Quizplus · Accepted Answer

Cell membranes are crucial for separating the cell from its external environment, allowing for the regulation of substances entering and exiting the cell, thus maintaining homeostasis. They are found in both plant and animal cells, primarily consist of lipids (not sugars), and are selectively permeable to allow transport into and out of the cell.
