Presentation Transcript

  1. Cell Organelles and Their Functions

  2. The Animal Cell

  3. The Plant Cell

  4. The Cell Membrane • Function- controls the movement of materials into and out of the cell

  5. The cytoplasm • Cytoplasm fills cell from the nucleus to the cell membrane; includes fluid, cytoskeleton, and all organelles (except nucleus)

  6. The endoplasmic reticulum • A pathway for the transport of materials throughout the cell; rough and smooth

  7. The nucleus • Holds genetic material; controls cell functions

  8. Nucleolus • Round body within the nucleus; where ribosomes are made.

  9. Ribosomes • They build protein; made of RNA and protein. Some are free, some attached to ER.

  10. Lysosomes • Contain digestive enzymes that break down large molecules, old cells, worn-out organelles

  11. Mitochondria • The powerhouse of the cell; transfers energy from organic molecules to ATP

  12. Golgi Apparatus • Packages and secretes products of the cell.

  13. Centrioles (animal cells) • Involved in cell division in animal cells

  14. Vacuoles • Store food, waste, and water and dissolved materials. Animal cell vacuoles form and reform over and over again.

  15. Cell Wall • Gives a plant cell its shape; provides structure; not found in animal cells

  16. Cilia • Short hairlike structures that enable a single-celled organism to move; also line respiratory tract

  17. Flagella • Long, hairlike structures used for movement

  18. Chloroplast • Contains chlorophyll to capture light for photosynthesis; site of photosynthesis

  19. Chromosomes • Rod-shaped bodies found in the nucleus; composed of DNA

  20. Microtubule • Cylinders that support and give the cell shape

  21. Pink fuzzy slippers • What organelle do these represent?
