AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Haemoglobin, present in red blood corpuscles, binds with oxygen in the lungs and carries it to all body cells/tissues for cellular respiration.
Source: Life Processes, Section 5.4.1
The examiner looks for two key points: (1) haemoglobin is found in RBCs, and (2) its function is to carry/transport oxygen to body cells. The passage states "Oxygen is carried by the red blood corpuscles" — mentioning haemoglobin's binding property with oxygen earns full credit. Do not confuse with plasma, which transports CO₂ and food.
