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 stored in glucose, using carbon dioxide and water.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily in the blue and red wavelengths, and is essential for the process of photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

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.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What role do autotrophs play in the ecosystem?

Back

Autotrophs, such as plants, produce their own food through photosynthesis and serve as the primary producers in the food chain.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is a molecule that stores and transfers energy within cells, making it essential for various cellular processes.

Front

How does large-scale logging affect carbon dioxide levels?

Back

Large-scale logging increases carbon dioxide levels in the atmosphere due to reduced carbon absorption by trees.

Front

What is the principle of conservation of mass in photosynthesis?

Back

The principle of conservation of mass states that the mass of the reactants (carbon dioxide and water) is equal to the mass of the products (glucose and oxygen) in photosynthesis.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and rely on consuming other organisms for energy.
