Transcript of "Cell reproduction part 2"

  1. 1. Notes: Life of a CellPart 2: Cell Reproduction
  2. 2. Cell Reproduction• According to the CELL THEORY, all CELLS come from PREEXISTING cells and have the capability of reproducing• Life is based on the reproduction of cells or “CELL DIVISION”
  3. 3. I. What is Cell Division?• PRODUCTION of DAUGHTER cells
  4. 4. II. What will happen because of celldivision?• GROWTH and DEVELOPMENT: because of an increase in cell number, cell size, and cell products, the organism grows in stages and shows developmental difference.
  5. 5. III. Two Types of Cell Division Asexual SexualSet up a table Or tree map in space provided
  6. 6. Asexual• Mother cell reproduces 2 IDENTICAL daughter cells• Example: MITOSIS• Types of cells reproduced: body cells (somatic)• Happens in both Eukaryotic and Prokaryotic cells
  7. 7. Sexual• After sperm and egg are produced, fusion of these cells produces a non-identical cell• Example: Meiosis• Types of cells produced: sperm/egg• Only in Eukaryotic cells
  8. 8. IV. Eukaryotic Cell Division – Up CloseA. The CELL CYCLE: events of the cell that happen before, during, and after cell divisiono THREE special events: Interphase (I), Mitosis (M), and Cytokinesis (C)
  9. 9. 1. Interphase (I): 70-90% of cell’s life• NO active cell division• 3 phases: G1, S, G2
  10. 10. Make an Interphase flow map on the bottom of your paper:Interphase G1 S Phase G2 • 3 • Growth • DNA • Final Phases • Metabolic copies growth processes
  11. 11. 2. Mitosis (PMAT): DIVISION of the cell’sNUCLEUS • Separation of CHROMOSOMES in a series of processes • Resulting cell has 2 new NUCLEI • 4 distinct phases: PMAT
  12. 12. 3. Cytokinesis (C): final DIVISION of theCell’s CYTOPLASM • 2 new DAUGHTER cells (Identical) • Animal cells pinch or cleave into 2 cells • Plant cells separate as new cell wall divides the 2 cells
