What is the importance of gametes? A. They help to produce proteins for the cell.
B. They are created when a cell splits into two copies of itself.
C. They engage in binary fission.
D. They allow eukaryotes to reproduce.

Explanation:

Gametes are also called sex cells.

There are two types: the sperm (male) and egg (female). Gametes are haploid or contain half of the genetic information. When they unite and fertilize, they combine the two halves of the genome to create a diploid zygote that has one complete set of genetic information.

This process is known as sexual reproduction, the type of reproduction that eukaryotes (organism with cells containing a nucleus with DNA and membrane bound organelles) typically use.

So, based on the information we know above, the best answer choice is D. They allow eukaryotes to reproduce

all eukaryotic cell have mitochondria : )
