In biology, taxonomy ... including Linnaeus's system of sexual classification for plants (Of course, Linnaeus's classification of animals was entitled "Systema Naturae" ("the System of Nature"), implying that he, at least, believed that it was more than an "artificial system"). Plant pathology is related to most of the old and new sciences like biology, physics, chemistry, physiology, mathematics, genetics, soil science, biochemistry, biotechnology etc. 2) Epidemic diseases: - These diseases occur incidentally and occasionally in a particular locality. A plant may be said to be diseased, when … It is also called as Algae-Fungi because most of the characteristics of them are similar to algae like Vaucheria. As they feed the dead organic matters, fungi recycle about 85 percent of the carbon from dead organic matter; likewise, fungi release the locked-up nutrients so that they can be used by other organisms. Molecular Biology, Genetic Engineering, Biochemistry, Horticulture, Tissue Culture, Soil Science, Forestry, Physics, Chemistry, Meteorology, Statistics and many other branches of applied science. To study biotic (living), mesobiotic and abiotic (non-living and environmental) causes of diseases or disorders 2. Plant disease - Plant disease - Symptoms: The variety of symptoms, the internal and external expressions of disease, that result from any disease form the symptom complex, which, together with the accompanying signs, makes up the syndrome of the disease. A disease can be caused due to a variety of reasons. The majority of the plant pathogenic species can be classified into four groups, although more exist. Fungi are also used as the biological pesticides to control plant diseases, weeds, and insect pests. Deciduous plants are seasonal plants which shed its leaves at the end of the growing season, either during the winter season in the temperate climate or during the dry season in the tropical climate. Viruses are non-cellular, microscopic infectious agents that can only replicate inside a host cell. All viruses that spread within their host tissues (systemically) can be transmitted by grafting branches or buds from diseased plants on healthy plants. Interviewmania is the world's largest collection of interview and aptitude questions and provides a comprehensive guide to students appearing for placements in India's most coveted companies. Most of the fungal and bacterial parasites produce many enzymes that degrade the plant materials in vivo. Plant diseases are known from times preceding the earliest writings. Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Plant pathology has the following major objectives. Interviewmania is the world's largest collection of interview and aptitude questions and provides a comprehensive guide to students appearing for placements in India's most coveted companies. PLANT DISEASES Plant disease is an impairment of normal state of a plant that interrupts or modifies its vital functions. On the basis of the organisation of the vegetative thallus, the morphology of reproductive structures, the way of spores production and particular life cycle involved the kingdom mycota is classified into following divisions..
