Science (086) — AI-generated practice question

The student's argument is incorrect.

A seed in a dry jar is very much alive, even though it shows no visible movement. According to our understanding of life processes, visible movement is not the defining criterion of life. What is essential is molecular movement — molecules must be continually moved around to maintain and repair the organised living structures of the organism.

A seed carries out life processes at a very low rate — cellular maintenance continues at the molecular level. The moment conditions become favourable (water, warmth), it germinates, proving it was alive all along. Absence of visible activity does not mean absence of life.

• The examiner expects you to directly counter the argument using the textbook concept that molecular movement, not visible movement, is the true marker of life.
• Mention that life processes (nutrition, respiration, etc.) must continue even during apparent inactivity — the textbook explicitly states maintenance goes on "even when we are just asleep."
• The seed example is classic: low metabolic activity ≠ non-living. Germination is proof of life.
• Avoid writing too much — 3 marks = ~3 clear points, each worth 1 mark.
