Photosynthesis - Biology

Front

What are stomata?

Back

Tiny pores in the leaf responsible for gas exchange.

Front

What do plants need for photosynthesis?

Back

Carbon dioxide.

Front

In which organelles does photosynthesis occur?

Back

Chloroplasts.

Front

What is the primary function of the light reactions of photosynthesis?

Back

To produce ATP.

Front

What are the products of photosynthesis?

Back

Oxygen (O2) and glucose.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is essential for photosynthesis.

Front

What is the overall equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to produce ATP and NADPH, while light-independent reactions (Calvin cycle) use ATP and NADPH to synthesize glucose.

Front

What is the Calvin cycle?

Back

A series of biochemical reactions that occur in the stroma of chloroplasts, using ATP and NADPH to convert carbon dioxide into glucose.

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis produces oxygen and organic compounds, which are essential for the survival of most life forms.
