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?”

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
The Parts of The Eukaryotic CellVacuoles
A sac of fluid surrounded by a membrane used to store food, fluid, or waste products.
Lysosomes
Function: digest food, breakdown old cell parts and foreign invaders
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?
The Parts of The Eukaryotic CellB) 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.
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)
