According to the , life processes are the basic functions performed by living organisms to maintain their lives on earth. These vital processes are essential for survival and maintenance, continuing even while an organism is asleep. The key processes covered in this chapter include: Nutrition: Obtaining energy from food. Respiration: Utilizing energy from food. Transportation: Moving materials within the body. Excretion: Removing waste materials.
Autotrophic organisms, such as green plants, can synthesize their own food from simple inorganic substances like carbon dioxide and water, using sunlight as an energy source. The chapter explains the process of in detail, providing the balanced chemical equation. The textbook highlights the role of chlorophyll and the significance of stomata for gas exchange, explaining how sunlight, carbon dioxide, water, and chlorophyll work together to produce glucose (C₆H₁₂O₆) and oxygen (O₂).
The role of Xylem/Phloem (plants) and the Heart/Blood Vessels (humans).

Clear, well-labeled diagrams help in visualizing processes like human digestion, heart structure, and plant anatomy.
Transports prepared food (sucrose) from leaves to other parts of the plant via an energy-dependent process called translocation. According to the , life processes are the
Driven by the circulatory system. The four-chambered human heart acts as a double pump, separating oxygenated and deoxygenated blood. Blood consists of plasma, red blood cells (carrying oxygen via hemoglobin), white blood cells (immunity), and platelets (clotting).
