What kinds of things perform photosynthesis?
plants

What kinds of things perform cellular respiration?
all living things
100
What are reactants?
the starting materials in a chemical reaction
100
What is the purpose of a scatterplot graph?
explain the relationship/correlation between two variables
100
What is glucose?
sugar
200
In what organelle does photosynthesis take place?
chloroplast
200
In what organelle does cellular respiration take place?
mitochondria
200
What are products?
the ending materials that are created in a chemical reaction
200
What is a best fit line?
a line that best approximates the trend of the data
200
What is yeast?
unicellular fungus
300
What is chlorophyll?
a green pigment; captures/absorbs energy from the sunlight
300
What waste product of cellular respiration causes pizza dough and bread to rise?
carbon dioxide
300
What does an arrow represent in a chemical reaction?
yields; reacts to form

Interpret this graph.
As the number of hours of TV each week increases, GPA (grade point average) decreases. This is a negative correlation.

Give an example of two variables that have a positive correlation.
*as height increases, weight increases
*as daily temperature increases, more people go on vacation
*the more you study, the higher your grades
400
What is the chemical equation (in words) for photosynthesis?
carbon dioxide + water + energy from sunlight --> oxygen + glucose
400
What is the chemical equation (in words) for cellular respiration?
glucose + oxygen --> carbon dioxide + water + energy
400
Explain the structure/format of a chemical equation.
Reactants are on the left with + sign in between individual reactants. Products are on the right side with + sign in between individual products. There is an arrow after the reactants pointing towards the products.

Explain the difference between a positive correlation, negative correlation, and no correlation on a scatterplot graph.
Positive: one variable increases and the other also increases
Negative: one variable increases and the other variable decreases
No Correlation: no relationship between the variables; random
400
Give an example of two variables that have a negative correlation.
*the more days you are absent, the lower your grade on the test
*the colder the daily temperature, the more snow
*the older you are, the fewer car accidents you have
500
What is the function of the chloroplast and therefore photosynthesis?
convert energy from the sun into food for the plant
500
What is the function of the mitochondria and therefore cellular respiration?
break down food to release energy to power all activities
500
What is a chemical reaction?
A chemical reaction is a process in which substances are changed into new substances (the molecules are chemically rearranged).
500
Explain how you determine which variable goes on each axis in a scatterplot graph.
The manipulated/independent variable is what the scientist intentionally changes. This goes on the x-axis. The responding/dependent variable is what changes because of the manipulated variable and is what is measured/observed. This goes on the y-axis.

What is the relationship between photosynthesis and cellular respiration?
They are opposite reactions. The reactants of one are the products of the other and vice versa.
