Question

Assertion :Growth in non-living objects is external as material is accumulated on the surface Reason: Growth in living organisms is internal as biomass is synthesized in the cell

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is true but Reason is False
• D. Reason is true but Assertion is False

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

• In a non-living organism, The process of growth is by the accumulation of materials on the surface.
• The living organism begins life as a single cell.
• Unicellular organisms may stay as one cell but they grow too.
• Multicellular organisms add more and more cells to form more tissues and organs as they grow. Growth and development of living organisms are not the same things.
• Hence, Growth in non-living objects is external as the material is accumulated on the surface and Growth in living organisms is internal as biomass is synthesized in the cell.
• So, the correct answer is ' Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
