegonia is diploid. Antheridia is haploid. They are found in bryophytes or ferns.
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?
Flowering Plants.
Where are the antheridia and archegonia found in ferns?
the underside of the gametophyte
Why don't archegonia and antheridia mature at the same time on a prothallus?
To avoid self-fertilisation which decreases genetic-diversity
Are Antheridia present in conifers?
Yes.
What are Female gametangia called?
Archegonia
Is a snapdragon monoecious or dioecious?
The gametophyte of the fern is monoecious since both the male and female sexual parts (termed antheridia and archegonia) are both on the same plant. I don't think there are any extant dioecious ferns.
What is the name of the female portion of a bryophyte?
Archegonia
