diffusion To Study

Chloroplast

An organelle found in plant cells where photosynthesis occurs.

Mitochondria

Cellular structures where cellular respiration occurs in living organisms.

Photosynthesis

The process by which plants use sunlight to synthesize foods with the help of carbon dioxide and water.

Cellular Respiration

The process in which cells convert glucose and oxygen into energy, carbon dioxide, and water.

ATP

Adenosine triphosphate, the energy currency of the cell.

Diffusion

The net movement of molecules from an area of higher concentration to an area of lower concentration.

Equilibrium

A state in which the molecules of a substance are evenly distributed throughout a space.

Selective Permeability

A property of cellular membranes that allows certain molecules to pass through while blocking others.

Osmosis

The diffusion of water through a selectively permeable membrane.

Hypotonic Solution

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

Isotonic Solution

A solution with the same concentration of solutes as another solution.

Hypertonic Solution

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

Active Transport

The movement of molecules across a cell membrane requiring energy input.

Passive Transport

The movement of molecules across a cell membrane without the use of energy.

Endocytosis

A process by which cells take in materials that are too large to pass through the cell membrane.

Exocytosis

The process by which a cell expels materials in bulk.
