Brown algae will have chlorophyll a and c as well as an accessory pigment that gives them their brown color.They will also store their food in the form of laminarin.Sizes can range from small forms to large multicellular ones. Dinoflagellates are unicellular,photoautotrophic algae that are encased by a shell of cellulose and silicate plates.They also contain chlorophyll a and c and an accessory pigment that gives them their brown color.
