4. Lyngbya 5.As in the previous sampling period, during this cruise a series of stations along the Canadian coastline labeled E in the diagram had a substantially different flora than the rest of the lake.

One half (epitheca) is a remnant from the previous cell division, while the younger half (hypotheca) is the newly formed side. The hypotheca overlaps the epitheca like two halves of a petri dish. Keep in mind that the cutaway diagram of a diatom is a very generalized schematic and cannot adequately describe the variation in all diatoms. As the image of Coscinodiscus shows, diatom

chloroplasts are usually yellowish-brown in color, ranging between yellowish-green and dark brown. Reproduction in Bacillariophyta (With Diagram) Diatom cells multiply usually by a peculiar method of cell division. An increase in the volume of the frustule results in a slight separation of the valves which is followed by mitotic division of the nucleus with the axis of the spindle being parallel to the short axis of the cell to ensure longitudinal division of the protoplast (Fig. 99E). Centric diatoms are more primitive than pennates (diploid nucleus). Many pennales diatoms have a raphe, which is used for secreting mucilage,

which is also used for diatom mobility (benthic) Figure 5. Diagram showing the diatom mobility using raphe. plankton: diatoms and other phytoplankton Some types of microscopic algae are plantlike and live suspended in bodies of water such as oceans. These organisms are called phytoplankton (from the Greek words phyton, meaning “plant,” and planktos, meaning “wandering”). Some examples of planktonic algae include diatoms and dinoflagellates.

Therefore, it is a tremendous aid in the treatment and prevention of aquarium diseases caused from microorganisms such as “Ick,” velvet, tail and fin rot, fungus, flukes, fish lice, etc.
