Cell Transport Study Set

A cell structure that controls which substances can enter or leave the cell.

• cell membrane
• selectively permeable
• active transport
• passive transport

a property of cell membranes that allows some substances to pass through, while others cannot

• selectively permeable
• active transport
• passive transport
• Concentration

the movement of materials through a cell membrane using energy

• active transport
• passive transport
• Concentration
• Diffusion

The movement of materials through a cell membrane without using energy

• passive transport
• Concentration
• Diffusion
• Osmosis

the amount of a particular substance in a given quantity of a mixture; substances move from high to low

• Concentration
• Diffusion
• Osmosis
• Facilitated diffusion

Natural movement of molecules from an area of higher concentration to an area of lower concentration.

• Diffusion
• Osmosis
• Facilitated diffusion
• Equilibrium

Diffusion of water through a selectively permeable membrane

• Osmosis
• Facilitated diffusion
• Equilibrium
• Endocytosis

Movement of specific molecules across cell membranes through protein channels

• Facilitated diffusion
• Equilibrium
• Endocytosis
• Exocytosis

state in which particles are evenly distributed and there is zero net movement

• Equilibrium
• Endocytosis
• Exocytosis
• Homeostasis

type of active transport where the cell membrane takes in particles by changing shape and engulfing the particle

• Endocytosis
• Exocytosis
• Homeostasis
• Amoeba
