NCERT Exemplar Class 10 Science Chapter 6 – Life Processes
The NCERT Exemplar Class 10 Science Solutions for Chapter 6 – Life Processes provide students with a detailed understanding of the basic functions that sustain life in living organisms. This chapter focuses on nutrition, respiration, transportation, and excretion—four essential processes that keep organisms alive. With the support of NCERT Solutions for Class 10 Science, students can clearly understand these biological mechanisms and their significance. The chapter begins with nutrition, explaining how autotrophs like plants prepare food through photosynthesis and how heterotrophs, such as humans and animals, depend on external sources. The differences between autotrophic and heterotrophic nutrition are highlighted, along with subtypes like saprophytic and parasitic nutrition. The importance of enzymes and digestive systems in humans is also discussed. Next, the chapter deals with respiration, the process of releasing energy from food. Students learn about aerobic and anaerobic respiration, the role of mitochondria, and how different organisms adapt to their environments through varied respiratory mechanisms. The chapter also explains how energy is stored in the form of ATP, which fuels cellular activities.
The section on transportation describes how plants and animals circulate essential materials. In humans, the circulatory system is explained in detail, covering the structure of the heart, blood vessels, and the role of hemoglobin. Students also explore the transport of water and minerals in plants through xylem and the movement of food via phloem, using the process of translocation. Excretion, another vital life process, is also explained. Students study how waste materials are removed from the body through the human excretory system, involving kidneys, ureters, bladder, and urethra. In plants, waste removal is discussed through diffusion and secretion. By solving NCERT Exemplar Class 10 Science exercises, learners can strengthen their understanding of these processes with application-based and higher-order thinking questions. Through NCERT Solutions for Class 10 Science Chapter 6, students gain conceptual clarity and can relate life processes to real-world examples, such as the role of respiration in exercise, the significance of blood donation, or the use of dialysis in kidney failure. This chapter not only prepares learners for exams but also helps them appreciate how living systems function in harmony.
