Detailed explanation-1: -A, Presence of gap junction–like structures between activated platelet membranes was analyzed with transmission electron microscopy. Arrows indicate gap junction–like structures similar to other cell types.
Detailed explanation-2: -Adhering junctions help to stop substances from leaking across tissues.
Detailed explanation-3: -Functionally, gap junctions in animal cells are a lot like plasmodesmata in plant cells: they are channels between neighboring cells that allow for the transport of ions, water, and other substances 3.
Detailed explanation-4: -Tight Junctions A tight junction is a watertight seal between two adjacent animal cells (Figure 4.29). The cells are held tightly against each other by proteins (predominantly two proteins called claudins and occludins).
