|
|
Gap junctions prevent the flow of ions and water from one part of the body to another
|
|
|
Adhering junctions (AKA desmosomes) are branched network of proteins that are impermeable to fluids
|
|
|
Gap junctions are connections that directly connect the cytoplasm of two cells
|
|
|
Tight junctions are random, spot attachments between cells that prevent tearing of tissue
|
Detailed explanation-1: -Gap junctions are protein channels that span the intercellular space that connect two cells. They allow cytoplasmic exchange in animal cells.
Detailed explanation-2: -In Summary: Cell Junctions Plasmodesmata are channels between adjacent plant cells, while gap junctions are channels between adjacent animal cells. However, their structures are quite different. A tight junction is a watertight seal between two adjacent cells, while a desmosome acts like a spot weld.
Detailed explanation-3: -Tight junctions form a seal between cells that is so strong that not even ions can pass across it. Gap junctions are involved in cellular communication-not just in epithelial tissue, but in other tissue types as well. Gap junctions are specialized connections that form a narrow pore between adjacent cells.
Detailed explanation-4: -Gap junctions are clusters of intercellular channels that allow direct diffusion of ions and small molecules between adjacent cells.
Detailed explanation-5: -Gap junctions are a type of cell junction in which adjacent cells are connected through protein channels. These channels connect the cytoplasm of each cell and allow molecules, ions, and electrical signals to pass between them.
