In two separate boating incidents, one as a teenager on the Mississippi River and one on the Great Lakes, President Lincoln got his boats stuck in shallow waters, known as shoals.. These two experiences inspired Lincoln to invent a solution to help him navigate his boat through shallow waters.
Algae are simple plants. The biggest similarity with more  'regular' lants is that they both contain chlorophyll    Green algae and plants are sister taxon, that is, tâ¦hey share a  common ancestor.    For this reason, they both have double membrane bound plastids that  contain chlorophyll a and b.
Other Pigments. There are other pigments found in algae that are similar to chlorophyll, though they do not directly capture sunlight. One example is carotenoid, which is a brown pigment (and is found in brown algae which, similar to dinoflagellates, can cause an algal bloom).dditionally, some types of algae have chlorophyllin and phycobilins, which are water-soluble salt derived from chlorophyll used to help capture sunlight (though photosynthesis does not occur in either one), and which are also found in the chloroplast.
