100
The smallest unit of matter.
What is an atom?
100
An element found in water and carbon dioxide. It is used to create glucose.
What is oxygen?
100
The complex process by which carbon dioxide and water are converted into glucose and oxygen by green plants, using energy from the sun and chlorophyll.
What is photosynthesis?
100
The organelle that contains chlorophyll.
What is chloroplast?
100
The part of the experiment that varies or changes.
What is independent variable?
200
A substance, made of atoms, that cannot be broken down into smaller substances.
What is an element?
200
An element found in water, but not carbon dioxide. It is used to create glucose.
What is hydrogen?
200
A simple sugar found in plant tissues. It is a product of photosynthesis.
What is glucose?
200
The green pigment of plants that traps the energy of sunlight for photosynthesis.
What is chlorophyll?
200
The part of part of the experiment being measured.
What is the dependent variable?
300
A substance created when two or more atoms form chemical bonds with each other. It doesn't matter if the atoms are the same or are different from each other.
What is a molecule?
300
An element found in carbon dioxide, but not water. It is used to create glucose.
What is carbon?
300
A molecule made of two oxygen atoms. It is a product of photosynthesis.
What is oxygen?
300
This organelle combines oxygen with glucose to form ATP or energy for the body.
What is mitochondria?
300
A prediction or inference made based on what will happen to the dependent variable when the independent variable is changed.
What is a hypothesis?
400
A substance that is present at the start of a chemical reaction (an ingredient).
What is a reactant?
400
A molecule made of carbon and oxygen atoms. It is a reactant in photosynthesis.
What is carbon dioxide?
400
The energy source for photosynthesis. It is used to break up the bonds of the reactants to form the products.
What is sunlight?
400
Holes in plant leaves that allow carbon dioxide to enter and oxygen to leave.
What is stomata?
400
The steps to carry out the experiment.
What is the procedure?
500
A substance obtained from another substance as a result of a chemical reaction (a result).
What is a product?
500
A molecule made of hydrogen and oxygen atoms. It is a reactant in photosynthesis.
What is water?
500
Photosynthesis Chemical Equation.
What is 6CO2 + 6H2O -- sunlight --> 1C6H12O6 + 6O2?
500
The part of the plant that absorbs water and minerals from the soil.
What are roots?
500
The answer to your original question. Indicates whether your hypothesis was correct or not.
What is the conclusion?
