How does mitotic cell division contribute to multicellular organism growth?

Question

a. It reduces the number of cells by dividing, allowing for more efficient resource use.

b. It alters the genetic materials in the cells, increasing diversity within tissues of the organism.

c. It increases the number of cells, contributing directly to the size and mass of an organism.

d. It produces cells with different genetic codes, so the organism can better adapt to environmental changes.

Answer 1

The correct answer is:

c. It increases the number of cells, contributing directly to the size and mass of an organism.

Mitotic cell division is the process by which a single cell divides to produce two genetically identical daughter cells. This process is essential for growth in multicellular organisms, as it results in an increase in cell number, which directly contributes to the overall size and mass of the organism.
