Which structure separates an animal cell from its surrounding environment? (1 point)

plasma membrane

The correct answer is the plasma membrane. To determine this, you can use your knowledge of cell structure or consult a reliable source such as a biology textbook or reputable website.

The plasma membrane, also known as the cell membrane, is a thin, semi-permeable barrier that surrounds an animal cell. It separates the internal contents of the cell from its surrounding environment, controlling the movement of substances in and out of the cell. The plasma membrane is composed of a phospholipid bilayer, with embedded proteins that play various roles in cell signaling and transport.
