Which of the following cell-cell junctions forms a seal between cells that prevents leakage?
A
Adherens junctions
B
Tight junctions
C
Gap junctions
D
Plasmodesmata
Verified step by step guidance1
Understand the function of each type of cell-cell junction mentioned in the problem.
Adherens junctions are primarily involved in connecting the actin cytoskeleton of one cell to another, providing mechanical stability.
Gap junctions allow for communication between cells by permitting the passage of ions and small molecules.
Plasmodesmata are channels between plant cells that allow for transport and communication.
Tight junctions create a seal between adjacent cells, preventing the passage of molecules and ions through the space between cells, thus preventing leakage.
