Final answer:
Skeletal muscle cells have more than one nucleus.
Step-by-step explanation:
True. Skeletal muscle cells are multinucleate, meaning they have more than one nucleus. Unlike cardiac and smooth muscle cells, which have a single nucleus, skeletal muscle cells contain many nuclei. During development, smaller cells called myoblasts fuse together to form a mature muscle fiber, with each fused cell retaining its own nucleus. This allows for the production of a large amount of proteins and enzymes needed for muscle function.
