Many singlecelled eukaryotic organisms have evolved complex

Many single-celled eukaryotic organisms have evolved complex life cycles that include sexual reproduction. This means that:

Question 5 options:

diploid cells must undergo mitotic cell division in order to reproduce.

at some point, two cells must fuse to become diploid.

haploid cells must undergo meiotic divisions to form gametes.

complex mating behaviors likely evolved at the same time as sexual reproduction.

Solution

at some point, two cells must fuse to become diploid.

Many single-celled eukaryotic organisms have evolved complex life cycles that include sexual reproduction, this means that they at some point will produce haploid cells and the fusion of the same would produce a zygote
