You will use the following experiment to answer question 7 & 8:
A gardener was interested in helping her plants grow faster. When she went to the nursery, she found 3 fertilizers available for her plants. One of those fertilizers, fertilizer A was recommended to her. However, she decided to conduct a test to determine which of the 3 fertilizers, if any helped her plants grow fastest. The gardener planted 4 seeds, each in a separate pot. She used the same type of pot and the same type of soil in each pot. She fertilized one seed with fertilizer A, one with fertilizer B, and one with fertilizer C. She did not fertilize the 4th seed. She placed the pots near one another in her garden. She made sure to give each plant the same amount of water each day. She measured the height of the plants each for 8 weeks and recorded her data.
7. Why didn’t the gardener use fertilizer on the 4th plant?
a. The 4th plant would have to be from a different species that doesn’t react well the fertilizer
b. The 4th plant would be used to compare to the growth of the other plants to see if the fertilizer is effective
c. The gardener made an error. The 4th plant should be given a fertilizer
d. The gardener knew that plants with fertilizer always grow faster
8. What is the MAIN reason for having the same pot, soil, seed, water, and growing environment in this experiment?
a. It’s easier to perform the experiment this way.
b. It’s cheaper to perform the experiment this way
c. By keeping all of these factors the same, the gardener can get a better idea if the fertilizer is actually working.
d. It would actually be a better experiment if the gardener used different water amounts and different soils.
9. Which of the following sequences represent how multicellular life organizes itself?
a. Tissues, organs, organ systems, organisms
b. Cells, tissues, organs, organ systems, organisms
c. Organisms, organs, tissues, cells
