PPT-Introduction to the Cell Cycle

Why do cells need to divide As cells grow larger they start to face several difficulties in functioning Growth amp Repair In order for multicellular organisms to grow cells must divide If cells are lost due to injury or damage to DNA .

During which phase does the size of the cell increase?. Identify and restate what the phases of the eukaryotic cell cycle are.. Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. The Mitosis Puzzle. Lay blank sheet lengthwise .. Write Interphase, Prophase, Metaphase, Anaphase, & . Telophase. across the top of the sheet.. Cut out the cell diagrams and tape/glue them across the top under the appropriate phase label.. . During the cell cycle, a cell grows, prepares for division, and divides to form two identical daughter cells, each. of which then begins the cycle again.. The series of events that cells go through as they grow and divide.. Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. Variation of length of cell cycle. In humans, the frequency of cell turnover . varies. E. arly embryonic development. (Few hours ). E. pithelial cells (2-5 days). Specialized cells. (. cortical neurons or cardiac muscle cells. Unit 1 – Cells and Proteins. Advanced Higher Biology. Miss Aitken. Why is controlling the cycle important?. Complex events must work perfectly to produce new daughter cells. Mutations can occur if events do not go to plan. It is the growth and division of single cell into daughter cells and duplication (replication).. In . prokaryotic cells, . the cell cycle occurs via process termed binary fission.. In . eukaryotic cells, .
