  1. Going Cellular

  2. Organisms can be unicellular . . .

  3. or Muticellular

  4. How many cells are in the human body? Over 100 trillion cell or Over 100,000,000,000,000 cells

  5. Cell Vocabulary • Cell Membrane • Cytoplasm • Nucleus • Endoplasmic Reticulum • Ribosomes • Golgi Apparatus • Mitochondria • Chloroplasts • Cell Wall

  6. Name: Cell Membrane Function: Boundary between the cell and its environment. The membrane determines what goes into the cell and what moves out.

  7. Name: Cytoplasm Function: Jelly-like fluid in cell that hold organelles in place.

  8. Name: Nucleus Function: Stores DNA. The DNA controls the functions of the cell.

  9. Name: Endoplasmic Reticulum Function: Rough ER has ribosomes to make proteins. Smooth ER makes and stores lipids.

  10. Name: Ribosomes Function: Place where proteins are synthesized or made.

  11. Name: Golgi Complex or Golgi Apparatus Function: Sorts and packages proteins to be shipped off.

  12. Name: Mitochondria Function: Takes food and turns it into energy for the cell. This is called cell respiration.

  13. Name: Chloroplast (PLANTS ONLY) Function: Uses light energy to make food for plants. This is called photosynthesis.

  14. Name: Cell Wall (PLANTS ONLY) Function: Structure outside of the cell membrane that provides support and protection.

  15. Lysosomes

  16. What cell parts would be involved in synthesizing proteins? Ribosomes Rough ER Nucleus

  17. Vesicles

  18. Vacuoles PLANT CELLS HAVE LARGE, CENTRAL VACUOLES ANIMAL CELLS HAVE VERY SMALL VACUOLES

  19. Homework: You need to copy down your homework assignment. Using your notes and your book, you are going to explain how proteins are made in one paragraph in YOUR OWN WORDS. Use the words: DNA, nucleus, endoplasmic reticulum, ribosome, protein, amino acids, Golgi apparatus, cell membrane.

  20. Example • The DNA holds the instructions in the nucleus. These instructions are passed to the ribosomes on the endoplasmic reticulum. The ribosomes put together amino acids to make a protein. Next the Golgi apparatus finishes and packages these finished products. Finally, the proteins are shipped out of the cell through the cell membrane.

  21. Now we are going to look at and label Animal Cell Plant Cell

  22. Microscope

  23. ClassworkWhat to do for each slide viewed • Write the name of the organism or part of the organism shown in the slide. • Draw a circle under the organism’s name. • Draw a picture of what you see in that slide in the circle. • Determine if it is a plant, an animal, or bacteria. Cardiac Muscle Cells

  24. Answer the following: • Did all of the cells look similar? • Which cell parts were the easiest to see? • Do the cells of bacteria look like the cells of plants and animals?
