carboxypeptidase
Fungal cells have cell walls composed of chitin, a polysaccharide similar in structure to cellulose.
The cell walls of bacteria, plants, and fungi are of varying composition. Bacterial cells are composed of __________.
peptidoglycan
cellulose
chitin
glycogen
carboxypeptidase
Bacterial cell walls are composed of peptidoglycan, a protein and sugar moiety.
The cell walls of bacteria, plants, and fungi are of varying composition. Plant cells are composed of __________.
cellulose
peptidoglycan
chitin
glycogen
carboxypeptidase
Plant cell walls are made of cellulose, a polysaccharide.
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 and II
I only
I and III
II and III
I, II, and III
Plants, bacteria, and fungi have both a membrane as well as a cell wall. On the other hand, animal cells have only a membrane.
