Life Processes Class 10 all Definition
All our Dear CBSE Champs, Here we Net Ex. have included Life Processes Class 10 all Definition. All the given definition are important for this year board exam.
- Life processes: Life processes can be termed as organisms which are capable of breathing, respiration, blood circulation, excretion and those organisms which can reproduce are called living organisms and all these processes are called as life processes.
- Nutrition: It can be defined as all vitamins, salts, ions, amino acid, protein, lipids fatty acid required to meet body’s daily requirement are intake by the living organisms to perform the work are called as nutrient and process of getting nutrients to carry out work called as nutrition.
- Autotrophic nutrition: The organisms which can prepare their own food are called autotrophs and those organisms getting nutrition by their own the process is referred to as autotrophic nutrition. Autotrophic nutrition is the process by which in presence of sunlight plants can prepare their own food that is glucose.
- Heterotrophic nutrition: The organisms which cannot prepare their own food are called as heterotrophs and such organisms not preparing their own food so they depend on others are called heterotrophic organisms and their nutrition termed as heterotrophic nutrition.
- Nutrition in human beings: The nutrition in human being is defined as the heterotrophic nutrition, they cannot prepare their own food but they can digest all the food for example they can degrade starch into amylose and amylopectin.
- Respiration: Respiration can be defined as the process of inhalation of oxygen and exhalation of carbon dioxide, the exchange of air occurs in diaphragm whereas all the processes of respiration occurs in lungs which is the respiratory organ.
- Aerobic respiration:Aerobic respiration can be termed as the process which occurs in presence of oxygen which starts with glucose and the end product is carbon dioxide and water. The process of aerobic respiration yields 32 ATP molecules.
- Anaerobic respiration: Anaerobic respiration can be defined as the process which will occur in absence of oxygen which usually start with glucose and its end product is ethanol. The process of Anaerobic respiration yields only two ATP molecules.
- Heart: Heart is one of the major circulating organ in body, in humans it is made up of auricles and ventricles. The number of auricles and ventricle may vary as per the species. The humans have 4 chambered heart in which two are auricles and two are ventricles.
- Xylem: It is the part of transport system in plants which is usually responsible for transportation of water. It is made up of tracheid and vessels. Xylem is also called as water conducting tissue. It is present in case of all plants. It transports the water to each and every part of plant.
- Phloem: It is the part of plant which is responsible for food and nutrients transportation. It does not involve in water conduction, it transports the food to each and every part of the plant therefore it is also called as food and nutrient conducting tissue.
- Nephron: It is one of the important cell which is present in kidney, it is structural and functional unit of kidney. In one kidney billions of nephrons are present. These nephrons are involved in filtration of water and salts and excretion of urine through the body.
- Excretory system: It is present in all the living organisms which is made up of different parts such as kidney, ureter, urinary bladder, urethra etc. It is responsible for excretion of all the waste product and maintaining the body’s homogeneous temperature and environment.
- Lymph: It is one of the fluid formed in the body which is majorly responsible for transportation in animals and humans. Lymph is formed from blood cells, plasma and various protein which are released from the small pores of capillary. It has same properties as that of plasma.
- Blood pressure: Blood pressure can be defined as the pressure exerted or released by the blood against the vessel wall is called as blood pressure. The normal range of blood pressure 120/80. The 120 is diastolic pressure whereas 80 is systolic pressure.
