Photosynthesis, Cellular Respiration: Standard 6

Front

What is the primary function of photosynthesis in plants?

Back

To convert light energy into chemical energy in the form of glucose.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin cycle (light-independent reactions).

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to facilitate the conversion of light energy into chemical energy.

Front

What is cellular respiration?

Back

The process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the chemical equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

How do photosynthesis and cellular respiration relate to each other?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis, providing electrons and protons for the formation of glucose.

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the survival of aerobic organisms, including humans.
