Make a hypothesis about which part of the light spectrum causes the most plant growth and which part of the
light spectrum causes the least plant growth. Assume that all conditions other than the color of the light are the
same for each seed as it grows: the soil, moisture, viability of the seed, etc. State your hypothesis on your lab
worksheet. Example: If a plant is grown under color of light then the plant will grow well. However, if
the plant is grown under color light then the plant will not grow well.

The suitable words will be -

Red and Blue   Green

Explanation:

Make a hypothesis about which part of the light spectrum causes the most plant growth and which part of the light spectrum causes the least plant growth. Assume that all conditions other than the color of the light are the same for each seed as it grows: the soil, moisture, viability of the seed, etc. State your hypothesis on your lab worksheet. Example: If a plant is grown under Red and Blue color of light then the plant will grow well. However, if the plant is grown under Green color light then the plant will not grow well. All the VIBGYOR color is mixed all together and forms the White color. Plants are green because chlorophyll reflects the green light and absorbs the other light spectrums. If the Blue light spectrum is absorbed then the plant will grow the most and if the Greenlight spectrum is absorbed then the plant will grow the least.
