 In pure water, a red blood cell from an animal will swell and burst, but a leaf cell from a plant will not. Which structure in the leaf cell is responsible for this difference?

• cell membrane
• cell wall
•  mitochondrion
• nucleus

The diffusion of water across a selectively permeable membrane is called 

• active transport
• facilitated diffusion
• osmosis
• phagocytosis

During diffusion molecules tend to move 

•    up the concentration gradient
•  from an area of lower concentration to an area of higher concentration
•  in a direction that doesn’t depend on concentration
•  down the concentration gradient

The amount of particles in a given space.

• diffusion
• concentration
• permeable
• active transport

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

Particles are removed from a cell (pushed out).

• Endocytosis
• Exocytosis
• Permeable
• In high concentration
