Draggable itemCorresponding Item
Independent Variable
What proportion of a mixture is a certain kind of substance
Concentration
Factors in an experiment that can be changed
Control Variables
The variable in an experiment that you choose to change in order to measure the effect it has on other variables
Variables

Draggable itemCorresponding Item
Magnesium
structure with many proteins and chemicals that work together to complete the process of photosynthesis
Carbon Dioxide
Chemical that absorbs energy from the sun to power photosynthesis
Chloroplast
all the chemicals a plant or organism needs to grow
Nitrogen
reactive gas produced by plants during photosynthesis
Water
gas absorbed by plants which provides most of the mass in a growing plant
Nutrients
sugar produced by photosynthesis which can provide energy or materials needed to produce many other chemicals
Glucose
chemical which provides Hydrogen to a plant and brings other nutrients up from the roots necessary for growth
Oxygen
just one of these atoms is needed to make every chlorophyll molecule
Chlorophyll
most common gas in the atmosphere, but plants can only absorb needed supply through roots after it is combined with Oxygen by bacteria or animals
