or own an. This system of classification was not accepted because it includes both prokaryotic & eukaryotic chlorophyllous and non chlorophyllous organisms together. Instead, gas vacuole may be present. They require not only understanding the statements but also the correct and accurate conceptual reasoning. Meiosis in the zygote resulting in haploid spores. Euglena is a connecting link between animals and plants. Slime moulds are of two types : acellular and cellular. All single-celled eukaryotes are placed under Protista, but the boundaries of this kingdom are not well defined. The two fusing gametes are haploid and may be isogamous or anisogamous. They appear yellow, green, brown, blue or red depending on the main pigments present in their cells. Therefore, fungi is separated from plants and placed in Kingdom Mycota. (c): Linnaeus, 1758 developed “Binomial system of nomenclature”, de Candolle gave the term taxonomy. it represents the inter-relationship among plants. The reserve food material is starch in fresh water forms and oil in marine forms. Which of the following characteristic(s) is/are used by Whittaker for the classification of organisms ? Parasitic yeast cause diseases in human beings (e.g., cryptococcosis, blastomycosis and torulosis). Fimbriae take part in attachment like holding the bacteria to solid surfaces. On this basis of vascular tissue, he classified plants into two groups –. Protozoa are divided into four major groups on the basis of locomotory organelles. : The cytoplasm is a complex aqueous fluid or semi fluid ground substance (matrix) consisting of carbohydrates, soluble proteins, enzymes, coenzymes, vitamins, lipids, mineral salts and nucleic acids. Mycoplasma agalactiae causes agalactia of sheep and goat. occurs by three types of non-motile mitospores, that is sporangiospores, chlamydospores and oidia. The spores are dispersed by air currents. The book contains, in all, 2000+ questions with 95% + explanations. Fungi possess true nucleus having definite nuclear envelope. . It includes bacteria, actinomycetes, mycoplasma and cyanobacteria. Do you understand the meaning of classification? . Mitochondria, plastids, golgi apparatus, lysosomes, endoplasmic reticulum, centrosome, etc. Linnaeus classified plant kingdom into 24 classes on the basis of only two characters-stamens and  style in his book ‘. Commonly known forms of basidiomycetes are mushrooms, bracket fungi or puffballs. The classification of Eichler is very little phylogenetic. By Suresh in BIOLOGY CHAPTERWISE QUESTIONS & ANSWERS on 01/03/2020. They move and capture their prey by putting out pseudopodia (false feet) as in Amoeba. The protein coat called a capsid made of small subunits called capsomeres, protects the nucleic acid. Artificial system of classification was adopted by. - They are cosmopolitan and saprophytic fungus, living on dead organic matter. Digestion in Paramecium is intracellular. : All bacterial cells are covered by a strong, rigid cell wall. In "Genera plantarum," Linnaeus gave the detailed description of plant kingdom. Hello neet biology chapter wise mcq based on A and R, match the following, not matching pairs, select correct or wrong statement ,diagram ,fact and definition, application. Under favourable conditions, yeast grow rapidly and form false mycelium or. In higher forms, growing areas are called meristems. . Laveran (1880) discovered that malaria is caused by a protozoan parasite, Plasmodium vivax. All the non-chordates, urochordates and cephalochordates are collectively called invertebrates. This was very appreciable because floral characters are more stable than vegetative characters. He gave the four kingdom system of classification. land, air and water. This component provides a sticky character to bacterial cell (NEET 2017) A. Sometimes, under unfavourable conditions, they produce spores. The reserve food material is oil and a polysaccharide-chrysolaminarin (or leucosin). The mycelium is branched and septate. In this classification, the plants belonging to the same group show many similarities, while in artificial classification, the plants belonging to the same group show only, one or two similar characters. They contain red pigment astaxanthin. Become our. Sexual spores are called ascospores which are produced endogenously in sac like asci (singular ascus). Some plasmids are integrating into the bacterial DNA chromosome called episomes. In plants, the symptoms can be mosaic formation, leaf rolling and curling, yellowing and vein clearing, dwarfing and stunted growth. plants with seeds. Classification basically is the arrangement of things in taxonomic groups in accordance to the observed similarities. Biological Classification Multiple Choice Questions (MCQs) and Answers for competitive exams. The cell walls of fungi are composed of chitin and cellulose. They grow in soil, on logs and tree stumps and in living plant bodies as parasites, e.g., rusts and smuts. The somatic phase is diploid and consists of a free living organic matter with multinucleated protoplasm called plasmodium. In Natural phylogenetic classification, both morphology and phylogeny are considered. - To evolve a truly natural or phylogenetic system which should indicate origin and evolution of the species. It is composed of polysaccharides and the nitrogenous substances (amino acids) are also present in addition. Fermentation of fruits and fruit juices by yeast cells makes their taste unpleasant. The RNA of the viroid was of low molecular weight. They play a great role in recycling nutrients like nitrogen,  phosphorous, iron and sulphur.
