Cell Division and Reproduction

Why do cells need to divide?

• in order to help the organism grow

• to replace damaged or dead cells

• to create new organisms

• all of these

What is the name of the process in which cells divide to create exact copies of themselves?

• mitosis

• photosynthesis

• meiosis

• reproduction

During the process of meiosis, how many times does the cell divide?

• once

• twice

• three times

• five or more times

What is uncoiled, stringy DNA called? (I called it an 'unwound' chromosome)

• chromatin

• chromosomes

• chlorophyll

• sister chromatids

Which of the following are true statements?

• DNA replicates during interphase

• Chromatin is made of DNA.

• Genes are found on DNA.

• All of the above

Why do organisms go through mitosis?

• To make more body cells, like skin cells or liver cells for example

• To make gametes (sperm or eggs)

• Just for fun!

• All of the above

Which of the following is the correct order of the phases of mitosis?

• Metaphase, Anaphase, Telophase, Prophase

• Prophase, Anaphase, Telophase, Metaphase

• Prophase, Metaphase, Anaphase, Telophase

• Interphase, Metaphase, Telophase, Prophase, Anaphase

What happens during Metaphase of mitosis?

• Chromosomes separate from one another

• Chromosomes line up single file down the middle of the cell

• Chromosomes become visible

• All of the above

What happens in Anaphase of mitosis?

• Sister chromatids separate and move towards opposite poles

• Chromosomes line up single file down the middle of the cell

• Nuclei re-form

• The nucleus disintegrates

What happens during Telophase of mitosis?

• Each newly forming cell gets a nucleus

• Chromosomes uncoil to form chromatin

• 2 diploid body cells are being formed

• All of the above
