Cell Transport

The movement of molecules from an area of high concentration to an area of low concentration.

• Osmosis
• Respiration
• Diffusion
• Active Transport

Cells use energy to move materials across a membrane (low to high concentration).

• Active transport
• Passive transport
• Diffusion
• Osmosis

Cells transport material across a cell membrane without using energy (high to low concentration)

• Passive transport
• Concentration
• Endocytosis
• Active Transport

Cell membrane surrounds a particle and encloses it (for large particles)

• Endocytosis
• Exocytosis
• Permeable
• In high concentration

Particles are removed from a cell (pushed out).

• Endocytosis
• Exocytosis
• Permeable
• In high concentration

Why are diffusion and osmosis important to cells?

• It allows them to take in materials/substances 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?

• Allow certain things to enter and leave the cell

• Nothing gets through

• The cell lets only large substances through
