Question

2. Growth, we say, is a characteristic of a living being. But some non living things like
crystals also grow; can you differentiate between the two kinds of growth? (2 marks)​

Answer 1

• Living things grow by the division of cells. Unicellular organisms such as Amoebae grow by an increase in the size of the single cell that makes up the organism. Non-living things grow by the addition of material from outside. For example, a pile of sand will grow if more sand is added to it.
