Description:

Plants as producers perform the process of photosynthesis. Chlorophyll is the molecule – key to photosynthesis. What happens on a planet without enough light? Why the leaves of plants, are green? Are they green on any other planet? To answer all these questions we studied the chlorophyll. With the spectroscope we saw that absorbs red and blue, and reflects the green. With a clever experiment – game showed why the sky on Earth is blue and we associated this fact with the behavior of chlorophyll. We studied the growth of plants under radiation of different wavelengths, as well as in conditions of limited or poor lighting.
