Question

question 2 the cell membrane (plasma membrane) is described as a highly - selective barrier. this structure plays an important role in moving molecules across the cell membrane to maintain homeostasis. if a cell is unable to take in the materials it needs or remove what it does not need, the cell may die. this inability of cells to maintain homeostasis may cause sickness or even death of an organism. why is it important that the cell membrane is highly selective? to move materials around inside the cell. so that proteins and lipids can attach to the membrane where needed. to prevent certain molecules from entering or exiting the cell. so that the cell wall is stabilized and maintains its rigidity.

Explanation:

The cell membrane's selective - permeability is crucial for maintaining homeostasis. It controls the movement of substances in and out of the cell. If it fails to function properly, it can disrupt the internal balance of the cell, leading to illness or death. This is important because proper substance transport is essential for cell survival and the overall health of the organism.

Answer:

To prevent certain molecules from entering or exiting the cell.
