Answer:

Row (4): meiosis   meiosis   mitosis

Explanation:

There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. These germ cells suffer both mitosis (to form more sexual cells) and meiosis (giving place to haploid gametes, called sperm and egg cells, through the gametogenesis process). Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation.

Gametes´destiny is to merge in the process of fecundation, during which a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell from the structural point of view that suffer successive mitosis to form the new organism.

Meiosis and mitosis are both processes of cell division. Remember that

• Meiosis is a process by which, from a diploid germ cell (2n), four daughter cells with a haploid chromosome number (n) are produced. Each daughter cell has half of the chromosomes of the original one. There are two phases in meiosis: the first one in which occurs a chromosome´s reduction division, and the second one in which it occurs a new division, but this one is not a reductive one.

• Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the whole-cell first duplicates and then separates.

Related to the exposed chart in the problem:

- The formation of eggs and sperms occurs by the process of meiosis

- The growth of the embryo occurs by the process of mitosis after the egg and sperm merge and form the zygote.  

Answer 2

Based on the information given, the correct option is row 4: meiosis,   meiosis, and mitosis.

It should be noted that meiosis is the formation of egg and sperm cells.

On the other hand, mitosis is a process where a single cell divides into two identical daughter cells. During mitosis, one cell divides once to form two identical cells and the major purpose of mitosis is for growth and to replace worn out cells.
