Mitosis and Meiosis
Mitosis and meiosis are essential processes of cell division that enable organisms to grow, repair tissues, and reproduce. While mitosis produces genetically identical cells for growth and maintenance, meiosis creates genetically unique reproductive cells that are necessary for sexual reproduction. Understanding these processes is fundamental to learning genetics, inheritance, and the life cycle of living organisms. This flashcard deck covers the key concepts of mitosis and meiosis, including the cell cycle, interphase, the stages of mitosis (prophase, metaphase, anaphase, and telophase), cytokinesis, meiosis I and meiosis II, chromosome number, homologous chromosomes, crossing over, independent assortment, and the major differences between mitosis and meiosis. It also explains how meiosis contributes to genetic variation and why accurate chromosome separation is essential for healthy cell division. Designed for biology students and lifelong learners, these flashcards present important concepts in a clear question-and-answer format that supports active learning and long-term retention. Whether you are studying for quizzes, preparing for biology exams, or reviewing the fundamentals of cell division, this deck provides an effective way to strengthen your understanding of mitosis, meiosis, and the biological processes that support growth, reproduction, and heredity.
All Cards in This Deck
Question
What is the purpose of the cell cycle?
Answer
The cell cycle allows cells to grow, replicate their DNA, and divide to produce new cells.
Question
What is mitosis?
Answer
Mitosis is the process of nuclear division that produces two genetically identical daughter cells.
Question
What is the primary purpose of mitosis?
Answer
Mitosis supports growth, tissue repair, and asexual reproduction.
Question
How many daughter cells are produced by mitosis?
Answer
Two daughter cells.
Question
What is meiosis?
Answer
Meiosis is a specialized type of cell division that produces haploid gametes for sexual reproduction.
Question
How many daughter cells are produced by meiosis?
Answer
Four daughter cells.
Question
What is the chromosome number of cells produced by meiosis?
Answer
They are haploid, containing half the number of chromosomes as the parent cell.
Question
What happens during interphase before cell division?
Answer
The cell grows, performs normal functions, and replicates its DNA.
Question
What occurs during prophase of mitosis?
Answer
Chromosomes condense, the nuclear envelope breaks down, and the spindle apparatus begins to form.
Question
What happens during metaphase of mitosis?
Answer
Chromosomes align at the cell's equator (metaphase plate).
Question
What occurs during anaphase of mitosis?
Answer
Sister chromatids separate and move toward opposite poles of the cell.
Question
What happens during telophase of mitosis?
Answer
New nuclear envelopes form around each set of chromosomes, and the chromosomes begin to decondense.
Question
What is cytokinesis?
Answer
Cytokinesis is the division of the cytoplasm that separates one cell into two daughter cells.
Question
What is the main purpose of meiosis I?
Answer
Meiosis I separates homologous chromosomes, reducing the chromosome number by half.
Question
What is the main purpose of meiosis II?
Answer
Meiosis II separates sister chromatids into individual cells.
Question
What is crossing over?
Answer
Crossing over is the exchange of genetic material between homologous chromosomes during prophase I of meiosis.
Question
Why is crossing over important?
Answer
It increases genetic variation among offspring.
Question
What is independent assortment?
Answer
Independent assortment is the random distribution of homologous chromosome pairs into gametes during meiosis I.
Question
What is the main difference between mitosis and meiosis?
Answer
Mitosis produces two genetically identical diploid cells, while meiosis produces four genetically diverse haploid cells.
Question
Why is meiosis essential for sexual reproduction?
Answer
It produces haploid gametes, ensuring the chromosome number is restored when fertilization occurs.
