What is the formula for glucose?

1

Click on the three things used to make glucose during photosynthesis.

What gas is made during photosynthesis?

1

The two steps of photosynthesis are the light dependent reaction and

The plant uses glucose used for

The oxygen produced is

1
Plants are considered __________ because they make their own food.
A student investigates the effects of sunlight intensity on the rate of photosynthesis. She places a plant in a closed container. She maintains the concentration of carbon dioxide and temperature (controls) but exposes the plant to different intensities of sunlight. She measures the rate at which oxygen is produced by the plant.

Click on all of the controls of the experiment (hint there are 2)

1

What is the independent variable (what is changed by the scientist)?

1

What is the dependent variable (what was measured)?

1

What happened to the rate of oxygen output as the light intensity increased?

1

What is the relationship between light intensity and the rate of photosynthesis?

A student decides to conduct a second experiment. She investigates the effect of carbon dioxide concentration on the rate of photosynthesis. She changes the concentration of carbon dioxide but keeps the temperature and intensity of light the same. She measures the rate of oxygen produced by the plant.

Click on all of the controls in the experiment (kept the same)

1

What is the independent variable (what the scientist changed)?

1

What is the dependent variable (what was measured)

1

What happens to the oxygen output rate as the amount of carbon dioxide increases?

1

How might oxygen output rate be impacted in this investigation if the light intensity was kept constant at 10% instead of 40%?
