On the basis of mycelium, mode of spore formation and fruiting bodies from 4 divide kingdom into 4 classes and explain general characteristics |
|
Answer» plz mark as brainiestExplanation:Biological Classification Kingdom Fungi The fungi are filamentous; except yeast (unicellular). The body consists of long, slender thread-like structures; called hyphae. The network of hyphae is called mycelium. Some hyphae are continuous TUBES which are filled with multinucleated cytoplasm. Such hyphae are called coenocytic hyphae. The other type of hyphae has septae or cross-walls. The cell wall of fungi is composed of chitin and polysachharides. Most of the fungi are heterotrophic and are saprophytes. Some are parasites. Some of the fungi also live as symbionts. Some of the symbiont fungi live as lichens; in association with algae. Some of the symbiont fungi live as mycorrhiza; in association with roots of higher plants. Reproduction in Fungi: Reproduction by vegetative means takes place by FRAGMENTATION, fission and budding. Some fungi reproduce asexually by forming spores which are called conidia or sporangiospores or zoospores. Sexual reproduction is by oospores, ascospores and basidiospores. The spores are produced in distinct structures called fruiting bodies. The sexual cycle involves three steps which are as follows: Plasmogamy: This involves fusion of protoplasm between two motile or non-motile gametes. Karyogamy: This involves fusion of two nuclei. Formation of haploid spores: This happens because of meiosis in zygote. During sexual reproduction, two haploid hyphae of compatible mating types come together and fuse. In some fungi, the fusion of two haploid cells immediately results in a diploid cell (2n). In other fungi (ascomycetes and basidiomycetes), an intervening dikaryotic stage occurs. In this stage, two nuclei are present in each cell. This condition is called dikayron. The parental nuclei fuse at a later stage and the cells become diploid. Reduction division in the fruiting bodies leads to the formation of haploid spores. On the basis of morphology of mycelium, mode of spore formation and fruiting bodies; Kingdom Fungi is divided into following classes: Phycomycetes: The members of phycomycetes are found in aquatic habitats and on decaying wood in moist and damp places. They can also be found as obligate parasites on plants. Mycelium: Aseptate and coenocytic. Reproduction: Asexual reproduction is by zoospores (motile) or by aplanospores (non-motile). These spores are endogeneously produced in sporangium. Zygospores are formed by fusion of two gametes. The gametes can be similar (isogamous) or dissimilar (ANISOGAMOUS). Examples: Mucor, Rhizopus and Albugo (the parasitic fungi on mustard). Ascomycetes: They are commonly known as sac-fungi. They are unicellular or MULTICELLULAR. They are saprophytic, decomposers, parasitic or coprophilous. Those growing on dung are called coprophilous. Mycelium: Branched and septate. Reproduction: Asexual spores are exogenously produced on the special mycelium called conidiophores. Sexual spores are called ascospores. They are produced endogenously in sac like asci. These asci are arranged in various kinds of fruiting bodies called ascocarps. Examples: ASPERGILLUS, Claviceps, Neurospora, yeast, penicillium, morels, baffles, etc. Basidiomycetes: They grow in soil, on logs and tree stumps. Some of them also grow in living plant bodies as parasites. Mushrooms, bracket fungi or puffballs are the commonly known forms. Mycelium: Branched and septate. Reproduction: Asexual spores are usually absent. Vegetative reproduction by fragmentation is common. Sex organs are absent. But plasmogamy is brought about by fusion of two vegetative cells of different strains. The resultant structure is dikaryotic which finally forms the basidium. Karyogamy and meiosis are responsible for formation of four basidiospores in a basidium. The basiodio spores are exogenously produced. Basidia are arranged in fruiting bodies called basidiocarps. Examples: Agaricus (mushroom), Ustilago (smut) and Puccinia (rust). Deuteromycetes: They are usually known as imperfect fungi because only the asexual or vegetative phase of them is known. A large number of deuteromycetes are decomposers, while some members are parasites. Mycelium: Branched and septate. Examples: Alternaria, Colletotrichum and Trichoderma. |

Answer» no.10 - Cattle feed produced by the Milk UNIONS/ Federations is a balanced source of essential nutrients required for body maintenance, growth and milk production.It is manufactured using good quality GRAINS, oil cakes/ meals, bran, MOLASSES, com- mon salt, minerals and vitamins. It is comparatively cheaper and highly palatable to the animals.● Cattle feed contains protein, energy, minerals and vitamins required for the growth, maintenance and milk production of animals. It is advantageous to feed extra cattle feed to PREGNANT animals for proper development of foetus.● It increases reproductive efficiency, milk production as well as fat content of milk.● Growing animals should be fed 1 to 1.5 kg of compound cattle feed daily.● MILKING animals should be fed 2 kg of compound cattle feed for body maintenance and additional 400g to cows and 500 g to buffaloes for every litre of milk produced . |

Write Article on AHIMSA Silk 100 word |
|
Answer» Ahimsa silk is a METHOD of non-violent silk breeding and harvesting. Wild silk moths are bred, rather than the domestic variety. It allows the completion of the metamorphosis of the silkworm to its moth stage, whereas most silk harvesting requires the silkworms to be killed in their COCOON stage. No animals suffer or die for the silk to be produced, making it a favorable alternative to normal silk for those who do not believe in harming animals. The pupa is allowed to hatch and the leftover cocoon is then used to create silk.While the Bombyx mori (also called mulberry silkworm or mulberry silk moth) are the preferred species for creating ahimsa silk, there are a few other types of species that fall under the category of ahimsa silk, which is defined not necessarily by the species of the moth involved but by the methods for harvesting the cocoon. The other types of silkworm that are used for this PROCESS are a subspecies of the ailanthus silkmoth and several types of tussah or Tasar moths: the Chinese tussah moth, the Indian Tasar moth, and the muga moth.The subspecies of the ailanthus silkmoth, Samia cynthia ricini, eat the leaves of the castor bean or cassava leaves. It is also known as the eri silkmoth. Eri silk is made from the COCOONS of these particular insects and is also produced using less violent methods than the normal heat treating, but the quality of Eri silk is often SEEN as inferior to that of the silk created by the offspring of the Bombyx mori moth. |
