During an experiment, Amara covered a part of a leaf of a green plant with dark paper and kept the plant in sunlight.

Which statement best describes the result of this experiment?

The covered part will not receive sufficient water to make food.
The covered part will not make food in the absence of sunlight.
The uncovered part will have more chlorophyll than the covered part.
The uncovered part will receive more oxygen than the covered part.

Plants need sunlight in order to make food. If the leaf is covered then that part cannot make food. The answer is B)The covered part will not make food in the absence of sunlight.

The others are wrong because: Water is drawn up from the stem, so the covered leaf don't be affected. Chlorophyll is the green pigment that will be present in the leaf no matter if it's covered or uncovered. Oxygen will still reach the leaf because the paper doesn't stop it.

The second one, The covered part will not make food in the absence of sunlight, is correct.

Hope this was of help, have a great day :)
