R.H Whittaker proposed the five kingdom classification in 1969. Those five kingdoms are: Monera, Protista, Mycota (Fungi), Metaphyta (Plantae) and Metazoa (Animalia). It is the most accepted system of modern classification as the different groups of animals are placed phylogenetically.

Binomial nomenclature is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms. The formal introduction of this system of naming species is credited to Swedish natural scientist Carl Linnaeus, effectively beginning with his work ‘Species Plantarum’ in 1753.

Various components of blood are: Plasma, Erythrocytes (Red Blood Cells), Leucocytes (White Blood Cells) and Thrombocytes/Platelets. Monocytes, also known as macrophages, are the largest blood cells in most mammals, measuring 10-15 m in diameter. They are leucocytes. Their nuclei are kidney-shaped and cytoplasm is abundant.
