front 1 what is the cell cycle? | back 1 The cell cycle, or cell-division cycle, is the series of events that take place in a eukaryotic cell between its formation and the moment it replicates itself. These events can be divided in two main parts: |
front 2 What are the stages of the cell cycle? | back 2 <ul> <li><strong>Growth (G1)</strong>: The cell grows and does its usual job.</li> <li><strong>Copy DNA (S)</strong>: The cell duplicates its DNA.</li> <li><strong>Preparation (G2)</strong>: The cell gets ready for division.</li> <li><strong>Division (M)</strong>: The cell divides into two new cells.</li> </ul> <br> |
front 3 What are the stages of mitosis? What is the main goal of mitosis? | back 3
The main goal of mitosis is to ensure that each daughter cell receives an identical set of chromosomes to the parent cell. This process ensures cell growth, tissue repair, and asexual reproduction. |
front 4 What is Cytokinesis? | back 4 cytokinesis which divides the cytoplasm and cell membrane. This results in two identical cells with an equal distribution of organelles and other cellular components. |
front 5 What is meiosis? What is the main goal of prophase 1 of Meiosis 1? | back 5 Meiosis is a special type of cell division for making reproductive cells (sperm and egg). In prophase I of meiosis I, the main goal is to mix up the genes to create genetic variety. During prophase I:

front 6 what type of cells does meiosis create? | back 6 Meiosis creates reproductive cells called gametes. In humans and many other organisms, gametes are sperm cells in males and egg cells (ova) in females |
front 7 Distinguish between meiosis and mitosis | back 7 <ul> <li>Purpose: <ul> <li><strong>Meiosis</strong>: Creates reproductive cells (gametes) for sexual reproduction, with half the number of chromosomes as the parent cell.</li> <li><strong>Mitosis</strong>: Produces identical copies of cells for growth, repair, and asexual reproduction, maintaining the same number of chromosomes as the parent cell.</li> </ul></li> <li>Number of Divisions: <ul> <li><strong>Meiosis</strong>: Two rounds of division (meiosis I and meiosis II), resulting in four daughter cells.</li> <li><strong>Mitosis</strong>: One round of division, resulting in two daughter cells.</li> </ul></li> </ul> <br> |
