Experimental Design
100
The compound other than oxygen that is produced during photosynthesis.
What is glucose?
100
This is where cellular respiration occurs.
What is the mitochondria?
100
CO2
What is carbon dioxide?
100
Petroleum, coal, and natural gas.
What are the main types of fossil fuel?
100
This is the variable that is changed or manipulated in an experiment.
What is the independent variable?
200
The part of the leaf where photosynthesis occurs.
What are the cholorplasts?
200
This is how many carbon dioxide molecules are produced.
What are 6?
200
This is a sink for carbon that covers a vast majority of the Earth's surface.
What is the ocean?
200
Carbon dioxide, methane, water vapor, and nitrous oxide.
What are the major greenhouse gases?
200
This is variable that is measured in an experiment.
What is the dependent variable?
300
Most of a plant's mass if composed of this.
What is carbon dioxide?
300
Organisms that respire by breaking down dead/decaying plants and animals.
What are decomposers?
300
When this dies, it is added to the soil releasing carbon.
What is a plant?
300
The increase of surface temperatures due to excess amounts of greenhouse gases.
What is global warming?
300
A group to which experimental groups are compared to determine effective variables.
What is a control group?
400
These structures on the underside of the leaf open and close to let gases out of the plant.
What are the stomata?
400
oxygen and glucose (think about the respiration equation)
What are the reactants in the respiration equation?
400
The burning of these adds excess carbon dioxide into the atmosphere, throwing off the natural balance of the carbon cycle.
What are fossil fuels?
400
During this reaction, a hydrocarbon (generally a type of fuel) combines with oxygen to produce water and carbon dioxide.
What is combustion?
400
There are several of these in an experiment to ensure that the experiment is valid, and it never contains the independent variable.
What are controls?
500
The chemical in plants that absorbs the sun's energy for photosynthesis.
What is chlorophyll?
500
The type of radiation to greenhouse gases absorb.
What is infrared radiation?
500
An if...then statement that states what you expect to happen as a result of an experiment.
What is a hypothesis?
