Understanding Cell Division: Mitosis and Meiosis

What is the primary goal of mitosis in cell division?

• To create two identical cells

• To initiate sexual reproduction

• To reduce the chromosome number by half

• To create two different cells

How does meiosis differ from mitosis in terms of the cells it produces?

• Meiosis produces two identical cells

• Meiosis produces four genetically diverse cells

• Meiosis does not involve chromosome duplication

• Meiosis results in cells with the same number of chromosomes as the original

During which phase of meiosis do homologous chromosomes exchange genetic material (a.k.a. crossing over)?

• Metaphase

• Prophase

• Anaphase

• Telophase

Why are haploid cells important for sexual reproduction?

• They are not involved in sexual reproduction

• They ensure genetic diversity

• They allow for the creation of diploid organisms

• They contain double the number of chromosomes

What is the diploid number of chromosomes in humans?

• 23 chromosomes

• 46 chromosomes

• 78 chromosomes

• 8 chromosomes

What is the result when a sperm and an egg combine?

• A haploid cell

• A somatic cell

• A diploid zygote

• A monoploid organism

What does the term 'haploid' signify in cell biology?

• Cells with no chromosomes

• Cells with a full set of chromosomes

• Cells with half the number of chromosomes

• Cells that can divide through mitosis

Which cells in the human body are considered diploid?

• All cells including sex cells

• Only sperm cells

• Only egg cells

• All cells except sex cells

How many chromosomes does a dog's somatic cell contain?

• 24 chromosomes

• 46 chromosomes

• 78 chromosomes

• 8 chromosomes

At what stage are females' eggs developed?

• Continuously from puberty

• Before birth

• During menopause

• After puberty
