Biology / Diversity in living organisms

Biology / Diversity in living organisms

The biological world is enormously diverse. There has to be an approach that enables us to get an idea of a group of organisms by studying a particular type. Living beings are classified as plants and animals.
Classification - the process of grouping similar things into groups or categories on the basis of similarities and differences.
Learn about Hierarchy of categories/groups - kingdom, phylum, class, order, family, genus, species and binomial nomenclature.
Five-kingdom classification by R.H.Whittaker :
•1. Kingdom Monera
• 2. Kingdom Protista
• 3. Kingdom Fungi
• 4. Kingdom Plantae
• 5. Kingdom Animalia
Major groups of plants -
i. Thallophyta (thallus = undifferentiated; phyta = plant)
ii. Bryophyta (Bryo = moss; phyta = plant)
iii. Pteridophyta (first land plants with vascular bundles)
iv.Gymnosperms (Gymnos = naked; sperms = seed)
v. Angiosperms (angio = enclosed ; sperma = seed) Angiosperms are divided into monocot and dicot
Classification of Animal Kingdom in order of their increasing complexity:
• It is classified as phyllum Porifera(porus = pore, ferre = to bear, porous animals = the sponges)
• Phyllum cinadaria (knide = nettle or stoing cell)
• Phylum Platyhelminthes (platys = flat, helminthes = worms)
• Phylum Nematoda(nema = thread, helmin = worm)
• Phylum Annelida( annulus = ring, eidos = form)
• Phylum Arthropoda (arthon = joint, podoa = foot)
• Phylum Mollusca(molluscus = soft)
• Phylum Echinodermata( echinus + spine, derma = covering/skin)
• Phylum Protochordata(protos = first, chordata = notochord), Phylum vertebrata( animals with backbone)
classification of vertebrates :
1. Class Pisces(fishes)
2. Class Amphibia(amphi = both
bios = (life)
3.Class Reptilia(reptare = to creep)
4.ClassAves(avis = bird)
5.Class Mammalia(mamma = breast)
