Question

In a fern, the prothallus is the gametophyte true or false

Answer 1

Answer:

The correct answer is option True.

Explanation:

Ferns are the seedless tracheophytes belonging to group pteridophytes of the plant kingdom. The life cycle of a fern is divided into two phases: the haploid gametophytic stage and diploid sporophytic stage.  

The gametophyte is formed from the sporophytic spores after they are germinated on a suitable substratum. Sporophyte after germination forms a bisexual heart-shaped structure with no vascular tissues so uses rhizoids for attachment. This formed gametophyte is known as "prothallus".

Thus, the gametophyte structure is known as prothallus is true.

Answer 2

A prothallium, or prothallus is usually the gametophyte stage in the life of a fern or other pteridophyte. Occasionally the term is also used to describe the young gametophyte of a liverwort or peat moss as well.
