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

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.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
