Mitosis and Cell Division Concepts

What are two main functions of mitosis in the human body?

• Producing reproductive cells and fighting infections

• Healing cuts and growing taller

• Digesting food and absorbing nutrients

• Creating new types of cells and storing energy

What kind of cells does mitosis primarily produce in the human body?

• Sperm and egg cells

• Body cells (somatic cells)

• Cells with half the genetic material

• Cells that are genetically different from each other

What is the genetic relationship between the new cells produced by mitosis and the original parent cell?

• The new cells are genetically unique from the parent cell.

• The new cells are genetically identical to the parent cell.

• The new cells have half the genetic material of the parent cell.

• The new cells have double the genetic material of the parent cell.

During the cell cycle, in which phase do cells spend most of their time growing, replicating DNA, and performing their normal functions?

• Mitosis

• Interphase

• Meiosis

• Cytokinesis

What important process happens during interphase, before mitosis begins?

• The cell divides into two new cells.

• Chromosomes line up in the middle of the cell.

• DNA is duplicated.

• New nuclei are formed around chromosomes.

How are chromosomes counted in a cell?

• By the number of chromatids present.

• By the number of centromeres present.

• By the total amount of DNA.

• By the number of sister chromatids.

Which of the following lists the stages of mitosis in the correct order?

• Metaphase, Prophase, Anaphase, Telophase

• Prophase, Anaphase, Metaphase, Telophase

• Prophase, Metaphase, Anaphase, Telophase

• Anaphase, Metaphase, Prophase, Telophase

What happens to sister chromatids during anaphase?

• They condense and become visible.

• They line up in the middle of the cell.

• They separate and move to opposite ends of the cell.

• New nuclei form around them.
