As an environmental engineer, you will follow the scientific method and start your work by generating a hypothesis first.
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.
Include in your answer the lipid bilayer, structural components of cell membranes and those of cell walls, and discuss the selective permeability characteristic of membranes.
