1) The fundamental process by which a single cell divides into two or more daughter cells. a) Mitosis b) Cell Division c) Meiosis d) Gametes 2) What is the stage of mitosis where sister chromatids separate and move toward opposite poles of the cell? a) Prophase b) Anaphase c) Metaphase d) Telophase 3) The longest phase of meiosis, characterized by the pairing of homologous chromosomes (synapsis) and crossing over. a) Prophase 1 b) Metaphase 1 c) Telophase 1 d) Anaphase 1 4) How many daughter cells are produced, and what is their ploidy, after a single complete cycle of meiosis in a diploid parent cell? a) Four haploid (n) cells. b) Two haploid (n) cells. c) Two diploid (2n) cells. d) Four diploid (2n) cells. 5) The main goal of all cell division is to ensure that new cells receive a complete and correct set of: a) RNA b) DNA 6) Why is uncontrolled cell division a dangerous problem in the body?  a) It causes growths of tumors or cancers b) It stops all growth 7) The process of meiosis is essential for the continuation of life in sexually reproducing organisms because it ensures: a) The production of genetically identical clones. b) A permanent stop to cell division once maturity is reached. c) The maintenance of a stable chromosome number across generations. d) The constant production of new somatic (body) cells. 8) A person receives a deep cut that eventually heals. This healing process is primarily an example of which type of cell division, and why? a) Mitosis, ensuring identical cells for tissue replacement and repair. b) Meiosis, to allow for new genetic combinations in the repaired area. c) Meiosis II, to separate sister chromatids for quick cell production. d) Mitosis, to create haploid cells that can fuse quickly. 9) The formation of a cell plate in plant cells or a cleavage furrow in animal cells marks the final step of which phase of the cell cycle? a) Interphase b) Cytokinesis c) Karyokinesis d) Prophase 10) If a parent cell has 24 chromosomes (2n=24), how many chromosomes will each daughter cell have immediately after mitosis and cytokinesis are complete? a) 6 chromosomes b) 48 chromosomes c) 12 chromosomes d) 24 chromosomes 11) Which sequence correctly represents the stages of mitosis? a) Metaphase, Prophase, Anaphase, Telophase b) Prophase, Metaphase, Anaphase, Telophase c) Interphase, Prophase, Metaphase, Anaphase d) Prophase, Anaphase, Metaphase, Telophase 12) Which type of cell division is like a photocopier, making two exact copies of the original cell? a) Meiosis b) Mitosis 13) Protein structures that form during cell division and are involved in moving and segregating chromosomes. a) Chromatid b) Centromere c) Spindle Fiber d) Gametes 14) What is the term for the tiny, thread-like structures inside the cell's nucleus that carry your genes? a) Nuclei b) Chromosomes  15) The process of cell division that makes sperm i make and egg cells in females is called a) Meiosis b) Photosynthesis
