Cell Transport MOD

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, leading to water moving out of cells.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, causing water to move into cells.

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes compared to another solution, resulting in no net movement of water.

Front

What is osmosis?

Back

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

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in substances by engulfing them in a membrane.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles that fuse with the cell membrane.

Front

What role do cell membranes play in transport?

Back

Cell membranes regulate the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance across a space, influencing the direction of diffusion.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.
