What hollow, membrane-bound structure is permeable to water?

A) Vacuole
B) Nucleus
C) Cell membrane
D) Endoplasmic reticulum

Answer :

Final answer:

The cell membrane (C) is the hollow, membrane-bound structure permeable to water. In plant cells, vacuoles (a) serve functions similar to lysosomes. The endoplasmic reticulum is part of the endomembrane system, focusing on producing and transporting materials.

Explanation:

The hollow, membrane-bound structure that is permeable to water is the cell membrane (C). The cell membrane surrounds all living cells, providing a barrier that manages the entry and exit of substances, including water. It is composed of a phospholipid bilayer with embedded proteins that facilitate its permeability and function.

The membrane's fundamental structure is similar across various organisms, though the function can vary drastically because of the different types of proteins and lipids present. In plant cells, the function of the lysosomes is carried out by vacuoles (a). Vacuoles can store nutrients, waste products, and contribute to the degradation process similar to lysosomes in animal cells.

The endoplasmic reticulum (ER) is part of the endomembrane system that includes the Golgi apparatus and vesicles, which are involved in producing, packaging, and exporting cellular products. The ER, however, is not specifically known to be permeable to water as its function relates more to synthesis and transport of materials within the cell.
