                                       Kingdom  Fungi  Introduction - The Fungi are heterotrophic organisms, lacking the ability to produce their own food, as they are without chlorophyll. The term Fungi has been derived from the Latin word meaning -Mushrooms. They can be defined as chlorophyllous organisms with nucleated, somatic bodies and cell wall made of cellulose and chitin or both, and they reproduce sexually as well as asexually. The study of fungi is known as Mycology . Organisms of this group are parasites or saprophytes. It include about 1,00,000 species . They have thallus like structure,i.e., the body is not differentiated.  Habitat -  The fungi grow in multiple habitats. In fact, they grow in every available habitat where organic matter, living or dead is found. Most of them are terrestrial. Some fungi are aquatic. The aquatic fungi are considered to be primitive. Many fungi are found in drinking water. They contaminate both our food and water. They are present

                                    Structure Of Neuron All animals have a very important functional neural system in their body which is comprised of highly specialized cells called Neurons which can detect, receive and transmit different kinds of stimuli. Every neuron is made up of a cell body and cell process (Dendron and axon ).                                                    Cell Body or Cyton -   It contains uninucleated cytoplasm. Except for centriole, all cell organelles are found in the cytoplasm . The centriole is absent in the nerve cell thus cell division is absent . Nissl's granules - Endoplasmic Reticulum and ribosomes form granules like structures called Nissl's Granules. Cell Process -   Dendron - The fine branches like structure extend out from the neuron is called dendrites . Some receptors are also present on it which receive the stimuli and produce Centripetal Conduction. The number of dendrites on neurons may vary. Axon - It is th
