Photosynthesis & Respiration Review

Front

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.

Front

What are Autotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What are Heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy, such as animals and fungi.

Front

What are Reactants in a chemical reaction?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are Products in a chemical reaction?

Back

Products are the substances that result from a chemical reaction after the reactants have been transformed.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is used in cellular respiration to help convert glucose into energy (ATP) and produces carbon dioxide and water as byproducts.

Front

What is the relationship between Photosynthesis and Cellular Respiration?

Back

Photosynthesis generates oxygen and glucose, which are used in cellular respiration to produce energy, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

How do plants obtain energy?

Back

Plants obtain energy by producing food through photosynthesis, using sunlight, carbon dioxide, and water.

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that stores and transfers energy within cells, acting as the energy currency of the cell.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that captures light energy from the sun, which is essential for photosynthesis.
