Meiosis and Mitosis

During which phase of the meiotic cell cycle does DNA replication occur?

• Interphase
• Prophase
• Metaphase
• Anaphase

A plant's diploid cells normally contain 24 chromosomes. How many chromosomes will be present in the plant's haploid cells?

• 48

Which cell is undergoing meiosis?

• cell 3
• cell 4
• cell 1
• cell 2

In multicellular organisms, some cells undergo meiotic division and produce haploid cells. This helps maintain a constant number of chromosomes over successive generations. Which cells are haploid cells?

• Egg cell

• Liver cell

• Nerve cell

• Sperm Cell

• Epithelial cell

Upon completion of the stage in the figure, what step will occur next?

• nuclear envelopes will form around the chromosomes

• chromosomes will become aligned in the center of the cell

• the homologous chromosomes will separate

• spindle fibers will attach to homologous chromosomes

A tomato plant cell has 24 chromosomes. How many chromosomes will each daughter cell have after the cell undergoes a mitotic division?

The process of mitosis ensures that each daughter cell has a copy of every chromosome present in the parent cell. Which is the purpose of this process? (SELECT ALL THAT APPLY)

• It creates reproductive cells

• It helps each new cell perform the same function

• It helps replace old, worn out cells

• It helps in multiplication of DNA

Students were learning about the cell reproduction cycles of mitosis and meiosis. Which process creates two identical new cells?

• mitosis

• meiosis
