Why is salt not allowed to pass through the cell membrane?

Salt molecules are much smaller than starch molecules and can pass through more easily. ... Thus, they are quite large molecules in contrast to the relatively small salt molecules. The smaller salt molecules pass through the membrane easily, but the larger starch molecules cannot pass through the membrane.

The correct option is Organelles.

The generalized name for the specialized structures present inside a typical cell is Organelles. These are the specialized membrane bound ( made up of lipid membrane) structures present in the cells, which serve specific functions to the cell. They are also called the sub-cellular compartments of the cell.

Example of organelles- Ribosomes, Mitochondria, Endoplasmic reticulum, Lysosomes, Golgi complex.
