I believe the last option is the correct one for the illustration of the single celled organism provides and the environment that it is found living in.
<span>A cell can only grow so large in size because its
ability to exchange materials is affected by a growing surface-to-volume ratio.
Nature designed cells to be small in size because of the network of membranes
passing through it. If cells grow any bigger, membranes in it will not be able
to pass through its different parts and perform their purpose.
A cell is a network composed of many organelles (e.g. mitochondria, nucleus),
that communicate and work together to provide bodily functions. The cell is
small so that communication between organelles will be faster and much easier. When
cells are small they can be easily repaired when damaged and replicated when
needed.</span>
