- Question:- Formulate a hypothesis on how bacterial cells use their characteristics to take up hydrocarbons from oil spills. Specify the mode of transport through the cell membrane (active vs. passive/endocytosis vs. exocytosis) and support your claim with scientific reasoning. Describe how these bacterial cells would take up hydrocarbons if: - they only possessed a cell membrane and lacked the cell wall. - they possessed membrane-bound organelles such as vesicles.
