Sarcoplasmic reticulum cells are those cells that contain:
Correct answer: C. RER less
- A. SER less
- B. RER more
- C. RER less
- D. Cytoplasm is more
Explanation
The sarcoplasmic reticulum (SR) is a specialized form of smooth endoplasmic reticulum found in muscle cells, primarily responsible for regulating calcium ions during muscle contraction. The correct answer is that sarcoplasmic reticulum cells contain less rough endoplasmic reticulum (RER) compared to their smooth endoplasmic reticulum (SER). The other options are incorrect as they either misinterpret the relationship between RER and SER in muscle cells or do not focus on the defining characteristics of the sarcoplasmic reticulum.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
