Diatoms chlorophyll
WebChlorophyll-a - Phytoplankton contain chlorophyll–a, the primary pigment that absorbs visible sunlight which is a crucial step in photosynthesis. Because some light is absorbed by chlorophyll-a, scientists use satellites to measure the differences in light in the visible wavelengths reflected from the water surface. WebChlorophyll c. This pigment is primarily seen in marine algae. Brown algae, Diatoms and Dinoflagellates show the presence of chlorophyll c. It is an unusual chlorophyll …
