Question 1

What is the growing stage of a cell called

Answer 1

Interphase

Question 2

What is the division stage of a cell called

Answer 2

Mitosis

Question 3

What stage is most of the cells life spent in

Answer 3

Interphase

Question 4

What is mitosis

Answer 4

The process of cell division to create genetically identical cells

Question 5

Why do cells need to undergo mitosis

Answer 5

For growth, to repair or replace damaged cells, reproduction of an organism

Question 6

What is interphase

Answer 6

The cell grows and carries out its normal functions, it make a copy of its organelles, makes a copy of its DNA to prepare for division

Question 7

What is prophase

Answer 7

The nuclear membrane begins to disappear, the DNA condenses into chromosomes that are visible under the microscope (since it was duplicated in interphase, 2 identical copies are joined together)

Question 8

What is metaphase

Answer 8

Spindle fibers in the cytoplasm attach to the duplicated chromosomes, chromosomes line up at the middle of the cell

Question 9

What is anaphase

Answer 9

Duplicated chromosomes are pulled apart by the spindle, separating the identical copies of DNA, each part is not called a chromatid(or single chromosome)

Question 10

What is telophase

Answer 10

Each nucleus now has a complete set of chromosomes, new nuclear membranes begin to form around the chromosomes, the chromosomes begin to uncoil

Question 11

What is cytokinesis

Answer 11

Part of telophase, pinches and divides the cytoplasm into two parts, two identical cells are formed (if plant cell, cell plate is formed in between the two cells instead)
