Plant Growth Effects and Plant Tests,the density of photosynthetic plants on the earth’s surface and the efficiency with which they can absorb light and photosynthesize throughout all the seasons. In contrast, a highly efficient C. plant, such as corn, may utilize 5% of incident radiant energy during its most rapid period of growth.
