Q 23: Plants and animals show difference in growth. Do you agree? Justify.
✅ Answer
Yes. In plants, growth continues throughout their lifespan. In animals, growth is only up to a certain age. Q 24: Growth is not a defining property of living organisms. Why?
✅ Answer
Basically, growth is the increase in mass & size. Thus non-living objects also grow by surface accumulation of material. So growth is not a defining property of living organisms. Q 25: In unicellular organisms, growth & reproduction are same. Evaluate.
✅ Answer
In unicellular organisms, growth & reproduction occurs by cell division. So both are same. Q 26: Reproduction is not a perfect defining property of living organisms. Give reason with examples.
✅ Answer
Many organisms do not reproduce. E.g. mules, worker bees, infertile human couples, etc. Hence, reproduction is not a perfect defining property of living organisms. Q 27: Metabolism is a defining feature of living organisms. Do you agree? Justify.
✅ Answer
Yes. Because all organisms exhibit metabolism without exception. Metabolism is absent in non-living things. Q 28: (a) What is meant by Consciousness?
