Biological Classification Biology Class 11th Chrysophytes Kingdom Protista


In this article we will discuss Chrysophytes

In this article, we will discuss Chrysophytes. So, let’s get started.


This group includes diatoms and golden algae (desmids). They are found
in fresh water as well as in marine environments. They are microscopic
and float passively in water currents (plankton). Most of them are photosynthetic. In diatoms the cell walls form two thin overlapping shells,
which fit together as in a soap box. The walls are embedded with silica
and thus the walls are indestructible. Thus, diatoms have left behind large amount of cell wall deposits in their habitat; this accumulation over billions of years is referred to as ‘diatomaceous earth’. Being gritty this soil is used in polishing, filtration of oils and syrups. Diatoms are the chief producers’ in the oceans.
