1. Parts of a cell Chapter 1

2. Table of Contents  Add the following under Science Process Skills to your table of contents:  Parts of a cell-----------------pg you start on ***Then turn to that page….it MUST be a clean page! Label that page PARTS OF A CELL at the top~~

3. Vocabulary  Cut the vocabulary words and definitions out of your workbook on page 2 and paste into your Science Journal

4. Cell Theory  Cut out Cell Theory graphic organizer on page 3 of your workbook and paste below the vocabulary words.

5. Parts of a cell:  Paste in the parts of a cell handout

6. Parts of the cell  Nucleus- Directs what happens in a cell. Holds DNA (chromosomes)  Cell Membrane- Thin cover wrapped around all cells. Lets in food, water and gases. Lets wastes leave  Cytoplasm- Jelly like substance between the nucleus and cell membrane. All other organelles float in this

7. Parts of a Cell

8. Parts of a cell  Mitochondria- large and peanut shaped. “power plant” of the cell. Creates energy for the cell  Vacuoles- sacs filled with liquid. They hold water, food and wastes. Animal cells- many small vacuoles Plant cells- one large  Ribosomes- make proteins which help chemical reactions occur. Very Tiny.

10. Parts of a cell  Golgi apparatus- takes in proteins and changes them so they are ready to leave the cell  Endoplasmic Reticulum(ER)- Group of membranes and tubes that form tunnels. This is how material moves through the cell. 2 types- rough and smooth  Cell Wall- Only in plant cells. Stiff outer layer around the cell membrane. Gives support and protection

12. Parts of a cell  Chloroplasts- only in plant cells. Use energy from sunlight to make food.  Lysosomes- small and round. Help break down food and old cell parts Can be found in SOME plant cells Mostly found in animal cells
