Mitosis Meiosis Flashcards
What is mitosis?
Mitosis is the process of cell division that results in two genetically identical daughter cells.
What is meiosis?
Meiosis is the process of cell division that results in four genetically diverse daughter cells, each with half the number of chromosomes.
True or False: Mitosis occurs in somatic cells.
True
True or False: Meiosis results in diploid cells.
False
What are the phases of mitosis?
The phases of mitosis are prophase, metaphase, anaphase, and telophase.
What is the primary purpose of mitosis?
The primary purpose of mitosis is to enable growth and repair in multicellular organisms.
Fill in the blank: During meiosis, _____ occurs, which increases genetic variation.
crossing over
What is the end result of meiosis?
The end result of meiosis is four haploid gametes.
What is the difference between haploid and diploid cells?
Haploid cells contain one set of chromosomes, while diploid cells contain two sets.
What type of cells undergo meiosis?
Germ cells undergo meiosis.
True or False: Mitosis produces four cells.
False
What is the role of spindle fibers in mitosis?
Spindle fibers help separate the chromosomes during cell division.
What is the term for the physical division of the cytoplasm during cell division?
Cytokinesis
Multiple Choice: In which phase of mitosis do chromosomes line up in the center of the cell? A) Prophase B) Metaphase C) Anaphase D) Telophase
B) Metaphase
What is the significance of meiosis in sexual reproduction?
Meiosis generates genetic diversity and reduces chromosome number for gametes.
Fill in the blank: The first division in meiosis is called _____ division.
reductional
What happens during prophase I of meiosis?
Homologous chromosomes pair up and crossing over occurs.
True or False: Mitosis is essential for asexual reproduction.
True
What is the outcome of a cell undergoing mitosis?
The outcome is two genetically identical diploid cells.
What is the role of checkpoints in the cell cycle?
Checkpoints ensure that the cell is ready to proceed to the next stage of division.
What is an example of a diploid organism?
Humans are an example of a diploid organism.
Multiple Choice: Which phase of meiosis is characterized by the separation of homologous chromosomes? A) Metaphase I B) Anaphase I C) Telophase I D) Prophase II
B) Anaphase I
What is the difference between meiosis I and meiosis II?
Meiosis I separates homologous chromosomes, while meiosis II separates sister chromatids.
True or False: Cytokinesis occurs after both mitosis and meiosis.
True
