Lab Flashcard: Rate of Photosynthesis

Front

What is the main product of photosynthesis that causes leaf discs to float?

Back

Oxygen

Front

What do plants need for photosynthesis?

Back

Carbon dioxide

Front

How does carbon dioxide enter the leaf of a plant?

Back

Through the stomata

Front

What was the purpose of cutting out leaf discs in the lab?

Back

So they were all the same size

Front

What is the pigment in chloroplasts that performs photosynthesis?

Back

Chlorophyll

Front

What is photosynthesis?

Back

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

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and light-independent reactions (Calvin cycle).

Front

What role does sunlight play in photosynthesis?

Back

It provides the energy needed to convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.
