7H: UNIT 2- Photosynthesis/respiration REVIEW

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is respiration in living organisms?

Back

Respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

Where does respiration occur in cells?

Back

Respiration occurs in the mitochondria of cells.

Front

What is chlorophyll?

Back

Chlorophyll is the green pigment found in plants that is essential for photosynthesis, as it absorbs light energy.

Front

What are stomata?

Back

Stomata are tiny openings on the surface of leaves that allow carbon dioxide to enter and oxygen to exit during photosynthesis.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the raw materials needed for photosynthesis; it is absorbed through the stomata.

Front

What is the role of oxygen in respiration?

Back

Oxygen is used in respiration to help convert glucose into energy, producing carbon dioxide and water as byproducts.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that combines two molecules by removing water, often forming polymers from monomers.

Front

What is polymerization?

Back

Polymerization is the process of combining small molecules (monomers) to form larger, more complex molecules (polymers).
