Cell Division

What is the cell cycle?

• 
• A process of photosynthesis in plants

• A method of cellular respiration

• A type of genetic mutation

What occurs during prophase?

• Chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

• Chromosomes align at the cell's equator and the nuclear envelope remains intact.

• The cell undergoes cytokinesis and the cytoplasm divides into two daughter cells.

• Chromatin is replicated and the cell prepares for DNA synthesis.

What is the significance of the G1 phase?

• It is the stage where the cell divides into two daughter cells.

• It is the first stage of interphase where the cell grows, synthesizes proteins, and prepares for DNA replication.

• It is the phase where DNA is replicated before cell division.

• It is the stage where the cell undergoes apoptosis.

What occurs during the S phase of the cell cycle?

• DNA replication occurs, resulting in the duplication of chromosomes.

• Cell division occurs, resulting in two daughter cells.

• Protein synthesis occurs, leading to cell growth.

• Chromosome segregation occurs, preparing for mitosis.

What is the difference between mitosis and meiosis?

• Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse gametes.

• Mitosis occurs in somatic cells, while meiosis occurs in prokaryotic cells.

• Mitosis produces four identical daughter cells, while meiosis results in two genetically diverse gametes.

• Mitosis and meiosis are identical processes that produce the same number of cells.

What is cytokinesis?

• The process of DNA replication during cell division.

• The division of the cytoplasm of a parental cell into two daughter cells.

• The formation of the nuclear envelope during mitosis.

• The synthesis of proteins in the ribosomes.

What happens during metaphase?

• Chromosomes align at the cell's equatorial plane and are attached to spindle fibers.

• Chromosomes are replicated and begin to condense.

• The nuclear envelope breaks down and spindle fibers begin to form.

• Chromosomes are pulled apart to opposite poles of the cell.

What is anaphase?

• The stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

• The phase of cell division where DNA is replicated.

• The process of cell division that results in two identical daughter cells.

• The stage of mitosis where chromosomes align at the cell's equator.

What is the purpose of checkpoints in the cell cycle?

• To regulate the speed of cell division

• To ensure proper progression of the cell cycle and prevent errors such as DNA damage.

• To promote apoptosis in damaged cells

• To facilitate nutrient absorption during cell growth.

What is the difference between haploid and diploid cells?

• Haploid cells contain two sets of chromosomes (2n), while diploid cells contain one set of chromosomes (n).

• Haploid cells contain one set of chromosomes (n), while diploid cells contain two sets of chromosomes (2n).

• Haploid cells are found in somatic cells, while diploid cells are found in gametes.

• Haploid cells are larger than diploid cells.
