Photosynthesis and Cellular Respiration Concepts

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.

Front

What are Autotrophs?

Back

Autotrophs are organisms that can produce their own food using light, water, carbon dioxide, or other chemicals. They are the primary producers in an ecosystem.

Front

What are Heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms (plants or animals) for energy.

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

How are Photosynthesis and Cellular Respiration connected?

Back

The products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and vice versa.

Front

What is the role of Chloroplasts in plants?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place, containing chlorophyll that captures light energy.

Front

What is the equation for Photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2 (Carbon dioxide + Water + Light energy → Glucose + Oxygen).

Front

What is the equation for Cellular Respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP (Glucose + Oxygen → Carbon dioxide + Water + Energy).

Front

What is the significance of Oxygen in Photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis and is essential for the survival of aerobic organisms.

Front

What is the significance of Carbon Dioxide in Photosynthesis?

Back

Carbon dioxide is one of the key reactants in photosynthesis, used by plants to produce glucose.
