Meiosis
What type of cell is produced by meiosis?
Gametes
What is the main purpose of mitosis?
To make two identical daughter cells for growth or to replace damaged cells.
What is the final step of cell division where the cytoplasm divides to form two cells?
Cytokinesis
During which phase of meiosis does homologous recombination (crossing over) occur?
Prophase I.
During which stage of mitosis do the chromosomes line up in the middle of the cell?
Metaphase.
What are the two cell cycle?
Mitosis and Meiosis
What is the result of meiosis in terms of chromosome number in daughter cells?
The chromosome number is halved, producing haploid cells (n).
What happens to the chromosomes during Anaphase of mitosis?
The sister chromatids are pulled apart to opposite sides of the cell.
During which phase of the cell cycle does the cell grow and prepare for division?
Interphase
What happens during Anaphase I of meiosis?
Homologous chromosomes (pairs) are pulled to opposite sides of the cell.
How is telophase in mitosis different from telophase in meiosis?
In mitosis, the cell splits into two identical cells; in meiosis, the result is four different, haploid cells.
What happens if the cell cycle goes wrong and the cell divides uncontrollably?
It can lead to cancer, where cells grow and divide too quickly.
Why is meiosis important for sexual reproduction?
Meiosis creates gametes with half the number of chromosomes, so when a sperm and egg join, the offspring has the correct number of chromosomes.
How does mitosis ensure that each daughter cell gets the same number of chromosomes as the parent cell?
Mitosis carefully copies the chromosomes in the parent cell and divides them evenly so that each daughter cell has the same set of chromosomes.
