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 is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

Front

What role do chloroplasts play in plants?

Back

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

Front

Why do plants appear green?

Back

Plants appear green because chlorophyll reflects green light and absorbs other wavelengths of light for photosynthesis.

Front

What is the main source of energy for life on Earth?

Back

The main source of energy for all life comes from the sun.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

Front

What is the function of chlorophyll?

Back

Chlorophyll is a pigment that absorbs light energy, primarily in the blue and red wavelengths, and is essential for photosynthesis.

Front

What are the products of cellular respiration?

Back

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

Front

What is the significance of the sun in photosynthesis?

Back

The sun provides the light energy necessary for photosynthesis to occur, enabling plants to produce glucose.
