Example Question #4 : Cell Biology
The cell is the most basic unit of life in all known organisms. Integral to its function is its ability to maintain intracellular and extracellular boundaries. Maintaining these boundaries is the function of membranes.
Which of the following choices include cells that have both a cell wall and a membrane?
I. Bacterial cells
II. Fungal cells
III. Animal cells
II and III
I only
