  1. Energy Transformations

  2. Adenosine Triphosphate • Adenine • Ribose • 3 Phosphates

  3. Plant cell—photosynthesis

  4. Chloroplast

  5. photosynthesis

  6. Energy transformation for photosynthesis • Light energy to chemical energy

  7. Animal cell—respiration (all cells too)

  8. Mitochondria

  9. Cellular respiration

  10. Energy Transformation for Cellular Respiration • Chemical energy to chemical energy

  11. Respiration and PhotosynthesisakaOxygen/Carbon Dioxide Cycle

  12. Cell Reproduction Cell Cycle Mitosis & Meiosis

  13. Cell cycle • Interphase • G1 • S • G2 • Mitosis • Prophase • Metaphase • Anaphase • Telophase • Cytokinesis

  14. Interphase • Period of growth, normal cell functioning

  15. Mitosis • Makes two cells that are genetically identical • Makes body/somatic cells • Are diploid

  16. Prophase • Chromatin coils up into visible chromosomes • Nuclear membrane disappears • Spindle fibers appear. • Metaphase • Chromosomes line up in the middle of the cell. • Anaphase • Spindle fibers pull the chromosomes apart , attached at the centromeres. • Telophase • Chromosomes uncoil back in to chromatin • Spindle disappears • Nuclear membranes re-appear around each set of chromosomes.

  17. Meiosis • Results in 4 cells that are genetically different from each other • Makes sperm & eggs • Are haploid

  18. Prophase I • Chromatin coils up into visible chromosomes • Nuclear membrane disappears • Spindle fibers appear. • Chromosomes pair up in 2 homologous pairs called tetrads • Crossing over occurs.

  19. Metaphase I • Tetrads line up in the middle of the cell. • Anaphase I • Tetrads are separated from each other into homologous pairs • Telophase I • Two nuclear membranes formed • Prophase II, Metaphase II, Anaphase II • Same processes repeat in both cells. This time, the homologues are split into separate chromosomes. • Telophase II • Chromosomes uncoil back in to chromatin • Spindle disappears • Nuclear membranes re-appear around each set of chromosomes. • Four new cells are formed!
