What is endocytosis?

Back

Endocytosis is a type of cell transport where cells engulf substances from the outside environment, bringing them into the cell.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What happens to a cell in a low/no solute solution?

Back

A cell in a low/no solute solution will swell as water moves into the cell.

Front

What is dynamic equilibrium in cellular transport?

Back

Dynamic equilibrium is the state when material passes into and out of a cell at equal rates, resulting in no net change in concentration inside and outside the cell.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any type of molecules.

Front

What occurs when a cell is placed in distilled water?

Back

When a cell is placed in distilled water, it will swell due to the influx of water.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to shrink.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to swell.
