How does temperature affect the rate of photosynthesis in the Elodea plant?

Back

The rate of photosynthesis increases as temperature increases up to around 25⁰ C and then decreases.

Front

What are the reactants in cellular respiration?

Back

Sugar (glucose) and oxygen.

Front

What is the source of carbon in the sugar molecule produced during photosynthesis?

Back

Carbon dioxide in the air.

Front

How can a scientist measure the rate of cellular respiration of a snail in water?

Back

By counting the carbon dioxide bubbles released into the water.

Front

Define cellular respiration.

Back

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is photosynthesis?

Back

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

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for converting carbon dioxide and water into glucose.

Front

What is the equation for photosynthesis?

Back

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What is the main energy currency of the cell?

Back

Adenosine triphosphate (ATP).
