Passive Transport Flashcard

Front

What process allows water to move from a high concentration in soil to a low concentration in plant roots?

Back

Osmosis

Front

What is passive transport?

Back

The movement of ions from high to low concentration without requiring energy.

Front

What is osmosis?

Back

The net flow of water down the concentration gradient from high to low concentration.

Front

In which type of solution do red blood cells remain unchanged?

Back

Isotonic.

Front

What is a key difference between channel proteins and carrier proteins?

Back

Channel proteins transport molecules without contact, carrier proteins attach to molecules.

Front

Define diffusion.

Back

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

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution.

Front

What happens to a cell in a hypertonic solution?

Back

The cell shrinks as water moves out of it.

Front

What role do carrier proteins play in passive transport?

Back

They facilitate the movement of specific molecules across the cell membrane.

Front

Explain the term 'concentration gradient.'

Back

The difference in concentration of a substance across a space.
