Presentation Transcript

  1. The nucleus, like all cell organelles, are surrounded by a membrane to separate from other internal cellular structures and the cytoplasm.

  2. The nucleus, like all cell organelles, are surrounded by a membrane to separate from other internal cellular structures and the cytoplasm.

  3. The nucleus contains the cells genetic material, the chromosomes.

  4. Mitosis, or nuclear division, occurs when cells divide.

  5. The nucleus contains the nucleolus, which is NOT membrane bound.

  6. Ribosomes are made by the nucleolus within the nucleus. Therefore, the ribosomes must leave the nucleus before they can do their jobs within the cytoplasm as free floating ribosomes or while attached to endoplasmic reticulum as rough ER.

  7. Rough endoplasmic reticulum

  8. Protein synthesis is the responsibility of the ribosomes.

  9. Smooth endoplasmic reticulum Smooth endoplasmic reticulum is responsible for synthesizing fats (lipids) in the cell and detoxifying some harmful chemical such as alcohol

  10. Vesicles transport membrane bound packages of cell materials within the cell between other membrane bound cell structures like the ER , golgi apparatus and cell membrane. Specialized vesicles become lysosomes or peroxisomes.

  11. Membrane bound structures within the cell ‘communicate’ with each other by passing substances throughout the interconnected membranes.

  12. mitochondria

  13. Aerobic respiration occurs within the mitochondria. This process produces ATP (adenosine tri phosphate), the cell’s chemical energy.

  14. Cytoskeleton is made up of various protein structures that either give a cell shape/structure OR allow for transport of the cell or substances within the cell – for example chromosomes during mitosis.

  15. Flagella is an example of a cytoskeleton structure.

  16. Cilia are examples of cytoskeleton structures.

  17. The contractile proteins (actin and myosin) of your skeleton muscles are examples of cytoskeleton structures.

  18. Cytoskeleton structures also bind the cell membranes of adjacent cells.

  19. Vacuoles are membrane bound structures that store nutrients or waste within a cell.
