Bacteria are prokaryotic organisms that do not contain chlorophyll. They are unicellular and do not show true branching. They differ from eukaryotes in not having a nuclear membrane, a nucleolus, and cell organelles like mitochondria, golgi apparatus and endoplasmic reticulum. They have a single circular chromosome. For growth and multiplication of bacteria, they require nutrition …
