Photosynthesis and Cellular Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

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 are autotrophs?

Back

Autotrophs are organisms that produce their own food from sunlight or chemical energy, such as plants and some bacteria.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy, such as animals and fungi.

Front

What is the role of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) provides the energy needed for the synthesis of carbohydrates during the photosynthesis process.

Front

What is the main byproduct of photosynthesis?

Back

The main byproduct of photosynthesis is oxygen, which is released into the atmosphere.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP).

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the air through small openings in their leaves called stomata.

Front

What is the significance of cellular respiration?

Back

Cellular respiration is significant because it provides energy (ATP) that is essential for all cellular processes and functions.
