All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. A second kind of chlorophyll is chlorophyll b, which occurs only in green algae and in the plants.A third form of chlorophyll which is common is (not surprisingly) called chlorophyll c, and is found only in the photosynthetic members of the Chromista as well as the dinoflagellates.ore important than their reflection of light is the ability of pigments to absorb certain wavelengths. Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs --organisms which make their own food using photosynthesis.
Chlorophyll is ___ in color; a group of marine organisms that contains chlorophyll are called ___ green; phytoplankton Kelp belongs to which of the following types of organisms? macroscopic algae: Dinoflagellates are important examples of ___ that are often associated with ___ phytoplankton; red tides: Late one night as you flipping channels on TV... domoic acid: photosynthesis in tropical waters is limited by which of the following factors
