characteristics of protists

Photosynthetic Protists - They are also known as protistan algae or plantlike protists. They are represented by mainly the unicellular algae. These organisms are mostly planktonic and represent the phytoplanktons which account for nearly 80% of the total photosynthetic activity ..

The protozoan protists are also known as animal-like protists. They are represented by unicellular animals which were earlier placed in the phylum Protozoa under Animal kingdom. They are now identified in four groups zooflagellates , sarcodines , ciliates and sporozoan..

Protists can be broadly distinguished into three major groups, namely 1. Photosynthetic protists 2. Slime moulds and 3. Protozoan protists..

Kingdom Protista - The Kingdom Protista includes with a few exceptions, all the unicellular eukaryotic micro-organisms. They are predominantly aquatic where they occur as solitary cells. Some of them may form colonies consisting of similar cells. The protists are regarded as ancestors of ..

These protistans fall under thephylum - Chryosophyta and are commonly called as diatoms . There are more than 5,000 species of diatoms. They are microscopic, unicellular, protistans which represent a major part of phytoplanktons both in fresh water and marine water. Diatoms occur in various shapes ..

The present trend in biology is to follow the five kingdom classification proposed by R.H.Whittaker in the year 1969. Whittaker classified the living organisms into five kingdoms namely. 1. KINGDOM: MONERA (prokaryotic organisms) 2. KINGDOM: PROTISTA (primitive eukaryotic organisms) 3. KINGDOM: MYC..

These protists belong to a division called Pyrrophyta of algae. They are a well defined group of unicellular, photosynthetic forms. Most of them are flagellated and motile but some forms are non-flagellated. Dinoflagellates are mostly marine forms. There are some fresh water forms also. M..
