Basic life processes are : Nutrition, Respiration, Transportation, Excretion etc. Life Processes require energy which is provided by nutrition. Modes of Nutrition 1. Autotrophic :-Kind of nutrition in which organisms can synthesize their own food Eg. Green Plants 2. Heterotrophic:- Kind of nutrition of which organisms do not possess the ability to synthesize their own food. They depend on autotrophs for their food supply directly or indirectly. Eg. Animals, Fungi HUMAN DIGESTIVE SYSTEM: As shown in the flow chart, digestion begins from th mouth.In the mouth it is broken down by salivary amylase. The food moves to the stomach through the oesophagus which performs persistatic movement. Enzymes and various digestion juices from liver,gall bladder and pancreas act on the chunks from the stomach in the small intestine. In the large intestine , the remaining nutrients are absorbed and the leftover is removed from the body through the rectum and anus. Respiration It is a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances. (i) Gaseous exchange : Intake of oxygen from the atmosphere and release of carbondioxide. (ii) Breakdown of simple food in order to release energy inside the CellularRespiration Transportation 1. Human beings like other multicellular organism need regular supply of food, oxygen etc., This function is performed by circulatory system or Transport system. 2. The circulatory system in human beings consists of : 3. Double Circulation : Blood travels twice through the heart in one complete cycle of the body. 1. Pulmonary circulation : blood moves from the heart to the hugs and back the heart. 2. Systemic circulation :blood moves from the heart to rest of the body and back to the heart. 4. Lymph – a yellowish fluid that escapes from the blood capillaries into the intercellular spaces. Lymph flows from the tissues to the heart assisting in transportation and destroying germs. 5. Transportation in Plants : There are two main conducting tissues in a plant. (a) Xylem (b) Phloem. 6. Transpiration is the process by which plants lose water in the form of vapours. 7. Role of Transpiration 1. Absorption and upward movement of water and minerals by creating PULL. 2. Helps in temperature regulation in Plant. 8. Translocation : Transport of food from leaves (food factory) to different part of the plant is called Translocation. 9. Excretion in human beings : The process of the removal of the harmful metabolic wastes from the body is called excretion. Excretory system of human beings includes : 1. A pair of kidney 2. A Urinary Bladder 3. A pair of Ureter 4. A Urethera • Process of Excretion Renal artery bring in blood containing waste substances to the kidneys. Kidney filters blood. ******CBSE 10th Biology : NCERT Syllabus : Free Online Science Smart Videos in HINDI ***** CBSE Syllabus 10th Biology in Hindi (All Chapters) NCERT X Science : https://www.youtube.com/watch?v=YPNOO...
