1. Ms. Powell Animal and Plant Cells

2.  Greet the Teacher  Aisles should be clear  Take out Science Notebook  Begin Work on Board Silently! DAILY CLASS ROUTINE

3. CELLS  Cells are the basic units of function in all living things.  Cells in animals and plants have unique forms that allow each to take part in processes that are necessary for the cell and or/living thing to survive.

4.  “Small organ”  Carry out tasks for cell  Brings in food supplies  Get rid of waste  Repair the cell WHAT IS AN ORGANELLE?

5. ANIMAL CELL ORGANELLES

6.  Function: Holds the cell together and lets substances in and out (Semi-permeable)  Outer Layer of cell CELL MEMBRANE “The Bouncer”

7.  Function: Holds organelles in place  Jellylike substance in the cell  Made mostly of water CYTOPLASM

8.  Function: DNA is stored or held  Directs cell’s activities  Nucleolus: dark spot in the middle of the nucleus that help make ribosomes NUCLEUS “The Brain or the Boss”

9.  Function: Energy formation  Breaks down food to make ATP  ATP: major fuel for all cell activities that require energy MITOCHONDRION “The Power House”

10.  Function: Makes protein  Can be on Endoplasmic Reticulum or free in cytoplasm RIBOSOMES “Builders/Workers”

11.  Function: Processing and packaging center  Packages macromolecules, like protein and lipids as they are made in the cell  To be packaged & stored  Used to send them out of the cell GOLGI APPARATUS “UPS”

12. ENDOPLASMIC RETICULUM “Roads” Function: A membrane system of canals and tunnels that transport materials Rough ER: covered with ribosomes Smooth ER: pathway for molecules to move throughout the cell

13.  Functions:  1. breaks down food  2. destroys old or worn out cell parts  3. Engulfs viruses or bacteria LYSOSOME “Garbage Can”

14. So, what’s different about plant and animal cells? PLANT CELL ORGANELLES

15.  Function: Gives the cell a rigid shape (Structure and Support)  Outer layer of plant cells CELL WALL “Protector”

16.  Contain chlorophyll, a green chemical needed for photosynthesis.  Turns energy from the sun into nutrients (food) CHLOROPLASTS

17.  Function: Stores waste, water, and food  Plant cell Vacuoles are bigger than those in animal cells! Vacuole “Storage Tank”

18. USING NOTES FILL OUT FOR ANIMAL & PLANT CELL
