Diversity in Living Organisms

  1. 1. Diversity In Living Organisms Made By :Rishabh Anand Class : IX Sec : ‘C’ Roll No. : 28 School :KV No.2 AF Srinagar
  2. 2.  We classify organisms because of the following reasons It helps us to identify and communicate easy It helps us to study easier about them  There are millions of organisms (approx.. 1.5 million) in the world  To Understand and study all these organisms is impossible. If they are arranged into different groups based on their similarities in characteristics, then it is easier to study the group as a whole.
  3. 3.  These Biologists such as Ernst Haeckel (1894),Robert Whittaker (1959) and Carl Woese (1977) have tried to classify organisms into broad categories called Kingdoms.  Whittaker classify Organisms into five Kingdoms 1.Moners 2.Protista 3.Fungi 4.Plantae 5.Animalia  They classified organisms through their cell structure , mode and source of nutrition,etc.
  4. 4.  Woese introduced by dividing the Monera into           Archaebacteria and Eubacteria. Woese further classified by naming the sub groups at various levels. Given Below:Kingdom Phylum (for animals )/Division (for plants) Class Order Family Genus Species Thus, by separating organisms on the basic of hierarchy characteristics into smaller and smaller groups we arrive at basic classification. Which is a species. Whittaker divided species into five kingdoms.
  5. 5. 1.Monera 2.Protista 3.Fungi 4.Plantae 5.Animalia
  6. 6.  They do not have defined nucleus or organelles –     Prokaryotes. They are unicellular organisms. They show diversity based on many characteristics. Some have cell wall some do not have cell wall. They can be heterotrophic (they get food from outside the body) and autotrophic (they can synthesising their own food ).
  7. 7. Blue green algae
  8. 8.  They are Eukaryotic organelles.  They are unicellular organisms.  Some of them use Appendages – Hair like cilia or whip for moving around .  Their mode can be heterotrophic or autotrophic.
  9. 9.  They are Eukaryotes organelles.  They are heterotrophic organisms which use decaying organic material as food and are called as Saprophytes.  Many of them have the capacity to became multicellular organisms at certain stage of their life's.  They have cell wall made up of tough complex sugar called Chitin.  Some fungi live with permanent mutually dependent relationship with blue green algae and are called as Symbiotic . And the life process is called Lichens.
  10. 10.  These animals are multicellular organisms with cell     walls. These are eukaryotes organelles. They are autotrophic- use chlorophyll for photosynthesis. All plants lie in this Group. They are defined into subgroups.
  11. 11.  They are Multicellular organisms.  They are Eukaryotes organelles.  All animal lie in this group.  They do not have cell wall.  E.g.:-
  12. 12. Organisms Prokaryotes Eukaryotes Unicellular Unicellular Multicellular Monera Protista With cell-wall Without cell-wall Animalia Do not perform photosynthesis Fungi Able to perform photosynthesis Plantae
  13. 13. Plantae is divided into many parts:1.Thallophyta 2.Bryophyta 3.Pteridophyta 4.Gymnosperms 5.Angiosperms
  14. 14.  The plant that do not have well differentiated body design lie in this group.  This group is mainly found in aquatic .  This group is commonly called Algae.  These have naked Embryos and are called spores and are very inconspicuous and therefore called Cryptogamae or those with Hidden reproductive organs.
  15. 15.  This group is called Amphibians of the plant Kingdom.  This group is commonly differentiated to form stem and leaf-like structure.  This group do not have tissue for conduction of water and other substance from one part to another part of the body.  Their reproductive organs is hidden or Cryptogamae.
  16. 16.  This group is commonly differentiated to form stem, root and leaves and it has tissues for conduction of water and other substances from one part to another part.  Their reproductive organs is hidden or Cryptogamae.
  17. 17. And those animals who has well differentiated reproductive organs is called Phanerogams. And they are dived further into naked or enclosed in fruits.
  18. 18.  Gymnosperms is made up of two Greek words: Gymno –naked and sperms –seed.  This groups plants bear naked Seeds and they are perennial(living more than two or more years),evergreen and woody.
  19. 19.  Angiosperms is made up of two Greek words:      Angio – covered and sperma – seeds. This group seeds develop inside an organ which became as fruit & they are also called flowering plant. Plant embryos in seeds have structures called Cotyledons. Cotyledons are called ‘seed leaves’ because in many instances they emerge and became green when the seed germinates. Angiosperms are divided into two parts. If there is only one cotyledons present in it is called Monocotyledonous or monocots. If there is only two cotyledons presents in it called Dicots.
