In this article we will discuss about:- 1. Occurrence of Vaucheria 2. Thallus Structure of Vaucheria 3. Affinities. Occurrence of Vaucheria: Vaucheria is represented by 54 species of which about 19 species are found in India. Vaucheria is found mostly in fresh water but about six species are marine and some are terrestrial found on moist soil. The terrestrial species [...]
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 [...]
