Understanding Plant Processes

What was the initial prediction made by most students about water levels in the plant experiment?

• Water would evaporate completely

• Water levels would remain constant

• Water would decrease

• Water would increase

In the carbon-oxygen cycle, what do plants release as a byproduct?

• Carbon dioxide

• Nitrogen

• Oxygen

• Methane

What form can oxygen take when released by plants?

• Liquid

• Solid

• Water vapor

• Carbon monoxide

What was the purpose of the longer experiment conducted by another student group?

• To measure the growth rate of plants

• To observe changes in oxygen levels over time

• To test different types of soil

• To see how plants react to different temperatures

What additional factor did the other student group measure in their extended experiment?

• Light exposure

• Amount of water used

• Soil pH levels

• Temperature changes
