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

Osmosis is a form of ______________. 

• Passive Transport
• Active Transport

Solutes move with the concentration gradient, therefore no energy is used. 

• Passive Transport
• Active Transport

Low to high concentration.

• Passive Transport
• Active Transport

Uses ATP (energy)

• Passive Transport
• Active Transport

What process occurs when WATER diffuses across a membrane?

• endocytosis
• facilitated diffusion

• osmosis
• exocytosis

Why is diffusion and osmosis important to cells?

• It allows them to take in materials without using energy.
• It allows them to reproduce.
• It allows them to absorb sunlight.
• It allows cells to use all energy.

What does selectively-permeable mean?

• The cell controls what passes in and out of the cell
• Nothing gets through the cell membrane

• The cell lets only large substances through
• The cell lets everything through the cell membrane

What is diffusion?

• when molecules move from low to high concentration

• when molecules move from a high to low concentration

• no movement of molecules through the membrane

• molecules move everywhere throughout the cell
