Some students grew sunflowers in the biology laboratory. After three weeks they measured the height of each plant. The following figure shows the conditions of the experiment:

a. The factor changing among groups = The color of the light

b. The independent variable in this experiment = Color of light

c.  The quantity measured at the end of the experiment = The height of the plant

d. The dependent variable is the height to which the plants grow

e. The control group is the Plant Group C, because they are subjected to normal light

f. The parts of the experiment kept constant are;

Temp

Humidity

Water Daily

Daily Light Exposure

g. The amount of nutrient available and atmospheric gases

h. The growth rate of plant is dependent on the color of the light in which the plant grows
