Cell Transport

Front

What is osmosis?

Back

Osmosis is the process by which water molecules move across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration, helping to maintain cellular balance.

Front

What is phagocytosis?

Back

Phagocytosis is a type of endocytosis where a cell engulfs large particles or other cells, often referred to as 'cell eating'.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, relying on the kinetic energy of the molecules.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, a cell can swell and burst due to the influx of water.

Front

What is the direction of water movement when a red blood cell is placed in distilled water?

Back

Water molecules will move into the red blood cell.

Front

What is active transport?

Back

Active transport is the process of moving substances against their concentration gradient, requiring energy (usually in the form of ATP).

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is the role of carrier proteins in cell transport?

Back

Carrier proteins facilitate the transport of specific substances across a cell membrane by changing shape.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials in vesicles that fuse with the plasma membrane.

Front

What is pinocytosis?

Back

Pinocytosis is a type of endocytosis where a cell engulfs small particles or liquids, often referred to as 'cell drinking'.
