Final answer:
C. Yes, but to a limited extent. Plants can exchange material through their plasma membrane via plasmodesmata, which connect the cytoplasm of adjacent plant cells.
Step-by-step explanation:
C. Yes, but to a limited extent. While plants have a cell wall that provides structural support and protection, they also have a plasma membrane (cell membrane) that surrounds the plant cells. The cell wall is porous and allows for the exchange of some materials, such as water, ions, and certain small molecules. However, the plasma membrane is the primary site for selective transport and communication with the external environment. It regulates the passage of substances in and out of the cell, controlling the flow of nutrients, gases, and other essential molecules. Thus, while the cell wall does not impede all material exchange, the plasma membrane plays a crucial role in regulating these processes.
