Answer 1

Clasification of bacterias based on the form of the cell wall

Circular

Rod-shaped

Curved

Other shapes

Clasification based on the composition of the cell wall

Gram positive: have a thick peptidoglycan layer and do not have an outer lipid membrane.

Gram negative: have a thin peptidoglycan layer and do not have an outer lipid membrane.

Gram-positive bact:eria are classified by the color they take on after applying a chemical process called a Gram stain. Gram-positive bacteria stain blue. Other bacteria stain red, they are gram negative.

They stain differently because their cell walls are different.
