Final answer:
Desmosomes and gap junctions are the two types of cell junctions that are localized spots and are not occluding junctions. Desmosomes provide strong adhesion, while gap junctions allow for the passage of small molecules between cells.
Step-by-step explanation:
The two types of junctions between cells that are not occluding junctions, but localized spots, are desmosomes and gap junctions. Desmosomes act like spot welds, forming strong points of adhesion between cells, using cadherin proteins to link adjacent cells at localized patches on the cell membrane. In contrast, gap junctions create localized intercellular passageways that allow for the exchange of small molecules and ions between neighboring cells, facilitating direct cell-to-cell communication.
