Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration until equilibrium is reached.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high 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, using energy in the form of ATP.

Front

What is a buffer in biological systems?

Back

A buffer is a solution that resists changes in pH when small amounts of acid or base are added, helping to maintain a constant pH in biological systems.

Front

What are the two main reactants of cellular respiration?

Back

The two main reactants of cellular respiration are glucose (C6H12O6) and oxygen (O2).

Front

What is endocytosis?

Back

Endocytosis is the process by which cells engulf external substances, bringing them into the cell in a vesicle.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles, releasing them outside the cell.

Front

What is the role of biotechnology in agriculture?

Back

Biotechnology can improve agriculture by increasing crop yields, reducing pest damage, and enhancing the nutritional quality of crops.

Front

What is isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
