Class 10 Science Life Processes explains the fundamental activities essential for the survival of living organisms. These include nutrition, respiration, transportation, and excretion. The chapter begins with nutrition, describing autotrophic and heterotrophic modes, photosynthesis in plants, and digestive processes in humans. It then covers respiration, highlighting aerobic and anaerobic pathways, along with the role of mitochondria in energy release.
The topic of transportation explains the circulation of blood in humans, structure and function of the heart, and transport of water and minerals in plants through xylem and phloem. Excretion details the removal of waste products, focusing on the human excretory system and plant excretory methods. By learning this chapter, students understand how living beings maintain vital processes for survival and continuity of life. It also builds a foundation for advanced topics in biology, ensuring conceptual clarity for board exams and competitive tests.
