Final answer:
The extracellular matrix, composed of glycoproteins and proteins like collagen, provides structural integrity and facilitates communication among cells, unlike the cell wall in plants. It interacts with the plasma membrane through specific proteins. Hence, the extracellular matrix is the correct term for the described organized network outside the plasma membrane.
Step-by-step explanation:
An organized network of extracellular materials found beyond the intermediate vicinity of the plasma membrane is best defined as the extracellular matrix (ECM). The ECM is composed of glycoproteins like fibronectin and proteoglycans, and also contains the protein collagen, which provides strength to the tissues. It not only helps in maintaining the structural integrity of cells within a tissue but also facilitates communication between them. This matrix is especially critical for animal cells and some protozoans that lack cell walls for structural stability.
The plasma membrane forms a concise boundary and plays a crucial role in cellular protection and control of the passage of materials. The ECM interacts with the plasma membrane through integrin proteins, which further connects to fibronectin and allows for a robust and dynamic environment within the tissue.
While structures like the cell wall are found in plant cells and provide similar structural support, the extracellular matrix is distinct in functionality and composition and is not the same as the cell wall. Therefore, option 2) Extracellular matrix is the correct answer to what could be defined as an organized network of extracellular materials surrounding cells.
