Diversity in Living Organisms

In this topic, we will learn about the classification of living organisms. Classification makes it easy and more convenient to study characteristics. The most basic characteristics include the kind of cells, organisms are made up of.

This topic discusses that living things are characterized on the basis of their body design and its function. The classification of life forms is related to their evolution. Based on this, the organisms can be of primitive type or advanced type.

The hierarchy of classification includes Kingdom, phylum, class, order, family, genus, and species. We will learn that living organisms are classified into broad categories called kingdoms. It covers the details of 5 kingdoms proposed by Whittaker.

This topic gives brief information about the kingdom Plantae. We will learn that this kingdom comprises the multicellular eukaryotic organisms with cellulosic cell walls. These organisms are photoautotrophs and use chlorophyll for photosynthesis.

This topic introduces us to the kingdom Animalia. The kingdom comprises the multicellular eukaryotic organisms without the cell walls. It covers the details of heterotrophs, which depend upon green plants for their food.
