Question

what is meant by semipermeable?

Explanation:

A semi - permeable membrane allows certain substances to pass through while restricting others. In the context of cells, the cell membrane is semi - permeable. It permits the passage of small molecules like water, oxygen, and carbon dioxide, as well as some ions, while preventing the free movement of larger molecules such as proteins and polysaccharides. This property is crucial for maintaining the cell's internal environment and enabling processes like osmosis and selective transport.

Answer:

A semi - permeable membrane is one that allows certain substances to pass through while blocking others.
