Adhering and tight junctions are found at the ____.

A) endoplasmic reticulum
B) nuclear membrane
C) plasma membrane
D) Golgi apparatus
E) ribosomes

Plasma Membrane

The Plasma Membrane is the semi-permeable barrier that encloses the cytoplasm of a cell, controlling the movement of substances in and out, and playing a key role in cell communication and structure.

Adhering Junctions

Specialized structures in cells that function to hold cells together and to facilitate the passage of materials in the spaces between cells.

Tight Junctions

Specialized connections between neighboring cells that create a waterproof barrier to prevent leaking of extracellular fluid.
