Describe the cross - section side view of a Gram - negative cell . Clearly state where the following would be located or write the letters in order of appearance from the outside to the inside . If any of these structures are not present , make sure to leave them out . A ) peptidoglycan ; ( B ) periplasm ; ( C ) porin ; ( D ) LPS ; ( E ) teichoic acids ; ( F ) plasma membrane : ( G ) outer membrane : ( H ) nucleoid
Explain the importance of the Gram positve structure:- They contain a thick peptidoglycan layer and cytoplasmic lipid membrane.- These bacteria lack an outer membrane.- Have a lower lipid content and more teichoic acids.- They move around with the help of locomotion organs such as cilia and flagella.
