Interactive Notes: Biological Classification Biological Classification Understanding the Diversity of Life The Need for Classification Since the dawn of civilization, humans have attempted to classify living organisms. Early classifications were instinctive, based on immediate needs for food, shelter, and clothing. Aristotle provided an early scientific basis, classifying plants into trees, shrubs, and herbs, and animals

Kingdom Monera -NCERT-NEET-Bacteria are the sole members of the Kingdom Monera. They are the most abundant micro-organisms. Bacteria occur almost everywhere. Hundreds of bacteria are present in a handful of soil. They also live in extreme habitats such as hot springs, deserts, snow and deep oceans where very few other life forms can survive. Many of them live in or on other organisms as parasites

Mycorrhiza and Plant Symbiosis Table Aspect Details Symbiotic Association Mycorrhiza is a symbiotic relationship between fungi and plant roots. Fungal Role in Mycorrhiza The fungal filaments either form a network around young roots or penetrate root cells, significantly increasing the surface area for absorbing water and minerals. Plant Benefits Plants receive minerals (like phosphorus) and

NEET-NCERT-In Linnaeus’ time a Two Kingdom system of classification with Plantae and Animalia kingdoms was developed that included all plants and animals respectively. 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 easilydone and was easy to understand, but, a large number of organisms did not fall into either category. Hence the two kingdom classification used for a long time was found inadequate. Besides, gross morphology a need was also felt for including other characteristics
