Question
Is the growing of crystal of copper sulphate considered as a living character? Give reasons.
Solution
The growth of the crystal of copper sulfate is not a living character. This is because the increase in its size is due to the deposition of new material externally and not from within. This is known as extrinsic growth. In living organisms, growth occurs due to the formation of new cells and the building up of protoplasm within cells.
