Cell Transport Vocabulary

the substance that gets dissolved in a liquid to make a solution, like sugar in water

• positive feedback loop
• selective permeable
• homeostais

the process by which living things keep their internal environment stable and balanced, even when the outside environment changes

• positive feedback loop
• selective permeable
• homeostais
• solute

NGSS.HS-LS1-3

a process in which a change in the body causes an even bigger change in the same direction. For example, during childbirth, the hormone oxytocin causes contractions, and those contractions lead to more oxytocin being released.

• selective permeable
• homeostais
• solute

a membrane allows some substances to pass through it but blocks others, like a gatekeeper controlling what enters or leaves a cell.

• selective permeable
• homeostais
• solute

NGSS.MS-LS1-2

how much of a substance is in a certain amount of space, like the amount of salt in a glass of water.

• passive transport
• negative feedback loop
• concentration
• simple diffusion

when molecules move from an area of high concentration to an area of low concentration, like how perfume spreads through a room

• negative feedback loop
• passive transport
• concentration
• simple diffusion

the movement of substances across a cell membrane without using energy, like oxygen diffusing into a cell.

• negative feedback loop
• passive transport
• concentration
• simple diffusion

a process that helps the body maintain balance by reversing a change. For example, if your body gets too hot, it sweats to cool down and return to a normal temperature.

• concentration
• negative feedback loop
• simple diffusion

the movement of substances across a cell membrane using energy, often from low concentration to high concentration, like a pump pushing water uphill.

• isotonic solutions
• osmosis
• solvent
• active transport

solutions that have the same concentration of solutes as the inside of a cell, so there is no net movement of water in or out of the cell

• isotonic solutions
• osmosis
• solvent
• active transport
