Delve into the complexities of mitosis and meiosis, unraveling their distinct roles in growth, repair, and reproduction. Discover the key events that orchestrate each stage, equipping yourself with a profound understanding of these cellular marvels.
Introduction
Mitosis and meiosis are two types of cell division that occur in eukaryotic cells. Mitosis is the process by which a cell divides into two identical daughter cells, while meiosis is the process by which a cell divides into four daughter cells, each with half the number of chromosomes as the parent cell.
Mitosis is used for growth and repair of tissues, while meiosis is used for the production of gametes (eggs and sperm). The key differences between mitosis and meiosis are summarized in the table below.
Stages of Mitosis
Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase. During prophase, the chromosomes become visible and the nuclear envelope breaks down. During metaphase, the chromosomes line up in the center of the cell. During anaphase, the chromosomes are separated and pulled to opposite ends of the cell.
During telophase, two new nuclear envelopes form around the chromosomes and the cell membrane pinches in the middle, dividing the cell into two daughter cells.
Stages of Meiosis: Comparing Mitosis And Meiosis Worksheet Answers Pdf
Meiosis consists of two rounds of division, called meiosis I and meiosis II. During meiosis I, the chromosomes are duplicated and then separated into two daughter cells. During meiosis II, the daughter cells from meiosis I are divided again, resulting in four daughter cells with half the number of chromosomes as the parent cell.
Comparison of Mitosis and Meiosis
The following table compares the key differences between mitosis and meiosis:
| Characteristic | Mitosis | Meiosis |
|---|---|---|
| Number of daughter cells | 2 | 4 |
| Chromosome number of daughter cells | Same as parent cell | Half the number of chromosomes as the parent cell |
| Purpose | Growth and repair of tissues | Production of gametes |
FAQs
What is the primary distinction between mitosis and meiosis?
Mitosis produces two genetically identical daughter cells, while meiosis results in four genetically diverse daughter cells.
How many chromosomes are present in daughter cells after mitosis?
Daughter cells produced by mitosis have the same number of chromosomes as the parent cell.
What is the significance of crossing over during meiosis?
Crossing over shuffles genetic material, promoting genetic diversity and adaptation.
