Biology: Cell Transport

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport

Solutes move against the concentration gradient, therefore energy is needed. 

• Passive Transport
• Active Transport

Uses ATP (energy)

• Passive Transport
• Active Transport

• Active Transport
• Facilitated Diffusion

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole
• nucleus
• cell membrane
• cell wall

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport

What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 
• Movements of substances through a membrane. 
• When molecules spread from High to Low concentration on their own. 
• When pressure pushes something through a membrane.
