Bio-Diversity
- 1. BIODIVERSITY
- 2. CONTENT •Define environment of earth •Types of things •Characteristics of living •Biodiversity •Why Biodiversity •Taxonomic system •Kingdom •Factors of classification
- 3. DEFINE ENVIRONMENT OF EARTH
- 7. WHERE IS THE BASIC UNIT OF LIFE?
- 8. MORE CHARACTERISTIC •LIVING THINGS ARE MADE OF CELLS. •LIVING THINGS ADAPT TO THEIR ENVIRONMENT.
- 9. BIODIVERSITY • EARTH IS OCCUPIED BY DIVERSE KINDS OF LIVING ORGANISMS • THEY LIVE IN VARIOUS ENVIRONMENTS. • THE WORLD IS ESTIMATED TO HAVE 5 TO 30 MILLION SPECIES OF LIVING ORGANISMS. • THUS THE EXISTENCE OF DIFFERENT FORMS OF A SPECIES OR GENUS AND DIVERSE ADAPTATIONS FOR, VARIED SURROUNDINGS ARE REFERRED TO AS “BIODIVERSITY”.
- 12. TAXONOMIC SYSTEMS •First introduced by Aristotle (384-322 BC). •He is considered as the Father Of Biological Classification.
- 14. TAXONOMIC SYSTEMS •Carl Linnaeus (1707 - 1778) the father of taxonomy. •Binomial nomenclature for all species of animals and plants. •Binomial nomenclature is a formal system of naming species of living things • The highest rank was given the name "kingdom" •Followed by four other main or principal ranks: the class, order, genus and species. •Later two further main ranks were introduced, making the sequence kingdom, phylum or division, class, order, family, genus and species.
- 15. The five-kingdom system, proposed in 1969 by Whittaker
- 16. FACTORS OF CLASSIFICATION •Structure of cells - {prokaryotic or eukaryotic } •Structure of organism - {unicellular or multicellular} •Mode of nutrition - photosynthesis in green plants, absorption in fungi and ingestion in animals.

Hinweis der Redaktion
- He emphasized that animals can be classified according to their way of living, actions, habits and body parts. The term taxonomy is a Greek word. Its components are taxis and nomos. While taxis means arrangement, nomos means law. Thus taxonomy is defined as the “theory and practice of classifying organisms”
- He used simple morphological characters to classify plants into trees, shrubs and herbs. He also divided animals into two groups, those which had red blood and those that did not.
- This system was used till very recently. This system did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organisms and photosynthetic (green algae) and non-photosynthetic (fungi) organisms. Classification of organisms into plants and animals was easily done and was easy to understand, inspite, a large number of organisms did not fall into either category.
- In the Whittaker system, Plantae included some algae. In other systems (e.g., Margulis system), Plantae included just the land plants (Embryophyta).
- Monera into the Eubacteria and Archeobacteria.
