A scientist wants to determine the best light wavelength for growing plants. He grows plants in four test groups as shown in the table below. What, if anything, was wrong with the experiment?

He should only change the wavelength of light for each group.

He should only grow one plant in each group.

He should add a control group with a CO2 level of zero ppm and a light intensity of zero percent.

There is nothing wrong with the experiment.

How do plants get the carbon dioxide they need for photosynthesis?

Carbon dioxide enters their leaves from the atmosphere.

Carbon dioxide is produced in a chemical reaction inside their chloroplasts.

Carbon dioxide enters their roots from the soil.

Carbon dioxide is produced in a chemical reaction inside their mitochondria.

What do plants do with most of the oxygen produced in photosynthesis?

They release most of the oxygen into the atmosphere.

They use most of the oxygen to make more glucose.

They release most of the oxygen into the soil.

They use most of the oxygen to produce carbon dioxide.

Why is photosynthesis important to plants?

It produces a simple sugar they need for cellular respiration.

It prevents the buildup of too much water in their cells.

It produces the carbon dioxide they need for plant digestion.

It breaks down a simple sugar into a type of energy their cells can use

Photosynthesis is important to us and all other animals because

oxygen, which animals breathe, is released as a byproduct. and glucose is used to produce ATP

carbon dioxide, which animals need for cellular respiration, is released as byproduct.

it prevents any of the sun's energy from being absorbed by animals' skin.

it prevents carbon dioxide from destroying animals' habitats.

Animals, including humans,

get glucose from the food they eat.

get glucose from the sun's energy.
