Life Processes
जीवन प्रक्रियाएँ
In Class 10 Science, the chapter Life Processes explains the essential functions that keep organisms alive. It covers nutrition and how living beings obtain and use food, respiration for releasing energy, transportation of materials within plants and animals, and excretion for removing wastes. The chapter helps students compare these processes across different organisms and understand how body systems work together to maintain life.
1Nutrition
पोषण
In this Class 10 Science topic from the chapter Life Processes, students learn how organisms obtain and use food for energy, growth, repair, and maintenance. The topic introduces autotrophic nutrition in plants, including photosynthesis and the role of chlorophyll, sunlight, carbon dioxide, and water, as well as heterotrophic nutrition in animals. Students also study human nutrition through the digestive system, the functions of digestive organs and enzymes, absorption of nutrients in the small intestine, and the importance of a balanced diet.
13 questionsRespiration
श्वसन
In this Class 10 Science topic from the Life Processes chapter, students learn how organisms obtain and use energy through respiration. The topic explains the difference between breathing and cellular respiration, the role of glucose and oxygen, and how energy is released as ATP. It also covers aerobic and anaerobic respiration, the human respiratory system, gas exchange in the lungs, and the production of carbon dioxide, water, and energy during the process.
36 questionsTransportation
जीवों में परिवहन
In this Class 10 Science topic from the Life Processes chapter, students learn how materials move within plants and animals to support survival. The topic explains the human circulatory system, including the heart, blood, blood vessels, double circulation, and lymph, along with the transport of oxygen, nutrients, hormones, and wastes. It also covers transport in plants through xylem and phloem, and shows how transpiration helps in the movement of water and minerals from roots to leaves.
29 questionsExcretion
उत्सर्जन
In this Class 10 Science topic from the chapter Life Processes, students learn how organisms remove harmful metabolic wastes and maintain internal balance. The lesson focuses on the human excretory system, including the roles of the kidneys, ureters, urinary bladder and urethra. Students also study the structure of a nephron and understand how filtration, selective reabsorption and urine formation take place. The topic explains excretion in plants and connects waste removal with the proper functioning of the body.
