pumps and gelatin-like material
The correct answer is pumps and gelatin-like material.
To determine what helps the plasma membrane function, we need to understand the role of the plasma membrane. The plasma membrane, also known as the cell membrane, is the outermost boundary of a cell. It controls the entry and exit of substances into and out of the cell, allowing a cell to maintain its internal balance.
Out of the given options, the correct answer is "channels and chain-like structures." Channels are proteins that are embedded in the plasma membrane and act as passageways for specific molecules to move across the membrane. These channels allow for the selective transport of ions and other substances. Chain-like structures, known as cytoskeleton, provide structural support to the plasma membrane, helping it maintain its shape and integrity.
The other options, such as chloroplasts, mitochondria, pumps, gelatin-like material, nuclei, and endoplasmic reticula, are not directly involved in the functioning of the plasma membrane. Chloroplasts and mitochondria are organelles responsible for energy production within the cell. Pumps are involved in active transport processes, which are different from the functions of the plasma membrane. Gelatin-like material, nuclei, and endoplasmic reticula are important components of the cell, but they do not directly contribute to the functioning of the plasma membrane.
So, to recap, the plasma membrane's function is facilitated by channels and chain-like structures.
