AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.

Source: Chapter 5, Section 5.1
The textbook gives a direct definition: "The processes which together perform this maintenance job are life processes." Examiners expect you to mention that these are maintenance functions essential for sustaining life, ideally with 1–2 examples (nutrition, respiration, excretion). Do not write a long paragraph — one clear sentence is enough for 1 mark.
