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

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

Parts of a Cell

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.

Parts of a Cell

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

Parts of a Cell

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
