Suzie Q wants to know how different colors of light effect the growth of plants. She believes that plants can survive the best in white light. She buys 5 ferns of the same

species, which are all approximately the same age and height. She places one in

white light, one in blue light, one in green light, one in red light and one in the

closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a

day for 2 weeks. After the two weeks, Suzie observes the plants and measurements.

4. What measurements could Suzy make to determine how different colors of light

affect the growth of plants?

Suzie can measure the HEIGHTS of the plants in metres (m) or centimeters (cm)

Explanation:

According to this question, Suzie Q wants to know how different colors of light effect the growth of plants. She sets up the experiment by exposing 5 ferns of the same species to different colors of light (white, blue, green, red).

After ensuring that some variables called constants like same 20 mL of water, same fertilizer (miracle-grow) etc are the same for all ferns, She then measures the growth of each fern placed under different colors of light.

The independent variable in this experiment is the different colors of light while the dependent variable is the growth of the plants. This question is asking for how Suzie could measure the dependent variable (growth). Suzie can measure the growth of the ferns placed under different colors of light by RECORDING THE HEIGHTS OF EACH FERN IN cm or m.

i have to report this, it doesn't relate to biology

what is this saying?
