The freshwater forms prefer well-aerated water. The marine forms are of world-wide distribution being predominantly represented [...]
In this article we will discuss about the reproduction in pennales. This will also help you to draw the structure and diagram of reproduction in pennales. 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 [...]
