8th Grade Mod A Unit 2 Lessons 1 & 2 Review

How does a sex cell differ from a body cell?

• A sex cell does not contain chromosomes.

• A sex cell contains homologous chromosomes.

• A sex cell has the same number of chromosomes as a body cell.

• A sex cell has half the amount of genetic material as a body cell.

Amanda is making a poster to describe the two types of cell division. She draws an outline of a human body on the poster. Amanda wants to show diagrams of mitosis and meiosis zooming out from the different parts of the body where they take place. Which of these choices correctly shows a location for a type of cell division?

• bone—meiosis

• testes—mitosis

• ovaries—meiosis

• stomach—meiosis

How is meiosis related to sexual reproduction?

• Meiosis allows the offspring produced during sexual reproduction to grow and develop.

• Meiosis joins together the sex cells during sexual reproduction to produce new offspring.

• Meiosis produces the sex cells that join to form new offspring during sexual reproduction.

• Meiosis produces the body cells that join to form new offspring during sexual reproduction.

In what way is cell division important to keeping organisms healthy?

• Cell division makes specialized cells.

• Cell division causes cells to grow larger.

• Cell division replaces damaged cells with new cells.

• Cell division is not part of keeping organisms healthy.

How does a multicellular organism grow larger?

• Multicellular organisms do not grow larger.

• Individual cells in the organism grow larger.

• The organism gains new cells from other organisms.

• Cells in the organism divide, increasing the total number of cells.

Terrell uses a microscope to look at slides of plant cells. He sees a cell with two nuclei that have visible chromosomes. In which stage of cell division is this cell?

• anaphase

• prophase

• telophase

• interphase

Which of these phases of mitosis takes place first?

• anaphase

• telophase

• prophase

• metaphase

Alla uses a microscope to look at slides of onion cells. The slides show the stages of the cell cycle. The slides are labeled and in the correct order, starting with interphase. In which slide would Alla first see chromosomes?

• anaphase

• prophase

• telophase

• cytokinesis

Which of these statements most likely describes what happens if DNA is not duplicated during interphase?

• The new cells would be more numerous.

• The new cells would have too many chromosomes.

• The new cells would have too many or too few nuclei.

• The new cells would have an incorrect number of chromosomes.
