The Waxy Polymer on the Leaves of Vascular Plants That

Question

The waxy polymer on the leaves of vascular plants that protects them from pathogens is called
A)lignin
B)cutin
C)chitin
D)cellulose
E)sporopollenin

Accepted Answer

Cutin is a waxy polymer that is present on the aerial parts of vascular plants, mainly leaves and stems, and helps to prevent water loss and protect against pathogens. Lignin is a complex polymer that provides structural support to the plant cell walls. Chitin is a polymer that is found in the exoskeletons of arthropods and the cell walls of some fungi. Cellulose is a complex carbohydrate that makes up the cell walls of plants. Sporopollenin is a tough polymer found in the walls of spores and pollen grains.
