Carbon Cycle: Photosynthesis and Cellular Respiration

Front

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, and releasing oxygen as a byproduct.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

How does deforestation affect the carbon cycle?

Back

Deforestation increases the level of carbon dioxide in the atmosphere because fewer trees are available to absorb CO2 during photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What are the main reactants of cellular respiration?

Back

The main reactants of cellular respiration are glucose and oxygen.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, carbon dioxide, and water.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon atoms are recycled through the Earth's ecosystems, including processes like photosynthesis, respiration, decomposition, and combustion.

Front

What is the significance of oxygen in the carbon cycle?

Back

Oxygen is produced during photosynthesis and is essential for cellular respiration in most living organisms.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen, thus playing a crucial role in regulating atmospheric CO2 levels.
