Which cellular component contributes to the protection, communication, and passage of substances into and out of the cell?
Correct answer
B
Rationale
The cell membrane is responsible for protecting the cell, facilitating communication with the external environment, and controlling the passage of substances into and out of the cell. It acts as a barrier, regulating the entry and exit of molecules to maintain the cell's internal environment. The nucleus, endoplasmic reticulum, and cytoplasm have their own distinct functions within the cell but do not primarily serve the purposes mentioned in the question.
