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.

QUE SON LA BIOMOLECULAS​
DIA [1.3K]

Son consideradas biomoléculas aquellas moléculas que forman parte de los organismos vivos.  

Las moléculas son las unidades físicas de la materia, que se forman a partir de la unión de dos o más átomos agrupados a través de enlaces químicos.

Las biomoléculas se clasifican en inorgánicas u orgánicas.

• Las biomoléculas inorgánicas se encuentran ampliamente en la atmósfera. El agua, algunas sales como el cloruro de sodio, y gases como el oxígeno, son ejemplos de biomoléculas inorgánicas.  

• A las moléculas como azúcares, proteínas, combustibles, entre otras, las cuáles contienen átomos de carbono, hidrógeno, oxígeno y a veces nitrógeno se les llama moléculas orgánicas.

Cuando las moléculas orgánicas forman parte de la materia viva, se les conoce como biomoléculas orgánicas, las cuales incluyen fundamentalmente glúcidos, lípidos, proteínas y ácidos nucleicos.

Por lo tanto, podemos concluir que las moléculas (compuestos que se forman a partir de los elementos químicos) que se encuentran formando los seres vivos se conocen como biomoléculas y se clasifican en inorgánicas u orgánicas.
