Chlorophycae / Phyaecophyeae / Rhodophycae

                          CHLOROPHYCEAE The members of chlorophyceae are commonly called green algae. ✓ discoid , plate like, reticulate Cup shaped in different species. ✓ storage body is called pyrenoids located in the chloroplast. Pyranoids contain protein besides starch. ✓ inner layer of cellulose and outer layer of pectose.                     PHYAECOPHYEAE   The members of phyaecophyeae are Blue Algae are found primarily in Marine habitats. • chlorophyll A • Xanthophyll pigment , Fucoxanthin. • form an Laminarin or Mannitol.  • Gelatinous coating of Algin.  • Hold fast and haas a Stalk the stipe and leaf like photosynthesic organ fronds. • Asexual reproduction in Most brown algae is by bioflagellated zoospores.  • Porioform ( Pear - Shaped )  • Ectocarpus , Dictyota , Laminaria, Saragassum & Fuccus.                         RHODOPHYCAE    • The members of rhodophycae are commonly called red Algae.  • because of predominace of the red pigment, r – phycoerythrin in the body.

Join Our Telegram Group:- GroveStudies   VIRUS ,VIROIDS PRIONS AND LICHENS In the five kingdom classification of whittaker there is known as mention of lichen and some a cellular organisms virus,viroids and prions. The virus are non cellular organisms that are characterized by having an in insert crystalline structure outside the living cell. The name virus that means venom or poisonous fluid was given by of the the Dimitri Ivanocosky 1892 recognise certain microbes as casual organisms of the the mosaic disease of tobacco. These were found to be smaller than bacteria because they are passed through bacteria proof filter. M.W. Beijerinek 1898 demonstrated that the the extract of the infected plants of tobacco could cause infection in healthy plants and called the fluids of contagium vivum fluidum (infectious living fluids).  W.M. Stanley 1935 show that virus could be crystalline and crystals consists lajari of proteins. • virus are obligate parasite. • viruses are contains genetic mate

Kingdom Monera / Archaebacteria / Eubacteria

Telegram :-  GroveStudies ©™✓                   KINGDOM MONERA Bacteria are the sole member of Kingdom Monera. Bacteria are grouped under four categories based on their save the spherical based on rod shaped Baccilus (Bacilli) , coma saved vibranium (vibrio) and the spiral Spirillum (Spirilia). Through the bacterial structure is very simple they are very complex in behaviour. * Bacteria show the most extensive metabolic diversity. ARCHAEBACTERIA These bacteria are special since they live in habitats such as extreme salty areas halophiles, hot springs ( thermoacidophiles). Archaebacteria differs from other bacteria in having a different from cell wall structure and this feature is responsible for their survival in extreme conditions. Methane gents are present in the gut of several ruminant animals such as cow and buffalo and they are responsible for the production of methane biogas from the dung of these animals. EUBACTERIA Eubacteria or "true bacteria". * Cyanobacteria (also
