Chapter 9: Photosynthesis

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 the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound compartments inside chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

Front

What is the stroma?

Back

The stroma is the fluid-filled space surrounding the thylakoids in chloroplasts where the light-independent reactions (Calvin cycle) occur.

Front

What is the light-dependent reaction?

Back

The light-dependent reactions are the first stage of photosynthesis, occurring in the thylakoids, where sunlight is converted into chemical energy in the form of ATP and NADPH.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent reaction of photosynthesis that takes place in the stroma, where carbon dioxide is fixed into glucose using ATP and NADPH.

Front

What is ADP?

Back

ADP stands for adenosine diphosphate, a lower energy molecule that can be converted into ATP by adding a phosphate group.

Front

What is ATP?

Back

ATP stands for adenosine triphosphate, a high-energy molecule that stores and provides energy for various cellular processes.

Front

What gas do plants release during photosynthesis?

Back

Plants release oxygen as a byproduct of photosynthesis.
