Chlorophyll is the chemical compound that plants use to absorb the sun's energy and use it to produce their own food. Phytoplankton are microscopic organisms in the oceans that contain chlorophyll, and through the process of photosynthesis, produce most of the oxygen for the planet. However, some types of phytoplankton are also dangerous to human health because they release toxins. When these types ... Full description.
