What is the primary purpose of mitosis?

• To produce energy for cellular respiration.

• The primary purpose of mitosis is to enable cell division for growth and repair.

• To facilitate photosynthesis in plants.

• To enable the synthesis of proteins.

Describe the main stages of meiosis.

• Meiosis consists of one stage where chromosomes duplicate.

• Meiosis results in two diploid cells after one round of division.

• Meiosis involves three stages: Prophase, Metaphase, and Anaphase.

• Meiosis consists of two main stages: Meiosis I (homologous chromosomes separate) and Meiosis II (sister chromatids separate), resulting in four haploid gametes.

How does mitosis differ from meiosis in terms of genetic variation?

• Both mitosis and meiosis result in identical cells with no genetic variation.

• Mitosis produces identical cells with no genetic variation, while meiosis produces diverse gametes with genetic variation.

• Mitosis and meiosis both produce diverse cells with genetic variation.

• Mitosis creates gametes with genetic variation, while meiosis produces identical cells.

What are the phases of mitosis?

• Metaphase, Telophase, G1 phase, S phase

• Prophase, Anaphase, Cytokinesis, G2 phase

• Interphase, Cytokinesis, Synthesis, G1 phase

• Prophase, Metaphase, Anaphase, Telophase

Explain the significance of crossing over during meiosis.

• Crossing over decreases genetic diversity.

• Crossing over is irrelevant to chromosome segregation.

• Crossing over is significant because it increases genetic diversity and ensures proper segregation of chromosomes during meiosis.

• Crossing over occurs only in mitosis.

What is the end result of mitosis in terms of cell number and genetic identity?

• Two identical daughter cells with the same genetic identity as the parent cell.

• Two non-identical daughter cells with mutations.

• Four genetically diverse daughter cells.

• One identical daughter cell with half the genetic material.

How many times does DNA replicate during meiosis?

• 3 times

• 4 times

• 2 times

• 1 time

What role do spindle fibers play in mitosis?

• Spindle fibers form the nuclear envelope during cell division.

• Spindle fibers provide energy to the cell during mitosis.

• Spindle fibers are responsible for DNA replication.

• Spindle fibers help separate and move chromosomes during mitosis.

Define the term 'haploid' and its relevance to meiosis.

• Haploid cells are produced during mitosis.

• Haploid is a term used to describe diploid cells.

• Haploid is a cell with one set of chromosomes, relevant to meiosis as it results in the formation of gametes.

• Haploid refers to a cell with two sets of chromosomes.

What are the key differences in the outcomes of mitosis and meiosis?

• Mitosis produces 4 diverse cells; meiosis produces 2 identical cells.

• Mitosis produces 2 identical cells; meiosis produces 4 diverse cells.

• Mitosis and meiosis both produce 2 identical cells.

• Mitosis produces 4 identical cells; meiosis produces 2 diverse cells.
