Nutrition In Unicellular Organisms
Unicellular organisms exhibit diverse nutritional strategies. These strategies can involve simple osmosis and diffusion or bit complex methods like phagocytosis or pinocytosis. Organisms that belong to the categories of autotrophs can prepare their own food. These groups include photoautotrophs like unicellular algae or cyanobacteria and chemoautotrophs like archaea and certain bacteria. Other heterotrophic unicells can exhibit varius modes of nutrition like saprotrophism, parasitism, etc. Some organisms are mixotrophs and can exhibit both autotrophic and heterotrophic mode of nutrition. The most common example of such organisms is Euglena.
Unicellular Organisms
Organisms that consist of a single cell are referred to as unicellular organisms. All living organisms are made up of cells. They can be composed of a single cell or multiple cells. They include bacteria, archaea, protozoans, unicellular algae, and yeasts. These organisms exhibit high adaptability to the environment and have developed uniquely advanced features to resist adversities despite having such simple body plans. Unicellular organisms have a significant ecological impact and are also used in several different fields of scientific and industrial research.
