Photosynthesis Quiz

Global warming is gradual increase in Earth's temperature due increase in greenhouse gases.

• True

• False

Rate of photosynthesis is affected by

• Carbon dioxide

• Temperature

• Intensity of light

• all of the above

One common method to measure the rate of photosynthesis is to use an aquatic plant and measure the rate of bubbles produced. What gas is collected in the test tube?

• Oxygen

• Carbon dioxide

• Steam

• Air

Why use aquatic plant?

• They are greener and hence can produce more food.

• Because the experiment requires gas to be collected by displacing water.

• Water has more carbon dioxide than air.

• It just makes sense to do so.

Why does the rate of photosynthesis stops increasing after a certain point?

• There are other factors which affect photosynthesis

• CO2 is a limiting factor

• Temperature is a limiting factor.

• All of the above

All living things need to respire.

• True

• False

Protozoan are the primarily producers in the food chain.

• True

• False
