Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy stored in glucose.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, primarily converting carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment found in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose (C6H12O6).

Front

What is the importance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food (e.g., plants), while heterotrophs are organisms that consume other organisms for energy (e.g., animals).

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split during the light-dependent reactions to release oxygen.
