Swallowtail

This table format is a very useful way to summarise key pieces of information such as these on organelle structure and function. Questions are often formatted so answers have to be filled into a table, so it is helpful to revise in this way. Tables can usefully be cut up for quick mix and match exercises. A helpful summary is included comparing prokaryotic and eukaryotic cells.
