Class 11th Biology - Exemplar 20. Locomotion and Movement

Answer :

These names refer to the muscle cells or muscle fibres. They are lined by a plasma membrane, which is known as sarcolemma, which encloses the sarcoplasm. The sarcoplasmic reticulum refers to the endoplasmic reticulum of the muscle cells, which acts as a storehouse for calcium ions.
