Presentation transcript:

Cell Structure

Cell Organelles Little organs- carry out life processes in the cell

1. Lysosome Cellular digestion, contains enzymes

2. Golgi Apparatus Collects, packages, modifies molecules

3. Mitochondria “Powerhouse”, releases energy (ATP)

4. Centrioles ANIMAL cell reproduction

5. Vacuoles- Storage

6. Ribosomes- Site of protein synthesis

7. E. Reticulum Intracellular transport (within the cell)

8. Nuclear Envelope Separates nucleus from cytoplasm –Cytoplasm- living material between nucleus and cell membrane

9. Nucleolus Small body in nucleus (RNA & protein)

10. Nucleus Control center of the cell

11. Chromosomes Contain the genetic material (DNA)

12. Chloroplast PLANT cells, contains chlorophyll

13. Cell Wall PLANT cells only, protect & support

14. Cell Membrane “Gatekeeper”, controls what enters & leaves the cell

Cell Theory Explains the basic role of cells in living things

3 parts 1. All living things are made of cells

3 parts 2. Cells are the basic unit of structure and function in living things –structure- what it is made of –function- what it does

3 parts 3. All cells come from pre-existing cells

5 Individuals & Contributions

Van Leeuwenhoek Developed microscope 1 st to describe living cells

Hooke 1st to observe cells, dead cork cells

Schleiden All plants are composed of cells

Schwann All animals are composed of cells

Virchow All cells come from other cells
