Diversity in Living Organisms Videos by Exam Fear:
- Classification helps us in exploring the diversity of life forms.
- The major characteristics considered for classifying all organisms into five major kingdoms are:
- Whether they are made of prokaryotic or eukaryotic cells.
- Whether the cells are living singly or organised into multi-cellular and thus complex organisms.
- Whether the cells have a cell-wall and whether they prepare their own food.
- All living organisms are divided on the above bases into five kingdoms, namely Monera, Protista, Fungi, Plantae and Animalia.
- The classification of life forms is related to their evolution.
- Plantae and Animalia are further divided into subdivisions on the basis of increasing complexity of body organisation.
- Plants are divided into five groups : Thallophytes, Bryophites, Pteridohytes, Gymnosperms and Angiosperms.
- Animals are divided into ten groups: Porifera, Coelentrata, Platyhelmenthis, Nematoda, Annelida, Arthropoda, Mollusca, Echinodermata, Protochordata and Vertebrata.
- The binomial nomeclature makes for a uniform way of identification of vast diversity of live around us.
- The binomial nomeclature is made up of two words - a generic name and a specific name.
