Give a comparative account of the classes of kingdom fungi under the following mode of nutrition mode of reproduction

Class 11th Biology Chapter 2 Biological Classifications NCERT Solution is given below. Question 1: Discuss how classification systems have undergone several changes over a period of time? Answer: The classification systems have undergone several changes with time. The first attempt of classification was made by Aristotle. He classified plants as herbs, shrubs, and trees. Animals, on the other hand, were classified on the basis of presence or absence of red blood cells. This system of classification failed to classify all the known organisms. Therefore, Linnaeus gave a two kingdom system of classification. It consists of kingdom Plantae and kingdom Animalia. However, this system did not differentiate between unicellular and multicellular organisms and between eukaryotes and prokaryotes. Therefore, there were large numbers of organisms that could not be classified under the two kingdoms. To solve these problems, a five kingdom system of classification was proposed by R.H Whittaker in 1969. On the basis of characteristics, such as cell structure, mode of nutrition, presence of cell wall, etc., five kingdoms, Monera, Protista, Fungi, Plantae, and Animalia were formed. Question 2:: State two economically important uses of: Heterotrophic bacteria Archaebacteria Answer: (a) Heterotrophic bacteria They act as decomposers and help in the formation of humus. They help in the production of curd from milk. Many antibiotics are obtained from some species of bacteria. Many soil bacteria...

Apart from this, we will also be sharing solved practice questions and answers, we will provide a list of the topics which are covered in the chapter, and give some quick preparation tips for the students of CBSE Class 11 on how to prepare for their Biology exam appropriately. 1. Discuss how classification systems have undergone several changes over some time? Ans: Biological categorization is the scientific method of grouping organisms into hierarchical groups and subgroups based on their similarities and differences. Scientists have developed various classification systems, which have undergone several revisions over time. Previously, Aristotle developed an artificial classification system that classified animals and plants according to their habitat. Aquatic (fish, whales), terrestrial (reptiles, cattle), and aerial (birds) are examples (e.g., bat, birds). Morphology, anatomy, physiology, reproduction, ontogeny, cytochemistry, and other factors were used to classify organisms back then. Following that, creatures were categorized using a phylogenetic framework based on evolutionary links. It uses cytotaxonomy, chemotaxonomy, numerical taxonomy, and cladistic taxonomy to classify organisms. 2. State two economical...

(a) Mode of nutrition • Phycomycetes are obligate parasites or saprophytes. • Ascomycetes are saprophytes or parasites or coprophilous. • Basidiomycetes are saprophytes or parasites. • Deuteromycetes are manly saprophytes, some are parasites. (b) Mode of reproduction • In phycomycetes, asexual reproduction is by zoospores (motile) or by aplanospores. • In ascomycetes, asexual spores (conidia) and sexual spores (ascospores) are produced. • In basidiomycetes, vegetative reproduction takes place by fragmentation. Plsamogamy is also seen. • In deuteromycetes, only vegetative reproduction is seen.

A few letter word diversity is itself a huge variation of a living creature. Have you ever thought of the life form that surrounds us? This is the beauty of nature. In this chapter we will focussed an the R.H. Whittaker biological classification of living organisms. He classified it into 5 kingdoms monera, protista, fungi, plantae and animalia. Here some are microscopic and some are huge but all are living creatures. Whereas no place in biological classification for viruses. What does this mean do viruses non living. You have heard of different viral diseases that mean they have a tendency to multiply with living cells. This is because viruses when outside the host they are non living but when comes in contact with the host body it becomes living. This is a peculiar feature of the virus. The classification systems have undergone several changes with time. The first attempt of classification was made by Aristotle. He classified plants as herbs, shrubs, and trees. Animals, on the other hand, were classified on the basis of presence or absence of red blood cells. This system of classification failed to classify all the known organisms.
