Myofibrils

Explanation:
Detailed explanation-1: -The striated appearance of skeletal muscle tissue is a result of repeating bands of the proteins actin and myosin that are present along the length of myofibrils. Dark A bands and light I bands repeat along myofibrils, and the alignment of myofibrils in the cell causes the entire cell to appear striated or banded.
Detailed explanation-2: -Skeletal muscle fibre cells are long and cylindrical with light and dark bands which gives a striated appearance.
Detailed explanation-3: -Myofibrils are composed of overlapping thick and thin myofilaments organized into distinct, repeating units called sarcomeres.
