Summary Introduction
Introduction: Protist is a microscopic organism that belongs to the kingdom “Protista”. These have been classified into various categories depending upon their mode of nutrition. They can reproduce both sexually and asexually. Protists that are capable of performing photosynthesis are termed as photosynthetic protists.
