Cell Division and Reproduction

What is the cell cycle?

• A regular sequence of growth and division that eukaryotic cells undergo.

• The time a cell spends actively dividing.

• The process of duplication of genetic material (DNA).

• Repeating process of DNA synthesis.

A human body cell has 46 chromosomes. After mitosis, how many chromosomes will the new cells have?

• 46

• 23

• 92

• 12

The final stage of the cell cycle in which the membrane-enclosed cytoplasm of the cell divides to form two daughter cells is called:

• prophase

• metaphase

• G1

• cytokinesis

Which phase of cell division does this picture show?

• prophase

• metaphase

• anaphase

• telophase

Which phase of cell division does this picture show?

• prophase

• metaphase

• anaphase

• telophase

Which type of cell division results in 4 genetically unique haploid (1/2 the number of chromosomes) cells?

• mitosis

• G1

• meiosis

• S

A form of reproduction in which there is one parent with identical offspring is called:

• sexual reproduction

• asexual reproduction

• mitosis

• meiosis

Offspring that are produced through sexual reproduction are usually similar, but never identical, to their parents. This is because:

• genes mutate during every occurrence of sexual reproduction

• all of the offspring's genes only come from one parent or the other

• genes are not transferred between parents and offspring during sexual reproduction

• half of the offspring's genes come from one parent while the other half comes from the other parent

Which of the following is an advantage of asexual reproduction?

• increases genetic variation

• often produces less offspring

• less time since no mate is required

• often takes longer for offspring to develop

Which part provides the pollen in this picture?

• stamen

• pistil
