Photosynthesis and Respiration

Front

What is photosynthesis?

Back

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

Front

What is respiration?

Back

Respiration is the biochemical process in which cells break down glucose and other organic molecules to release energy, typically in the form of ATP (adenosine triphosphate).

Front

What is the main purpose of photosynthesis?

Back

The main purpose of photosynthesis is to convert light energy into chemical energy stored in glucose, which can be used by the plant for growth and energy.

Front

What is the main purpose of respiration?

Back

The main purpose of respiration is to release energy stored in glucose for use by the cell to perform various functions.

Front

What is ATP?

Back

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

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O), which are converted into glucose and oxygen.

Front

What are the products of respiration?

Back

The products of respiration are carbon dioxide (CO2), water (H2O), and ATP (energy).

Front

What organisms perform photosynthesis?

Back

Photosynthesis is performed by plants, algae, and some bacteria.

Front

What organisms perform respiration?

Back

Both plants and animals perform respiration to release energy from food.

Front

How does light energy transform during photosynthesis?

Back

During photosynthesis, light energy from the sun is transformed into chemical energy stored in glucose.
