Presentation Transcript

  1. The Parts of the Cell

  2. Cytoplasm- fluid filled interior of cell- suspends cell organelles

  3. Cytoskeleton - internal support system for cell - made of microfilaments and microtubules - assists in movement of organelles within the cell

  4. The Nucleus 

  5. Nucleus • Surrounded by a nuclear envelope with nuclear pores • Contains the genetic information (DNA) which exists as chromatin in a non-dividing cell • Controls all cell activities • Nucleolus • In the center of the nucleus • Produces the ribosomes

  6. Mitochondria - Produces cellular energy in the form of ATP through a process called cellular respiration (metabolizes glucose)

  7. Figure 4.17

  8. Ribosomes -site of protein synthesis -links amino acids together to form proteins

  9. EndoplasmicReticulum- transport system within the cell- transport cell materials- two types: rough (with ribosomes) and smooth

  10. Rough ER -has ribosomes which give it its "rough" appearance-functions in protein synthesis Smooth ER -mostly contains enzymes that function in lipid synthesis)

  11. Figure 4.10a

  12. GolgiApparatus --flattened stacks of membranes --collects, packages and modifies cell materials to be used in other parts of the cell or transported out of the cell

  13. Lysosomes -digests and recycles old cell parts, sometimes bacteria -contain high levels of enzymes

  14. Vacuole • mainly storage of water in plant cells, some waste - some animal cells have small vacuoles

  15. Chloroplasts --only found in plant cells --organelle where photosynthesis occurs --functions to convert light energy to glucose

  16. Centrioles - used during cell division to move and separate chromosomes • only found in animal cells

  17. Flagella • whip-like structure • function in movement Cilia • numerous little hairs • function in movement

  18. Pseudopod – cytoplasmic extensions that help some cells to move and feed, as in amoebas
