Final answer:
The statement about the cuticle being a protective, nonliving cover is true.
Step-by-step explanation:
The statement 'The cuticle is a nonliving cover that serves to both support and protect the animal' is true. The cuticle serves an important protective and supportive role in various organisms. In arthropods, like insects and crustaceans, the cuticle forms an exoskeleton, which is comprised of layers including the epicuticle and the procuticle, which contains chitin and protein. This structure offers protection, prevents dehydration, and allows for flexibility and mobility. During the molting process, arthropods shed their exoskeleton to allow for growth, highlighting that it does not grow with the organism throughout its life.
In plants, the cuticle is a waxy layer that covers the aerial parts such as leaves and stems, reducing water loss and providing protection against environmental stress. This cuticle also plays a crucial role in controlling gas exchange with the environment, with specialized structures such as stomata assisting in this process.
Additionally, nematodes are encased in a cuticle that acts as a flexible but tough exoskeleton, offering support and protection, which must be shed for growth. The function of the cuticle, therefore, spans across different kingdoms, demonstrating its crucial role in survival and adaptation.
