Photosynthesis & 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 are the main structures involved in photosynthesis?

Back

The main structures involved in photosynthesis are chloroplasts, which contain chlorophyll, the pigment 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 role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

Where does cellular respiration occur in cells?

Back

Cellular respiration occurs in the mitochondria of both plant and animal cells.

Front

What are the products of cellular respiration?

Back

The products of cellular respiration are carbon dioxide, water, and ATP (energy).

Front

What gas is released during photosynthesis?

Back

Oxygen is released as a byproduct during photosynthesis.

Front

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for plants and, indirectly, for animals.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis converts light energy into chemical energy (glucose), while cellular respiration converts that chemical energy into usable energy (ATP) for cells.
