What is exocytosis?

Back

Exocytosis is the process by which cells expel materials by vesicles fusing with the cell membrane.

Front

What is cellular respiration?

Back

Cellular respiration is a series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP.

What is osmosis?

Back

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

Front

What is a hypotonic solution?

Back

A hypotonic solution is one where the concentration of solutes is lower outside the cell than inside, causing the cell to gain water and swell.

Front

What is a hypertonic solution?

Back

A hypertonic solution is one where the concentration of solutes is higher outside the cell than inside, causing the cell to lose water and shrink.

Front

What is active transport?

Back

Active transport is the movement of materials through a cell membrane using energy, often against a concentration gradient.

Front

What is passive transport?

Back

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

Front

What is phagocytosis?

Back

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

What is pinocytosis?

Back

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