1. DO NOW Describe the process in which proteins and lipids are transported out of the cell (Name and describe the function of all organelles involved in this process) Why is the nucleus known as the “control center?” Homework: Review packet due tomorrow! Money ($15) for review book due Thursday. Quiz Thursday!

2. Vacuoles Storage bins to the cells Found in both animal and plant cells, but larger in plant cells Store waste products so the rest of the cell is protected from contamination Structure: membrane that surrounds a mass of fluid

4. The Parts of The Eukaryotic Cell Vacuoles A sac of fluid surrounded by a membrane used to store food, fluid, or waste products.

5. Lysosomes  Function: digest food, breakdown old cell parts and foreign invaders  Contains hydrolytic enzymes (digestive enzymes)  Originates from the Golgi apparatus Video

7. Here's something scientists are still trying to figure out. If the lysosome holds many types of enzymes, how can the lysosome survive? Lysosomes are designed to break down complex molecules and pieces of the cell. Why don't the enzymes break down the membrane that surrounds the lysosome?

8. The Parts of The Eukaryotic Cell B) Lysosomes Contain a digestive enzyme. Can fuse with vacuoles to digest food, or can digest worn cell parts. Also known as “suicide sacs” because they can also destroy the whole cell.

9. Mitochondria  Digestive system: Takes in nutrients, breaks them down, and creates energy rich molecules for the cell  Site for cellular respiration  Contains two membranes (double-membrane organelle)

10.  Lets draw the mitochondria

11. Video

12. The Parts of The Eukaryotic Cell 6) Energy Transformers A) Mitochondria Produce the energy for the cell. Also known as the “powerhouse of the cell”. Has a highly folded inner membrane (cristae).

13. Chloroplasts  Food producers of the cell  Animal cells DO NOT have chloroplasts  Function: to convert light energy of the sun into sugars used by cells  CHLOROPHYLL molecules in the chloroplast capture light energy from the sun

14.  Lets draw the chloroplast Photosynthesis

15. The Parts of The Eukaryotic Cell B) Chloroplasts -- Found in plant cells and some protists. -- Transforms light energy into chemical energy which is stored in food molecules. -- Contain chlorophyll – a green pigment that traps light energy and gives plants their green color.
