Presentation Transcript

  1. Cells • Cells are the most important things in the world!

  2. Cells are organized to divide labor and make them more efficient.

  3. Cell membrane • Phospholipid bilayer • Transport proteins help move materials in and out of the cell • Carbohydrate chains help mark the cell • Cholesterol stabilizes membrane

  4. It is a membrane-bound organelle and is surrounded by a double membrane. • It communicates with the surrounding cytosol via numerous nuclear pores. Nucleus

  5. Within the nucleus is the DNA responsible for providing the cell with its unique characteristics.

  6. Nucleolus Produces ribosomes. Not membrane bound. Made of DNA and protein.

  7. Nuclear Envelope • Double plasma membrane • Pores • Regulates what goes in and out of the nucleus

  8. Chromosomes and Chromatin • Made of DNA and protein • Contain genetic instructions • These chromosomes are wound up DNA and protein

  9. Endoplasmic Reticulum • E.R. is made of plasma membranes and has two forms • Smooth that has no ribosomes • Packages, modifies and transports lipids • Detoxifies alcohol • Rough that has ribosomes attached • Transports, packages and modifies protein • Where most protein synthesis occurs

  10. Golgi Apparatus • Is made of membrane • Packages materials for export from the cell • Seen here in lower middle of cell with vessicles budding off.

  11. Mitochondria • Has a double unit membrane • Has its own DNA • Converts the energy from glucose into ATP

  12. Fluid of the cell Where cell reactions take place Allows chemicals to mix and diffuse Cytoplasm/Cytosol

  13. Surrounded by plasma membrane Storage containers for Pigment Water Food waste Vacuoles

  14. Has a plasma membrane Contain digestive enzymes so the cell can: Get rid of worn out cell parts Get rid of invading cells and poisons Self destruct Lysosomes animation

  15. Made of microtubules and microfilaments Gives the cell organelles support Helps with internal transportation of materials Cytoskeleton

  16. Ribosome • Assembles proteins from amino acids

  17. Centriole • Helps cell divide

  18. Cell Wall • Found on plant cells, fungus cells and bacteria cells • Made of complex carbohydrates • Gives the plant cell shape and support • Prevents bursting from osmotic pressure

  19. Double plasma membrane and its own DNA Converts light into glucose by the process of photosynthesis Chloroplast
