100
Which part of the plant absorbs nutrients and water?
The root system
100
In the light, do plants absorb carbon dioxide or release carbon dioxide?
Plants release CO2 in the light
100
Which 3 types of atoms are found in glucose?
carbon, hydrogen, and oxygen
200
Which part of the plant is shown here under a microscope?
The roots
200
In the light, do plants absorb oxygen or release oxygen?
Plants release oxygen in the light
200
What two molecules does photosynthesis make?
Glucose and oxygen
300
Which parts of the plant are responsible for moving water and other substances, like the pipes of a house?
Shoot system (stem and veins) or vascular system
300
In the dark, what happened to the amount of oxygen in the water when only plants were present?
In the dark, plants took oxygen out of the water, so the oxygen decreased
300
Photosynthesis uses sunlight and what two molecules (inputs)?
Carbon dioxide and water
400
What does this image show under the microscope?
Stomata and plant cells
400
Did the snails absorb oxygen or produce oxygen?
The snails absorbed oxygen because the amount of O2 decreased
400
How does carbon dioxide get into the plant?
CO2 enters through the stomata
500
What are stomata? Where are they found?
Stomata are tiny pores on the bottom of a leaf. They let gases in and out.
500
Did the snails produce carbon dioxide or absorb carbon dioxide?
The snails produced carbon dioxide
500
When the stomata are more open, what happens to the amount of CO2 the plant absorbs?
More open stomata = more CO2 absorption
