Can you identify these cells?
Can you remember the function of these organelles?
• Nucleus
– Control center
• Ribosome
– Make proteins
• Cell wall
– Supports & Protects the cell
• Golgi body
– Packages proteins and other
molecules (FedEx)
• Chloroplast
– Contain chlorophyll
– Assist in photosynthesis
• Cell membrane
– Selectively permeable
– Control what enters & exits
cells
• Mitochondria
– Power house
• Vacuole
– Stores materials such as food,
water or waste.
How do things get in & out of a cell?
• Passive Transport
– Diffusion
– Osmosis
- Moves from high to low
concentration
Active Transport
- Needs cell energy
