Question

Fill in the gaps in the following table illustrating the differences between prokaryotic and eukaryotic cells.

	Prokaryotic cell	Eukaryotic cell
$1 .$ Size	Generally small ( $1 - 10 μ m$ ) $1 μ m$ $= 10^{- 6} m$	Generally large ( $5 - 100 μ m$ ).
$2 .$ Nuclear region	_____	Well-defined and surrounded by a nuclear membrane.
$3 .$ Chromosome	Single	More than one chromosome
$4 .$ Cell organelles	Membrane-bound cell organelles are absent.	_____

Accepted Answer

Prokaryotic cell Eukaryotic cell

Size Generally small ( $1 - 10 μ m$ )
$1 μ m = 10^{- 6} m$ . Generally large ( $5 - 100 μ m$ ).

Nuclear region In some organisms like bacteria, the nuclear region of the cell maybe poorly defined due to the absence of a nuclear membrane. Such an undefined nuclear region containing only nucleic acids is called nucleoid. Well-defined and surrounded by a nuclear membrane.

Chromosome Single More than one chromosome.

Cell organelles Membrane-bound cell organelles are absent. Membrane-bound cell organelles [e.g., chloroplasts(exclusively present in plants, algae, etc.), Golgi bodies, mitochondria, etc.] are present.
