A student observed that an alum crystal kept in a saturated solution grows bigger in size over time. Why is this growth NOT considered a characteristic of a living organism?
The growth happens from the outside by accumulating external layers
The crystal absorbs organic nutrients directly from the solution
The alum crystal cannot change its place on its own
The alum crystal produces smaller crystals around itself
Solution
Living growth occurs from within the body through cell division, whereas crystal growth is a non-living process of adding matter externally.
