key features in a bacterial cell

A

bacteria cells are unique as they have no nucleus no membrane no mitochondria no chloroplasts or vacuoles their dna is found naked as a single large chromosomes and many small circular plasmids

extra pieces of circular dna called plasmids

17
Q

compare chemical structure of cell wall in plants fungal and bacterial cells

A

plant cells walls are made of cellulose whereas bacterial and fungal cells are made of different chemicals

18
Q

purpose of staining cells to examine using microscope

A

allows you to see the details of cells contents because usually they are transparent eg iodine is used to stain cell walls and methylene blue stains nuclues
