✳PROTOZOA...

• It includes eukaryotic unicellular and simple multicellular organisms.
• They are mostly heterotrophic.
• They are mostly plant like, as they lack chlorophyll and cell wall.
• They are mostly fresh water organisms.
• Euglena is an exception which has both plant and animal's characteristics.

Examples - Amoeba, Paraemacium and Euglena

✳FUNGI

• It includes eukaryotic multicellular heterotrophs which are absorptive in their nutritional mode e.g. mushrooms.
• Most fungi are decomposers. They live on organic materials, secrete digestive enzymes and absorb small organic molecules formed by the digestion of enzymes.
• They have peculiar way of digesting food, they release enzyme outside and consume it .
• They have a cell wall made up of chitin.

Examples- Rhizopus, Yeast, Slime moulds

✳ALGAE

• Algae are unicellular, colonial or simple multicellular.
• They resemble plant cells with cell walls and chlorophyll in chloroplasts.
• Simple multicellular means that they do not have multicellular sex organs and do not form embryos during their life cycles.
• They can form lichens, with associations with fungi and higher plants.

Examples- Volvox, Chara, Spirogyra

✳VIRUS

• Viruses are at the borderline of living and nonliving. Due to their crystalline nature, they are considered non-living.
• They are acellular i.e. they do not have cellular organization yet show some characters of living organisms (e.g. they possess DNA).
• Viruses contain either RNA or DNA, normally encased in a protein coat.
• They reproduce only in living cells, where they cause a number of diseases.
• They are not considered as organisms and thus are not included in the five-kingdom classification system.

Examples- Corona virus, HIV virus, Tobacco mosaic.
