The cel membrane and outer membrane are both important to consider in understandl The structure and function of a particular microbe, but internal structures alsoExplanation / Answer
VERRUCOMICROBIALES: have prosthecae and interior bound structrues, in addition to a clearly identifiable peptidoglycan cell wall.
DENIOCOCCI: contains carotenoids and flexirubins in their cell membranes.
MYCOPLASM: have increased amounts of sterols to help resist osmotic lysis, some also have yellow caretenoids to protect against damage from reactive oxygen species.
PLANCTOMYCETES: have cell membrane that investigate to form an internal membranous structure, they were thought to lack peptidoglycan until cryo-electron tomography was used to look for it.
FLEXIBACTERIA: lack lipid A and may be red or pink from carotenoids.
