Metaphase

Question 13

What is the proper sequence for the phases of mitosis?

Answer 13

Prophase, metaphase, anaphase, telophase

Question 14

What is the role of the spindle during mitosis?

Answer 14

It helps separate the chromosomes

Question 15

The two main stages of cell division are called

Answer 15

Mitosis and cytokinesis

Question 16

One difference between cell division in plant cells and animal cells is that plant cells have

Answer 16

A cell plate

Question 17

During normal mitotic cell division, a parent cell having four chromosomes will produce two daughter cells, each containing

Answer 17

Four chromosomes

Question 18

Right after a bone breaks, cells at the edge of the injury

Answer 18

Begin to divide rapidly

Question 19

Cells grown in a petri dish tend to divide until they form a thin layer covering the bottom of the dish. If cells are removed from the middle of the dish, the cells bordering the open space will begin dividing until they have filled the empty space. What does this experiment show?

Answer 19

The controls on cell growth and division can be turned on and off
