Chloroplast

Front

What is the main function of chloroplasts in plant cells?

Back

Chloroplasts are the organelles where photosynthesis occurs, converting light energy into chemical energy in the form of glucose.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

Where does the light-dependent reaction of photosynthesis occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that captures sunlight, which is essential for the light-dependent reactions of photosynthesis.

Front

What is produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP, NADPH, and oxygen as a byproduct.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the light-independent reaction of photosynthesis that uses ATP and NADPH to convert carbon dioxide into glucose.

Front

What are electron carriers in photosynthesis?

Back

Electron carriers are molecules that transfer high-energy electrons from one reaction to another, playing a crucial role in the light-dependent reactions.

Front

What is the significance of the stroma in chloroplasts?

Back

The stroma is the fluid-filled space in chloroplasts where the Calvin Cycle takes place.

Front

Which molecule is not required for the Calvin Cycle?

Back

H2O (water) is not required for the Calvin Cycle.

Front

What is the role of pigments in photosynthesis?

Back

Pigments capture sunlight, which is necessary for the process of photosynthesis.
