Concept 4: Photosynthesis

Front

What molecule absorbs sunlight for photosynthesis?

Back

Chlorophyll is the molecule that absorbs sunlight, allowing plants to convert light energy into chemical energy.

Front

Where does the Calvin Cycle occur?

Back

The Calvin Cycle occurs in the stroma of chloroplasts, where carbon dioxide is fixed into glucose.

Front

What is the organelle that contains the chlorophyll used in photosynthesis?

Back

The chloroplast is the organelle that contains chlorophyll and is responsible for photosynthesis.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are oxygen and glucose, which are produced during the process.

Front

Which best describes light-independent reactions?

Back

Light-independent reactions utilize the energy stored in ATP and NADPH to convert carbon dioxide into glucose.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

The primary function of chlorophyll is to capture light energy from the sun, which is essential for photosynthesis.

Front

What is the overall equation for photosynthesis?

Back

The overall equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What role do thylakoids play in photosynthesis?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is the significance of the stroma in photosynthesis?

Back

The stroma is the fluid-filled space in chloroplasts where the Calvin Cycle takes place, synthesizing glucose from carbon dioxide.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings called stomata on their leaves.
