Answer 1

The correct answer is "channels and chain-like structures". Channels are protein structures that allow specific molecules and ions to pass through the plasma membrane, while chain-like structures such as the cytoskeleton provide support and help maintain the structure of the membrane. Pumps, gelatin-like material, chloroplasts, mitochondria, nuclei, and endoplasmic reticula do not directly contribute to the function of the plasma membrane.
