Nucleus

Cell control center with DNA.

Mitochondria

Makes energy for the cell.

Chloroplast

Does photosynthesis.

Makes proteins.

Rough ER

Protein-making transport system.

Smooth ER

Golgi

Packages and ships materials.

Lysosome

Breaks down waste.

Vacuole

Storage space in the cell.

Cytoplasm

Jelly-like inside of the cell.

Membrane

Controls entry/exit of materials.

Active Transport

Transport using energy.

Passive Transport

Transport needing no energy.

Diffusion

Molecules spread out.

Facilitated Diffusion

Helped diffusion with proteins.

Hypertonic

Cell shrinks as water leaves.

Hypotonic

Cell swells as water enters.

Endocytosis

Cell takes in stuff.

Phagocytosis

Cell 'eats' big solids.

Exocytosis
