Life Processes Class 10 NCERT Solutions: The chapter explains various life processes that are required by organisms for the maintenance and proper functioning of the body. These processes form a basis of energy requirements. At first, the Science Chapter 6 Life Processes discusses Nutrition and various modes of nutrition in both plants and human beings. Nutrition can be defined as taking in food and utilizing it for energy requirements. There are two modes of nutrition in plants that are taught here are autotrophic nutrition and heterotrophic nutrition. Nutrition in human beings follows a series of sequential steps for the right mechanism of energy requirements.
Secondly, Science Chapter 6 Life Processes describes respiration, types, steps and breathing mechanism. Respiration is the oxidation reaction and mechanism of energy production aided by the intake of oxygen and the release of carbon dioxide. There are two types of respiration - Aerobic respiration and Anaerobic respiration. These can be differentiated on the basis of the presence and absence of oxygen. The breathing mechanism includes the process of inhalation and exhalation. In the case of plants, respiration happens through stomata, lenticels and root surface.
Science Chapter 6 Life Processes then explains the transportation in both Human Beings and Plants. The circulatory system of human beings includes - heart, arteries and veins, blood and lymph, whereas the transportation in plants is carried out with the help of a conducting pathway that includes the xylem and phloem.
The chapter further discusses the Excretory system in both human beings and plants. Excretion is defined as the removal of harmful waste from the body. The excretory system of human beings includes - kidneys, ureters, urinary bladder and urethra. The urine formation comprises three steps: glomerular filtration, tubular reabsorption, and secretion. The excretion in plants takes place via stomata, transpiration, raisins and gums.
