PPT-The Cell Cycle

Section 51 1 Objectives SWBAT describe the stages of the cell cycle SWBAT compare rates of division in different types of cells SWBAT identify factors that limit cell size 2 Starter Why do you always have to cut your hair your fingernails and the lawn. Cell Increase and Decrease. Cell division increases the number of somatic cells. Consists of mitosis (division of the nucleus) and cytokinesis (division of the cytoplasm). Apoptosis, programmed cell death, decreases the number of cells. Why do cells need to divide?. Growth and development. You started as 1 cell and now you’re made up of roughly 40 TRILLION cells. Repair and regeneration of tissue. Reproduction. What happens when cells divide? . Just like people have phases of development,. Cells have phases too.. In somatic (body) cells, a parent cell produces 2 daughter cells.. The purpose of mitosis is for growth and repair of tissue.. Three Phases or Stages. simpler. Ex: the flu. A virus with this type of cycle makes you sick right away. What about the other type of life cycle?. The . Lysogenic. Cycle. The . lysogenic. cycle is slower and more complex. Why is regulation of the cycle important?. 40%. Approximately 39.6 percent of men and women will be diagnosed with cancer at some point during their lifetime. . (based on 2010-2012 data).

Concept 9.3: The eukaryotic cell cycle is regulated by a molecular control system.

How many phases are in the cell cycle as shown in the diagram in Model 1?. Four.. 2. Starting at the starred cell, what is the order of the stages of a cell’s life?. G1, S, G2, M.. 3. During which phase does the size of the cell increase?. 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. Acknowledgement. I would like to express special thank of gratitude to our respected principal madam, Mrs. . Kuljit. . Kaur. , for giving us this unique opportunity to express ourselves in a creative way. 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, .
