Photosynthesis and Cellular Respiration

Front

Why are many plants green?

Back

Chlorophyll reflects green light.

Front

What processes can plants use for energy?

Back

Plants can use photosynthesis and cellular respiration.

Front

What are the products of cellular respiration?

Back

CO2, H2O, ATP.

Front

What waste product builds up in muscle cells during heavy exercise?

Back

Lactic acid.

Front

Which formula represents photosynthesis?

Back

6 H2O + 6 CO2 = C6H12O6 + 6 O2.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is cellular respiration?

Back

The process by which cells convert glucose and oxygen into energy, producing CO2 and H2O as byproducts.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, and reflects green light.

Front

What is the equation for cellular respiration?

Back

C6H12O6 + 6 O2 = 6 CO2 + 6 H2O + ATP.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants absorb CO2 from the atmosphere through small openings called stomata.
