Compare the different types of fruiting bodies that found in fungi? |
| Answer» The fruiting bodies of fungi contain spores, which are dispersed for reproduction .Mushroom are a familiar example of a fruiting body .Their are formed from hyphae, the tiny threads that make up the bulk of most fungi. They can be:Boletes & polyporesBoletes are mushroom-like, but with pores under the cap. Polypores vary from flat to mushroom-like and also have pores.Stinkhorns, puffballs & birds nest fungiStinkhorns are smelly, puffballs are powdery and birds nest fungi are cup-like with "eggs" inside.Cup fungiThe fruiting bodies are typically shaped like shallow cups or saucersCoral & jelly fungiCoral fungi are coral-like in shape, while jelly fungi are jelly-like to the touch.Stereoid & paint (or skin) fungiStereoid fungi are mushroom-like to bracket-like, with a smooth underside. A paint (or skin) fungus looks like an extra skin growing on the surface of some wood.Flask fungiThese produce their fruiting bodies in small chambersTruffle-like fungiTruffle-like fruiting bodies are generally out of sight, underground.\xa0\xa0 | |

Gram negative and positive bacteria |
|
Answer» Gram negative Bacteria are the bacteria which do not stain by gram staining and gram positive are the bacteria which get stain The gram-positive bacteria retain the crystal violet colour and stains purple whereas the gram-negative bacteria lose crystal violet and stain red. Thus, the two types of bacteria are distinguished by gram staining.Gram-negative bacteria are more resistant against antibodies because their cell wall is impenetrable.Gram-positive and gram-negative bacteria are categorized on the basis of the ability to hold the gram stain. The gram-negative bacteria are stained by a counterstain such as safranin and they are destained because of the alcohol wash. Hence under a microscope, they are noticeably pink in colour. Gram-positive bacteria, on the other hand, retains the gram stain and show a visible violet colour upon the application of mordant(iodine) and ethanol(alcohol).Gram-positive bacteria have a cell wall composed of multiple layers of peptidoglycan that forms a rigid and thick structure. Its cell wall additionally has teichoic acids and phosphate. The teichoic acids present in the gram-positive bacteria are of two types – the lipoteichoic acid and the teichoic wall acid. The cell wall is known as murein. |

Expansion of virus |
| Answer» \tViruses did not find a place in classification since they are not truly ‘living’.\tThe viruses are non-cellular organisms that are characterised by having an inert crystalline structure outside the living cell.\tOnce they infect a cell they take over the machinery of the host cell to replicate themselves, killing the host.\tVirus means venom or poisonous fluid, this name was given by Pasteur. D.J. Ivanowsky (1892).\tM.W. Beijerinek (1898) demonstrated that the extract of the infected plants of tobacco could cause infection in healthy plants and called the fluid as Contagium vivum fluidum (infectious living fluid).\tW.M. Stanley (1935) showed that viruses could be crystallised and crystals consist largely of proteins.\tViruses are nucleoproteins containing a nucleic acid (RNA/DNA) may be single stranded or double stranded surrounded by a protein coat called capsid made up of smaller units called capsomeres which are arranged in helical forms. | |

5 difference between 5 kingdom classification and 2 kingdom classification |
| Answer» The two kingdom classification was proposed by Aristotle and carolus linnaeus the father of taxonomy in 1768 it was very difficult to draw a line between Kingdom plantae and kingdom animalia for there were some organisms who had characteristics of animal kingdom and kingdom plantae for example euglena organism which was heterotrophic but have the capacity to do photosynthesis for it contain chlorophyll and it also possessed a cell wall which Kingdom animalia did not Robert H whittaker and American taxonomist in the year 1969 proposed five kingdom classification that was Kingdom animalia Kingdom plantae Kingdom fungi Kingdom Protista and Kingdom Monera virus was not included this was an appropriate division of kingdoms and now they could easily be a line drawn between all the kingdom\'s @diti? | |

Which part of kidney filter the blood |
|
Answer» Thanks Nephrone a unit of kidney filters the blood The basic structural and functional unit of a kidney is the nephron. There are more than eight lakh nephrons in each human kidney. It is made up of renal corpuscles and kidney tubules (renal tubules). The nephrons are the main regulators of the entire waste removal process from the body’s blood. It separates the different components present in the blood in order to filter it. It removes the unwanted toxic substances and waste present in the blood and adds back to the blood required molecules. |

Which type of sub unit present in lysosomes |
| Answer» Lysosomes are membrane-bound vesicles that contain\xa0digestive enzymes, such as\xa0glycosidases,\xa0proteases\xa0and\xa0sulfatases. Lysosomal enzymes are synthesized in the\xa0endoplasmic reticulum\xa0(ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of\xa0mannose-6-phosphate\xa0label. There are two types of lysosomes; secretory lysosomes and conventional ones. Conventional lysosomes are involved in the dismantling and re-cycling of various substrates presented to them through endocytocis,\xa0phagocytosis\xa0and by autophagosomes. They are responsible for returning many amino acids to the system. | |
