Biology Question on Structural Organisation of Animals and plants
Which type of cell connections generally prevent materials from passing between cells?
A
Hemidesmosomes
B
Gap junctions
C
Desmosomes
D
Tight junctions
Answer
Tight junctions
Explanation
Solution
Tight junctions limit the passage of molecules and ions through the space between cells. So, most of the materials must actually enter the cells in order to pass through the tissue. This pathway provides tighter control over the substances that passed through it. In this way they prevent materials from passing between the cells.
