  3. 3. Cell growth <ul><li>Limits to cell growth </li></ul><ul><li>Division of the cell </li></ul>Back Cell growth - Cell growth and division
  4. 4. Cell division <ul><li>Chromosomes </li></ul><ul><li>Cell cycle </li></ul><ul><li>Mitosis </li></ul><ul><li>Cytokinesis </li></ul>Back Cell division - Cell growth and division
  5. 5. Regulating the Cell Cycle <ul><li>Controls on cell division </li></ul><ul><li>Cell Cycle regulators </li></ul><ul><li>Uncontrolled cell growth </li></ul>Back Regulating the cell cycle - Cell growth and division
  6. 6. Limits to cell growth <ul><li>DNA overload </li></ul><ul><li>Exchanging materials </li></ul><ul><li>Ratio of surface area to volume </li></ul>Back Limits to cell growth - Cell growth and division
  7. 7. DNA overload <ul><li>When a cell is small, its DNA is able to meet all of the cell’s needs. </li></ul><ul><li>As the cell grows it produces more organelles, but the DNA is not replicated and it cannot meet the cell’s needs. </li></ul>Back DNA overload - Limits to cell growth
  8. 8. Exchanging materials <ul><li>The rate at which food and oxygen are used up and waste products are produced depends on the cell’s volume. </li></ul><ul><li>As the cell grows it becomes more difficult for it to get rid of wastes and to get food and oxygen into the cell. </li></ul>Back Exchanging materials - Limits to cell growth
  9. 9. Ratio of surface area to volume <ul><li>Imagine a cell that is shaped like a cube. </li></ul><ul><li>The surface area of a cell would be equal to length x width x number of sides(6) of a cell. </li></ul><ul><li>The volume of the cell would be equal to length x width x height of the cell. </li></ul><ul><li>The volume of the cell increases more rapidly than the surface area. </li></ul>Back Example Ratio of surface area to volume - Limits to cell growth
  10. 10. Example Cell size Surface area volume Ratio of surface area to volume Back Ratio of surface area to volume - Limits to cell growth
  11. 11. Division of the cell <ul><li>The process by which a cell divides into two new daughter cells is called cell division. </li></ul><ul><li>Before the cell divides, it replicates all of its DNA. </li></ul><ul><li>This process reduces cell volume and solves the DNA overload problem. </li></ul>Back Division of the cell – Cell growth
  12. 12. Chromosomes <ul><li>The information that is passed from one generation to the next is carried by chromosomes. </li></ul><ul><li>They are made up of DNA and proteins </li></ul><ul><li>A chromosome consists of two sister chromatids. </li></ul>Back Chromosomes – Cell division
  13. 13. Cell cycle <ul><li>The cell cycle is divided into four phases, which are: </li></ul><ul><ul><li>G1 phase: the cell grows </li></ul></ul><ul><ul><li>S phase: DNA is replicated </li></ul></ul><ul><ul><li>G2 phase: The cell prepares to divide </li></ul></ul><ul><ul><li>M phase: mitosis and cytokinesis </li></ul></ul><ul><li>The G1, S and G2 phases are part of the interphase in the cell cycle. </li></ul>Back Cell cycle – Cell division
  14. 14. Mitosis Back Prophase Metaphase Anaphase <ul><li>Telophase </li></ul>Cytokinesis Cell Cycle Mitosis – Cell division
  15. 15. Prophase <ul><li>During prophase, the chromosomes become visible. The centrioles take positions in opposite sides of the cell and form the spindle. </li></ul>Back Next Prophase - Mitosis
  16. 16. Metaphase <ul><li>During metaphase, the chromosomes line up across the center of the cell. </li></ul><ul><li>Microtubules connect the centromere of each chromosome to the two poles of the spindle. </li></ul>Back Next Return Metaphase - Mitosis
  17. 17. Anaphase <ul><li>During Anaphase, the centromeres that joined the sister chromatids split becoming individual chromosomes. </li></ul>Back Next Return Anaphase - Mitosis
  18. 18. Telophase <ul><li>The chromosomes move to opposite sides of the cell and a nuclear envelope forms around each group of chromosomes. </li></ul>Back Return Telophase - Mitosis
  19. 19. Cytokinesis <ul><li>The process in which the cytoplasm separates, forming completely the two new daughter cells. </li></ul><ul><li>It usually occurs about the same time as Telophase. </li></ul><ul><li>This occurs different in plants and in animals. </li></ul>Back Cytokinesis – Cell division
  20. 20. Animals <ul><li>The cell membrane is drawn inwards until the cytoplasm is pinched into two nearly equal parts. </li></ul><ul><li>Each part contains its own nucleus and cytoplasmic organelles. </li></ul>Back Animals - Cytokinesis
  21. 21. Plants <ul><li>A structure known as the cell plate forms midway between the divided nuclei. </li></ul><ul><li>The cell plate gradually develops into a separating membrane. </li></ul><ul><li>A cell wall then begins to appear in the cell plate. </li></ul>Back Plants - Cytokinesis
  22. 22. Controls on cell division <ul><li>Cells have a characteristic that allows them to know when to stop growing and dividing. </li></ul><ul><li>When cells come into contact with other cells, they respond by not growing. </li></ul>Back Controls on cell division – Regulating the cell cycle
  23. 23. Cell cycle regulators <ul><li>The cyclin is a protein that regulates the cell cycle in eukaryotic cells. </li></ul><ul><li>There are two types of regulating proteins: </li></ul><ul><ul><li>Internal Regulators </li></ul></ul><ul><ul><li>External regulators </li></ul></ul>Back Cell cycle regulators – Regulating the cell cycle
  24. 24. Internal regulators <ul><li>Allow the cell cycle to proceed only when certain processes have happened inside the cell. </li></ul><ul><li>It prevents a cell from entering anaphase until all its chromosomes are attached to the spindle. </li></ul>Back Internal regulators – Cell cycle regulators
  25. 25. External regulators <ul><li>They are proteins that respond to events outside the cell </li></ul><ul><li>They direct cells to speed up or slow down the cell cycle </li></ul><ul><li>They prevent excessive cell growth </li></ul>Back External Regulators – Cell cycle regulators
  26. 26. Uncontrolled cell growth <ul><li>The consequences of uncontrolled cell growth in a multicellular organism are very severe. </li></ul><ul><li>An example could be cancer, which is a disorder in which some of the body’s own cells lose the ability to control growth </li></ul><ul><li>Cancer cells do not respond to the signals that regulate the growth of most cells. </li></ul>Back Uncontrolled cell growth – Regulating the cell cycle
