Chlorophyll, the pigments in which photosynthesis takes place, is found mainly in the leaves of plants. The greater the amount of leaves, the greater the amount of photosynthetic activity that can take place. This means an increased growth rate. The plants that grew under fluorescent and sunlight continually accumulated more leaves. The plants that grew under the incandescent bulb, however, began losing leaves. They reached their most number of leaves in the middle of the experiment but then began losing them.

Darkness is a direct comparison with plant health. The plants that grew under sunlight were the darkest. They were a dark shade of green. As the plants that grew under fluorescent lighting progressed, they shifted from a medium green colour to a yellowish green colour. The plants that grew under the incandescent bulb, similar to the plants that grew under fluorescent lighting, started off fairly well. But, as the plants progressed, their colour began to “fade”.
