Question

Quizplus · Accepted Answer

Interstitial fluid is not a cell structure; it is the fluid that surrounds cells in tissues. The other choices are all main cell structures. Organelles are specialized structures within cells that perform specific functions. The plasma membrane is the outer boundary of the cell, separating the cell from its environment. The cytoplasm is the region of the cell between the plasma membrane and the nucleus, containing organelles and the cytosol (the fluid portion of the cytoplasm).
