Answer 1

Each difference: (0.5 mark)
$\begin{array}{cc}\text{Prokaryotic cell}& \text{Eukaryotic cell}\\ \text{Most prokaryotes}& \text{Most eukaryotes}\\ \text{are unicellular}& \text{are multicellular}\\ \text{Size of the cell is}& \text{Size of the cell is}\\ \text{generally small(0.5-5}\mu m).& \text{generally large(50-100}\mu m).\\ \text{Nuclear region is poorly defined}& \text{Nuclear region is well-defined}\\ \text{due to the absence of a nuclear}& \text{and is surrounded by a nuclear membrane,or true}\\ \text{membrane or cell lacks true nucleus.}& \text{nucleus bound by a nuclear membrane is present in the cell.}\\ \text{Mostly contains a single chromosome.}& \text{It contains more than one chromosome.}\\ \text{Nucleolus is absent}& \text{Nucleolus is present}\\ \text{Membrane-bound cell organelles such as plastids,}& \text{Cell organelles such as mitochondria, plastids,}\\ \text{mitochondria,endoplasmic reticulum,Golgi apparatus,}& \text{endoplasmic reticulum, Golgi apparatus,lysosomes etc.}\\ \text{etc.are absent}& \text{are present.}\\ \text{Cell division occurs through binary fission}& \text{Cell division occurs by mitosis.}\\ \text{Prokaryotic cells are found in}& \text{Eukaryotic cells are found in}\\ \text{bacteria and blue-green algae.}& \text{fungi,plants,and animal cells.}\end{array}$
