Example Questions
Example Question #1 : Cell Structures
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
I, II, and III
I only
I and III
I and II
II and III
I and II
Plants, bacteria, and fungi have both a membrane as well as a cell wall. On the other hand, animal cells have only a membrane.
Example Question #2 : Cell Structures

carboxypeptidase
peptidoglycan
glycogen
cellulose
chitin
cellulose
Plant cell walls are made of cellulose, a polysaccharide.
Example Question #3 : Cell Structures
The cell walls of bacteria, plants, and fungi are of varying composition. Fungi cells are composed of __________.
chitin
carboxypeptidase
glycogen
peptidoglycan
cellulose
chitin
Fungal cells have cell walls composed of chitin, a polysaccharide similar in structure to cellulose.
