Answer:

  Five kingdom classification of living organism was proposed by Whittaker (1959). Linnaeus proposed the hierarchical system of classification which states that species are the smallest unit of classification. The first kingdom classification given by Whittaker is kingdom-Monera which includes prokaryotic cells (e.g.. bacteria) and blue-green algae.) second kingdom in classification is Protista which are unicellular eukaryotic organisms including protozoan's (Paramecium') and algae. Third Kingdom is fling' which are multiceilular organisms. Fungi are multinucleate, do not possess chlorophyll and depends on others for their food (i.e., heterotrophy). Fungi form a network of hyphae which are called as mycelium. These helps in the absorption of mineral from the substrate. There are multicellular and can be seen without microscope. Yeast are the fungi grouped as moulds helps in the proprieties of bread. There are unicellular fungi. Lichens shows symbiotic association (mutual relationship) between algar and fungi which co-exist for mutual benefit,
