  Name of 100 living organisms in the world There are many living organisms in the world. They are Human, tiger, bear, lion, dog, cat, horse, pig, rat, garden lizards, house lizard, Snell, hippopotamus, mango tree, coconut tree, banyan tree, banana tree, mushrooms, polar bear, yak, cow, goat, sheep, wolf, jacket, fox, tortoise, cobra, anaconda, crocodile, pegion, peacock, hen, parrot, bacteria, algae, ant, spider etc. Basis characteristics of living organism Following  basic characteristics of living organisms  distinguish them from non-living. These are the basic  19 characters of living organisms 1. Individuality:  Every  organism  exists as a single unit and has its own individuality. It can't be separated into completely different components for its survival.  2. Form and size:  Every  organism  incorporates a definite form and size. A non-living object will have any form.  3. Chemical organization:   Organisms  a...

Class 6th science chapter 2 note Components of food In this chapter- What is nutrient?    Carbohydrates   Fats    Proteins    Vitamins     Minerals  Roughage and water Balanced diet  Deficiency disease What is nutrients? Every days is made up of one or more ingredients.  The ingredients are the edible part of plants or animals which contains some compounds which are needed by our body called nutrients.  The major nutrients of our food are carbohydrates, fats, proteins, vitamins and minerals.  Roughage and water are also needed by our body.  Not all the food materials that we eat have the same nutrients. Carbohydrates   There are many type of carbohydrate.  The main carbohydrates which are found in our food and in the form of starch and sugar.   It gives us energy to work so it is called energy giving food.  The food like rice, wheat, potato, sugar, sweet potato are rich in carbohydrates....

Class 6th science chapter 1 note Food- where does it come from?  In this chapter- Why do we need food? What is ingredient? Food materials and sources  Plant parts and animal products as food  What do animals eat? Detailed note- Why do we need food? All living beings need food and water.  It gives energy to work. It keeps us healthy. It helps us to grow. It gives us essential nutrients to fight against disease. What is ingredient? Ingredients are the components of our food.  Different food items and made with different kinds of ingredients.  For example, to make rice we need raw rice and water near raw rice and water at the ingredients of rice. Food materials and sources The main source of our food are plants and animals.  Some of our food such as different grains vegetables and fruits at come from plants. The food items like milk egg and made at home from animals. Plant parts and animal products as food Parts of a plant which does not cause any harmful...

Function of hormones of  adenohypophysis   Adenohypophysis is the real glandular part of the pituitary gland. The cells adenohypophysis secreted several hormones.  The hormones of adenohypophysis are 1. Somatotrophic hormone(STH): Growth hormone is secreted by the acidophill cells of the adenohypophysis.  It is polypeptide in nature consisting of large branches.  The molecular weight in human beings is 21500. The hormone regulates the growth of the body is thus it is necessarily concerned with the growth of skeleton, growth of muscle and growth of other organs.  Function - It stimulates the growth of skeleton in general by promoting ossification.  Hyper activity of gland in the young increases the growth of skeleton and this condition is known as gigantism.  Hypofunction of gland retrads skeletal growth and produce dwarfism.  The hormones promotes protein anabolism.  The hormone elevates the blood glucose level by stimulating glycog...

In this page- Adenohypophysis  i. Pars distalis ii. Pars tuberalis iii. Pars intermedia     Adenohypophysis- Adenohypophysis is developed from the oral ectoderm. It is divisible into 3 parts i. Pars distalis ii. Pars tuberalis iii. Pars intermedia Pars distalis, pars tuberalis, pars intermedia consists of the anterior lobe of pituitary gland. 1. Pars distalis The part of adenohypophysis is made up of parenchymal cell. It is of two types A. Chromophobes The important character of these cells are they apper in groups near the centre of cord. In ordinary preparation, the cell membrane are not distinguishable. Secretory granules are mostly absent. They do not secrete any hormone. They give rise to other types of cells. B. Chromophylls In chromophylls again two cells are found. They are a. Acidophills These are readily stained with acid dyes. It is of two types. i. Somatotroph or somatotrophic cells The round and ovoid in shaped cells are the secrerory cells. They are pre...

  How do we feel when we touch a human salivary glands? Human saliva is secreted by three major types salivary glands  which are 1.  Parotid glands 2.  Submandibular or submaxilary glands 3.  Sublingual glands Which are present in different parts of mouth along with these there are also some minor salivary glands present on our checks and lips also. When we touch a human salivary glands we feel wet as the secretion of this gland which is saliva contains 99.05% water and 0.05% solute.  Want to know why it feels watery when we touch a human salivary glands in details? then read below to get your answer clearly.  Salivary glands  Salivary gland  is an exocrine gland. It releases a  secretion of saliva  in oral cavity. It is important to clean mouth and keep moist the mouth and pharynx. when the food s entered into the mouth the tactile receptors sense it and promote  salivary glands . Even when we think about the food the  sa...

In this page- Neurohypophysis   Hormones of neurohypophysis     i. Vasopresin and its functions    ii. Oxytocin and its functions   Neurohypophysis Neurohypophysis develops from neural ectoderm. It is called posterior lobe. The cells of neurohypophysis are called pituicytes. These are fusiform cells. Yellow and brown pigments are present in these cells. They are called pituicytes of Bucy. Granules of pituicytes are composed to unsaturated neutral fat and such, they are easily stained with asmic acid. The hormone pass down along axon in the hypothalamus hypophysial tract into the posterior lobe of the hypophysis. The hormones are stored in the neurohypophysis . Hormones of neurohypophysis The hormones of the neurohypophysis are actually secreted by the nuclear of the hypothalamus. Neurohypophysis is the storage area for the release of these hormones. These are two very important hormones of the neurohypophysis . i. Vasopresin or anti-diuretic hor...
