What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

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. It occurs in the mitochondria of cells.

Front

What is the main difference between photosynthesis and cellular respiration?

Back

Photosynthesis uses carbon dioxide and water to produce glucose and oxygen, while cellular respiration uses glucose and oxygen to produce carbon dioxide and water.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food from inorganic substances, typically through photosynthesis or chemosynthesis.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms or organic matter for energy.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is a molecule that carries energy within cells, providing the energy needed for various cellular processes.

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 (ATP).

Front

What is passive transport?

Back

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

Front

What role does carbon dioxide play in photosynthesis?

Back

Carbon dioxide is one of the raw materials used in photosynthesis to produce glucose and oxygen.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen is a key reactant in cellular respiration, allowing cells to convert glucose into ATP, carbon dioxide, and water.
