Diversity in living organisms

As we have studied about the classification of the organism and the hierarchical order which deals with taxonomy, binomial nomenclature, and the concerned detailing. Now we will move to the discoveries, the kingdom classification and its need in life.

Diversity:

Earth stands for life. A place or heaven where diverse life forms exist. There are about 20 lac organisms known on Earth with a variety of differences in terms of organization, external form, habitat, nutrition and so on.

Five kingdom classification was proposed by Robert Whittaker in 1959,which includes Monera, Protista, fungi, Plantae, and Animalia

• Classification gives us a data that is significant to search, provides a proper systematic manner of species along with the data of their evolution.
•

Carolus Linnaeus is known as the father of the Modern Taxonomy. He proposed a two-kingdom classification in 1758.

• Aristotle gave the classification of animals on the basis of land, water, and air.

• Primitive organisms are those organisms that have ancient body design while advanced organisms are those kinds of organism who have recently acquired body changes.

• Five kingdom classification was proposed by Robert Whittaker in 1959.

Five kingdom classification includes Monera, Protista, fungi, Plantae, and Animalia
• Carl Woese further divided Monera into Archaebacteria and Eubacteria.

The organization inside the cell:

• Prokaryotic cells: cells with no definite nucleus.

• Eukaryotic cells: cells with a definite nucleus.

• The organization of cells in the body:

• Unicellular: singer celled organisms.

• Multicellular: multi-cell organisms.

The category to obtain food:

• Heterotrophs: depends on other organisms for their food.

• Autotrophs: produce their own food.
