Which of the following is true about moss sporophytes?
a.
sporophytes perform photosynthesis.
c.
sporophyttes contain a single spore.
b.
sporophytes depend on the gametophyte for nutrients.
d.
sporophytes are very large.

Mosses are nonvascular seedless plants. Their life cycle has alternation of generation - a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid gametes which fuse to form a diploid zygote. The zygote grows into diploid sporophyte which produces haploid spores which grow. Sporophyte generation lasts very short and sporophytes depend on the gametophyte for nutrients.

Through the process of elimination:

- Sporophytes do not perform photosynthesis because they lack in chlorophyll unlike gametophytes.

- Sporophytes contain many spores.

- Sporophytes are small.

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.

hope this !
