It is basically explaining the reproductive processes of fungi,
With sexual rep. and how it requires 2 sex cells to unite to produce spores that grow into new organisms
and then at the conclusion it states that most fungi reproduce asexually ( by itself )
and an example of how.
Ribosomes make Protein for the cell.
A Sertoli cell (a kind of sustentacular cell) is a "nurse" cell of the testicles that is part of a seminiferous tubule and helps in the process of spermatogenesis; that is, the production of sperm.
It is activated by follicle-stimulating hormone (FSH) secreted by the adenohypophysis, and has FSH receptor on its membranes. It is specifically located in the convoluted seminiferous tubules (since this is the only place in the testes where the spermatozoa are produced). Development of Sertoli cells is directed by the testis-determining factor protein.
Answer:
It could be either B or C depending on if the males physically fight each other to get a mate or try to outperform and show-off more to gain a mate.
