• 1. Actin subunit
• 2. Intermediate filaments
• 3. Microbubules

Impermeable junction prevent molecules from passing through the intercellular space.

Anchoring juctions bind adjecent cells together by connecting the cytoskeleton

Communicating junctions allow ions and small molecules to pass from one cell to the next. allows communication

Normal

Shrink (Crination)

Explaination: The solution has more molecules and less water so the water is taken out of the cell by osmosis

Bloated and could burst (lyse)

Explaination: The solution has less solutes and more water. The water will move towards the higher concentration of solutes in the cell, making it larger.
