Cell-cell signaling
Cell-ECM attachment
Cell-cell attachment
Water flow
Control of cell division
Regulation of turgor pressure

Answer 1

Cell junctions have multiple functions, including cell-cell and cell-ECM attachment, as well as control of cell division.

Step-by-step explanation:

Cell junctions are specialized structures that connect neighboring cells and play a crucial role in maintaining tissue integrity and function. They serve several functions, including:

1. Cell-cell attachment: Cell junctions help cells adhere to one another, forming tissues and providing structural support.
2. Cell-ECM attachment: Some cell junctions anchor cells to the extracellular matrix (ECM), which is the supportive network surrounding cells.
3. Control of cell division: Certain types of cell junctions regulate the proliferation of cells, helping to control and coordinate cell division within tissues.

These functions contribute to various cellular processes, including defense, cell-cell signaling, water flow, and regulation of turgor pressure. However, these specific functions are not directly associated with cell junctions themselves.
