Let’s take a look at diatoms under the microscope.
Diatoms are photosynthetic organisms referred to as algae with a length/diameter of between 2 and Graphs showing abundance of the diatom Paralia sulcata in stratigraphic sections at the Redtail and Oyster localities, Niawiakum River 37 Diagram of .The diatoms are one of the largest and ecologically most significant groups of organisms on Earth. They are also one of the easiest to recognize, because of their unique cell structure, silicified cell wall and life .
ADVERTISEMENTS: In this article we will discuss about the reproduction in basillariophyta. This will also help you to draw the structure and diagram of reproduction in bacillariophyta.
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 [ ].
A dead Navicula diatom imaged in phase contrast, clearly showing the markings on the frustule. The green filament immediately above is (most likely) of the blue-green alga Oscillatoria.
Phase Contrast. x Another dead Navicula diatom, this time shown in brightfield illumination. Click for a diagram of Navicula.
Brightfield, x 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. Diatoms may occur in such large numbers and be well preserved enough to form sediments composed almost entirely of diatom frustules (diatomites), these deposits are of economic benefit being used in filters, paints, toothpaste, and many other applications.Diatoms: Characteristics, Occurrence and ReproductionLabeled Diatom Diagram – Engine Diagram And Wiring Diagram
