TOPIC: Cells AIM: Describe the different cell organelles and their functions. Do Now: Explain what organisms consist of. HW: Read p. 39. Write a paragraph describing the two types of cells that exist.
Plasma Membrane • Surrounds the cell
Semi-permeable or Selectively permeable: controls what enters & leaves the cell
Cytoplasm is the gelatin-like material that is found inside the cell membrane.
Jellylike material • Holds cell organelles
“BRAIN” of the cell (Control center of the cell)
Controls all cell activities • Stores hereditary information (DNA)
Found • Floating free in cytoplasm
Channels in the cytoplasm • Used to TRANSPORT materials • 2 types of ER:
TOPIC: Cells AIM: Describe the different cell organelles and their functions. Do Now: Take out your notes packet. You will be using the space under the Endoplasmic reticulum box. Write out numbers 1 – 10. HW: Work on your science fair project!
Identify the cell organelle described: • Controls all cell activities. • Produces proteins. • Is selectively permeable. • Transports substances around the cell.
6. Produces ribosomes. 7. Has ribosomes on its surface. 8. Holds all cell organelles. 9. Contains DNA. 10. Controls what enters and leaves the cell.
“POWERHOUSE” of the cell Mighty Mitochondria
Animal = many small • Plant = few large
“UPS / POST OFFICE” • Collects, packages, and sends materials out of the cell
Contain digestive enzymesthat: 1. digest food 2. break down old organelles & bacteria
