Question

What r the different basis of cladsification

Answer 1

One look at your surroundings will show you what glaring differences and striking similarities are present in all things around you. There is a multitude of life forms that surround you. Not all plants are same and not all animals, same. There is a great deal of variability amongst the living organisms. This is nothing but biological diversity, a term that shows the variety of life on earth.

Classification of organisms is a systematic method of arranging organisms into different groups and subgroups, based on their similarities and their differences.

Advantages of classification

The foremost advantage of classifying organisms is that it makes the study of a wide variety of organisms very easy and convenient. It also shows the interrelationship between various groups. In biology, there is a basic need to identify organisms correctly and place them in the right category. This helps in learning about the large numbers of organisms in an accurate manner. Classifying organisms also helps in increasing the scope of biological sciences.

Types of Classification

Organisms can be classified on the basis of several different factors. According to this, the different factors include the nature of the cell; the mode of nutrition seen in organisms and also based on the body organization. Broadly, the following are the different types of classification.

1] Cell nature –Are cells Prokaryotic or Eukaryotic?



Depending on whether cells of the organisms are prokaryotic or eukaryotic, organisms can be classified into two categories. Prokaryotic organisms have prokaryotic cells, in which nuclei and cell organelles are not demarcated clearly. Eukaryotic organisms, on the other hand, have eukaryotic cells, which have a clear nucleus and membrane-bound cell organelles.
