Photosynthesis and Respiration Middle School

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 the chemical equation for photosynthesis?

Back

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Front

What is the main energy source for life on Earth?

Back

The Sun.

Front

What do plants produce during photosynthesis that is essential for energy?

Back

Sugar (glucose).

Front

What organelle in plant cells is responsible for photosynthesis?

Back

Chloroplasts.

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 is the chemical equation for cellular respiration?

Back

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP).

Front

What organelle in cells releases energy from glucose?

Back

Mitochondria.

Front

What pigment is responsible for the green color in plants?

Back

Chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, which is used to convert carbon dioxide and water into glucose.
