A myofibril is a bundle of contractile filaments (myofilaments), 1-2 μm in diameter, that are arranged in parallel groups in the cytoplasm of striated muscle cells.
Myofilaments are bands of proteins that compose the cytoskeleton of muscle cells.
The function of a myofibril in short is to shorten and to contract.

A long filamentous organelle with a banded appearance is a myofibril. A myofibril is a cylindrical structure that extends along the complete length of each muscle cell.
pagal i dont know
Yes, a myofibril has a banded appearance. The sarcomere is delimited by two dark bands which are called the Z-discs. The Z-discs have two lighter colored bands and two darker bands.
