Thallus Structure of Navicula (With Diagram)

In this article we will discuss about the thallus structure of Navicula with the help of suitable diagrams. Thallus is represented by a iso-bilaterally symmetrical diploid unicells. Structurally, it can be differentiated into two parts - A siliceous cell wall (called frustule) and the protoplast. The cell wall is made of pectic substances which are impregnated with silica (SiO2). Cell [...]

Life Cycle of Navicula (With Diagram)

In this article we will discuss about the vegetative and sexual methods of reproduction that occur in the life cycle of Navicula. Vegetative Reproduction: It takes place by the mitotic cell division or fission. Successive cell division takes place very rapidly at night. Presence of aluminium-silicate in water is essential for cell division to occur. As the cell division starts, [...]
