Biology Class: Bacteria

What are the characteristics of Bacteria? (Select right one)

• Distinguishing circular DNA of nucleoid / Lack of membrane-bound organelles / Lack of organelle like chloroplasts and mitochondria

• Are eukaryotic (contain a nucleus)

  Majority have a mitochondria

  They all prefer aquatic environment over any

• They have no cytoplasm or cellular organelles

  Majority contain DNA or RNA, but none have both

  Are surrounded by a protective coat referred to as a capsid

• Are multicellular eukaryotes. They have organelles called chloroplasts and cell walls made of cellulose. Their cells have a nucleus and membrane-bound organelles.
