Prokaryote: Bacteria

When drawing prokaryotic cells, the following should be included:

• The genophore (bacterial chromosome) should be drawn as a loop (prokaryotic DNA is circular)

• Pili and flagella should project from the cell wall (which is composed of peptidoglycan in bacteria)

• Ribosomes should be drawn as filled in dots (not as empty circles) and labelled as 70S in size

• A flagellum should be thicker than pili and significantly longer in length

• The shape should be appropriate to the type of bacteria (hint: bacillus are rod-shaped)
  

Eukaryote: Animal Cell

When drawing animal cells, the following should be included:

• The nucleus should be a double membrane structure with pores (any chromosomes should be linear)

• The ER network should be shown as connected membranes, but golgi membranes should be unconnected

• Ribosomes should be drawn as filled in dots (not as empty circles) and labelled as 80S in size

• Mitochondria should be sausage-shaped and the inner membrane highly folded (into cristae)

• Peroxisomes, lysosomes and secretory vesicles should all look the same (except for the labelling)
