A group of structurally similar cells with highly related functions is called a [a].

Examine the muscle tissue specimen. Identify the muscle tissue. [a] The striations are formed by [b] bands and myosin bands.

[a] structures share a common ancestor or developmental origin but they now differ in structure and function, such as forelimbs of man and bat.
