WebDiatoms and Their Unlikely Relatives.... Diatoms are important producers in aquatic food chains. In diatoms, the photosynthetic pigment is yellow, not green. Diatoms convert the products of photosynthesis into oil droplets--an energy reserve the cell can draw on when the sun isn’t shining. But the unique thing about a diatom is its house. WebPennales. The order Pennales is a traditional subdivision of the heterokont algae known as diatoms. [1] [2] The order is named for the shape of the cell walls (or valves or frustules) of pennate diatoms, which are elongated in valve view. The valves may be linear or oval in shape, and usually bear bilaterally symmetrical ornamental patterns. canadian academy of therapeutic tutors
