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 is the primary function of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is ATP and its role in cellular processes?

Back

ATP (adenosine triphosphate) is a molecule that provides energy for various cellular activities, acting as the energy currency of the cell.

Front

What is energy transformation in photosynthesis?

Back

Energy transformation in photosynthesis refers to the conversion of light energy into chemical energy stored in glucose.

Front

What is enthalpy change in a chemical reaction?

Back

Enthalpy change is the heat content change during a chemical reaction, indicating whether energy is absorbed or released.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C₆H₁₂O₆) and oxygen (O₂).

Front

What is the role of light in photosynthesis?

Back

Light provides the energy required to drive the photosynthesis process, enabling the conversion of carbon dioxide and water into glucose.

Front

What is the significance of oxygen produced in photosynthesis?

Back

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

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.
