Plant Growth
The following tables contain the observations from a simulated plant growth caused by different colors.

Question 3
Based on the observations of plant growth simulations above, the red color causes the greatest amount of plant growth.
Question 4
Basing on the observations from the table, the green color causes the least amount of growth in plants.
Question 5
A plant absorbs all the colors from the sun but reflects the yellow and green color. According to the observations in the tables, there is consistency with the scientific analogy. The green color has the least average plant growth across all the plants. This implies that the color is least absorbed by the plants hence influences little plant growth. On the other hand, the other colors cause an almost similar plant growth, implying that the more the color is absorbed the more plant growth it causes.
Question 6
I would expect plants to grow higher under white light since it contains a full spectrum of colors. The faster growth of the plants would be as a result of the combination of all the spectrum colors whose effect is greater than individual colors. Therefore, white light is essential for photosynthesis purposes.
