- Why do cyanobacteria possess heterocysts? View Available Hint(s) for Part A Heterocysts shield the organism's nitrogen fixation enzymes from oxygen.

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.
