Identify TWO conditions that are the same in each trial

Plant and number of leaves

Water level

Amount of light the plant receives (mesh)

Number of gas bubbles produced

Identify the one condition that has been changed in the four experiments

Plant type

Amount of water

Amount of light the plant receives

The beaker size

How does the mesh screen affect the rate of gas production?

plants exposed to more light make more oxygen gas bubbles

the mesh screen does not affect gas production

plants exposed to less light make more carbon dioxide

plants exposed to more light make more hydrogen gas

What process is occurring in the plant's cells?

transcription

DNA replication

membrane transport

photosynthesis

What gas is the plant producing?

oxygen

carbon dioxide

nitrogen

hyrodgen

What source of energy is the plant using?

glucose

the light

ATP

magic

How could you measure the rate of gas production?

count the leaves on the plant

count the gas bubbles

measure the sunlight

use a scale

Identify THREE environmental factors that may factor the affect rate of gas production

The plants labeled A, B, C, and D all have the same amount of leaves. How many leaves are on each plant?
