cell dicision

Question 1

What type of cell division produces 2 genetically identical cells?

Answer 1

Mitosis

Mitosis results in daughter cells with the same number of chromosomes as the original cell.

Question 2

What is the purpose of mitosis?

Answer 2

• Make new cells for growth of the body
• Make new cells to replace damaged cells
• Make new cells to replace worn out cells

Mitosis is essential for growth and repair in organisms.

Question 3

In mitosis, how many chromosomes do the new daughter cells contain compared to the original cell?

Answer 3

The same number of chromosomes

For humans, this means daughter cells contain 46 chromosomes.

Question 4

What type of cell division produces 4 genetically different gametes?

Answer 4

Meiosis

Meiosis results in gametes that are genetically unique.

Question 5

How many chromosomes do the gametes produced in meiosis contain?

Answer 5

Half the normal number of chromosomes

In humans, gametes contain 23 chromosomes.

Question 6

What is the result of meiosis?

Answer 6

Four gametes (sex cells)

Each gamete contains only one of each pair of chromosomes.

Question 7

Fill in the blank: Mitosis produces _______ genetically identical cells.

Answer 7

2

Question 8

Fill in the blank: Meiosis produces _______ genetically different gametes.

Answer 8

4

Question 9

True or False: Mitosis results in cells that are genetically different from the original cell.

Answer 9

False

Mitosis produces genetically identical cells.

Question 10

True or False: Each gamete produced in meiosis contains two of each pair of chromosomes.

Answer 10

False

Each gamete contains only one of each pair of chromosomes.
