Cell Membrane and Transport Review

When the concentration of particles inside of a cell is the same as the concentration of particles outside of the cell. 

• active transport
• concentration
• diffusion
• equilibrium

The process where only water is allowed to pass through the cell membrane from a high to low concentration.

• meiosis
• respiration
• diffusion
• osmosis

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

Which of the following is an example of osmosis?

• Oxygen exiting leaves after photosynthesis
• A raisin swelling in a cup of water
• Water changing from a liquid to a gas
• Oxygen moving into an animal cell

Why are 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 lets only large substances through
