• metaphase
• mitosis

Identify the phase of mitosis shown

• prophase

• metaphase

• anaphase

• telophase

Which phase comes NEXT?

• prophase
• metaphase
• anaphase
• telophase

Which is Metaphase?

• A
• E
• C
• F

What is this phase of mitosis?

• prophase
• metaphase
• anaphase
• telophase

Which of the following describes the purpose of the mitotic cell division?

• To make more of the same cells.

• For growth and repair.

• To prevent the cell from becoming too large.

• All of the above.

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.

If a somatic (body) cell in a butterfly contains 24 chromosomes, a butterfly egg would contain

• 3

• 6

• 12

• 24

Meiotic cell division makes sperm and egg cells. In humans, sperms and ova each have _____ chromosomes. Therefore a fertilized egg would create a cell with _____ chromosomes.

• 23, 46

• 46, 23

• 2, 4

• 50, 100

What is the cell cycle?

• The gradual development of something, especially from a simple to a more complex form.
• The study of heredity and the variation of inherited characteristics.
• The branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
• The series of events that take place in a cell leading to its division and duplication of its DNA to produce two daughter cells.
