Multiple Choice
In plant tissue, what are plant cell walls mostly made of?
A
Chitin
B
Cellulose
C
Peptidoglycan
D
Phospholipid bilayer
Verified step by step guidance1
Understand that plant cell walls provide structural support and protection to plant cells.
Recall that the main component of plant cell walls is a polysaccharide that forms strong fibers.
Identify that cellulose is a polysaccharide made of glucose units linked together, forming microfibrils that give rigidity to the cell wall.
Recognize that chitin is found in fungal cell walls, peptidoglycan in bacterial cell walls, and phospholipid bilayers make up cell membranes, not cell walls.
Conclude that plant cell walls are mostly made of cellulose.