  20. 20. Monocots - Paphiopedilum Dicots - Ipomoea
  21. 21. Plants Do not have differentiated plant body Have differentiated plant body Thallophyta Without specialised vascular tissue With vascular tissue Bryophyta Do not produce Seed Pteridophyta Plantae Produce Seed -Phanerogams Bear naked seeds Gymnosperms Have seeds with two cotyledon Dicots Bear seeds inside fruits Angiosperms Have seeds with one cotyledon Monocots
  22. 22. Animalia is divided into many parts 1.Porifera 7.Mollusca 2.Coelenterata 8.Echinodermata 3.Platyhelminthes 9.Protochordata 4.Nematoda 10.Vertebrata 5.Annelida 6.Arthropoda
  23. 23.  Porifera means –Organisms with holes.  They are non motile – attached to some solid support .  They are commonly found in marine or water.  There are holes all over the body these led to canal system that helps in circuiting the water all over the body that helps in bringing oxygen and food to body.  These animals are covered with outside layer or skeleton.  There is minimal differentiated body design and division into tissue.
  24. 24.  This group animals live in water.  They show more body design than Porifera .  There is cavity in body.  There is two layers of skin :One is inside the body and second is outside the body.  Some animals of this group live in groups (colonies) while some live in single.  Some have solitary like spa (Hydra) live single.
  25. 25. Live in group Live in single
  26. 26.  Body design is more differentiation than Porifera and       coelenterate. The body is Bilaterally symmetrical –left and right halves of the body is same. There are three layers of cells in which tissues can be formed is called Triploblastic. They do not have true cavity or coelom in which well developed organs be accommodated. Their body is flattened. They are also called Flatworms. They are free living or parasitic.
  27. 27.  The body is bilaterally symmetrical & Triploblastic.  Their body is Cylindrical not flattened.  There are tissues but no real organs and they have cavity.  These worms causes some diseases like Elephantiasis causing intestines diseases.
  28. 28.  The body is bilaterally symmetrical & Triploblastic.  But they have true body cavity and this allows organs to be packed.  These animals are segmented – Segments lined up from head to tale.  These animals are mainly found in the Fresh water and marine water as well as land.
  29. 29.  Arthropod means Jointed legs.  This is the largest group of animal.  The body is bilaterally symmetrical & Triploblastic.  They have open circulatory system so that blood does not flow in well defined path.  This animal have cavity filled with blood.
  30. 30.  The body is bilaterally symmetrical.  Their cavity is reduced and there is little segmented.  They have open circulatory system and kidney for excretion.  This body has foots for moving around.
  31. 31.  Echinodermata is divided into two Greek words.  Echinos – Hedgehog & derma – Skin.  They have spiny skinned organisms.  They are free living Marine organisms.  They are triploblastic & they have cavity.  They have peculiar water driven tube system for moving around &they have calcium carbonate structures which they as Skelton.
  32. 32.  The body is bilaterally symmetrical Triploblastic &     have cavity. They have new feature of body design (i.e.) Notochord during some stage of life. Notochord is a long rod like support structures that runs along the back of the animal separating the nervous tissue form the gut &it provides a place for muscles to attach for ease of movement. They have proper protochordates during some stages of their life's . Mainly Protochordates are marine animal.
  33. 33. Balanoglossus
  34. 34.  They have true vertebral column and internal skeleton       allowing complete different movement. The body is bilaterally symmetrical Triploblastic & segmented. They have differentiated body design and tissues. Here all chordates have same features . They have notochord and a dorsal nerve cord. They are triploblastic & have paired gills pouches. They have coelomate. Vertebrata in divided into five parts.
  35. 35.  Pisces are fish & they are aquatic animals.  Their skin is covered with scale plates & they take dissolved oxygen from water by gills.  The body is streamlined have muscular tail for movement &their body is cold blooded &have only two chamber.  They lay eggs.  There are many type of fish like skeleton made fully made of cartilage such as sharks.
  36. 36.  They do not have scales but have mucus glands in the skin &they have three chambers heart.  They can take respiration through gills or lungs & they lay eggs.  We can find in water as well as water.
  37. 37.  These animals are cold blooded & have scales.  They breathe in lungs & most animal have four heart chambers .  They lay eggs made up of tough covering and do not need to lay eggs in water unlike amphibians.
  38. 38.  They are warm blooded animals and have a four chambered heart & lay eggs.  There is an outside covering of feathers and two forelimbs are modified for flight but they breath through lungs.  All Birds fall in this category.
  39. 39.  Mammalia are warm blooded animals & have four heart chambers.  They have mammary glands for the production of milk to nourish their young and their skins has hair with sweet and oil glands.  This animals produced their young ones like kangaroos give birth to very poorly developed young ones.

Animals Cellular level of organisation Tissues level of organisation Porifera No body cavity between epidermis & gartrodermis Pseudocoelom Colomate Nematoda Coelenterata, Platyhelminthes Mesodermal cells from a single cell during growth of the embryo Annelid, Mollusca, Arthropoda Coleom formed from pounches pinched off from the endoderm No notochord Echinodermata Notochord present Chordata
  41. 41. Notochord present in at least larval forms, but very rudimentary Notochord replaced by vertebral column in adults Protochordata Exoskeleton of scales, endoskel eton of bone/cartilage breathing through gills Gills in larva, lungs in most adults, slimy skin Exoskeleton of scales, layin g eggs outside water Pisces Amphibia Reptilia Vertebrata Exoskeleton of feathers, lay eggs outside water, fight possible Aves Exoskeleton of hair, external ears, mostly giving birth Mammalia
