11.2 The Process of Cell Division

What is the purpose of mitosis?

• To store genetic information

• To produce two identical daughter cells

• To repair damaged cells

• To break down nutrients

Explain the difference between mitosis and meiosis.

• Mitosis results in two identical daughter cells with the same number of chromosomes, while meiosis results in four genetically different daughter cells with half the number of chromosomes.

• Mitosis results in four genetically identical daughter cells with half the number of chromosomes.

• Mitosis results in two genetically different daughter cells with half the number of chromosomes.

• Meiosis results in two genetically different daughter cells with the same number of chromosomes.

Describe the stages of the cell cycle.

• Prophase, Metaphase, Telophase

• G1, G2, G3

• Anaphase, Cytokinesis, Interphase

• Interphase (G1, S, G2) and Mitotic phase (Prophase, Metaphase, Anaphase, Telophase)

What is the role of cytokinesis in cell division?

• Cytokinesis helps in DNA replication during cell division.

• Cytokinesis regulates the cell's metabolic activities.

• Cytokinesis divides the cytoplasm of a parent cell into two daughter cells.

• Cytokinesis determines the cell's shape after division.

What is the significance of chromosomes in cell division?

• Chromosomes are responsible for producing energy during cell division.

• Chromosomes are only present in plant cells during cell division.

• Chromosomes contain the genetic material that is replicated and distributed to daughter cells during cell division.

• Chromosomes are not involved in the process of cell division.

What are the main differences between mitosis and meiosis in terms of chromosome number?

• Mitosis reduces the chromosome number by half (n), while meiosis maintains the same chromosome number (2n).

• Mitosis and meiosis both reduce the chromosome number by half (n).

• Mitosis maintains the same chromosome number (2n), while meiosis reduces the chromosome number by half (n).

• Mitosis and meiosis both maintain the same chromosome number (2n).

What is the end result of meiosis?

• Two daughter cells with the same number of chromosomes

• Four daughter cells with half the number of chromosomes

• One daughter cell with the same number of chromosomes

• Eight daughter cells with double the number of chromosomes

Explain the concept of homologous chromosomes.

• Homologous chromosomes are pairs of chromosomes that have the same genes at the same loci but may have different alleles.

• Homologous chromosomes are unrelated pairs of chromosomes

• Homologous chromosomes have different genes at the same loci

• Homologous chromosomes do not play a role in genetic inheritance

What happens during the G1 phase of the cell cycle?

• Cell division

• DNA replication

• Mitosis

• Cell growth and normal function preparation
