What helps the plasma membrane function? (
chloroplasts and mitochondria
channels and chain-like structures
nuclei and endoplasmic reticula
pumps and gelatin-like material
The correct answer is pumps and gelatin-like material.
Pumps located within the plasma membrane help maintain the cell's internal environment by moving substances in and out of the cell. These pumps are involved in the active transport of various molecules across the membrane.
The gelatin-like material, known as the phospholipid bilayer, makes up the basic structure of the plasma membrane. It is composed of two layers of phospholipids that form a barrier between the cell's internal and external environments.
Chloroplasts and mitochondria are organelles responsible for energy production and are not directly involved in the function of the plasma membrane.
Channels and chain-like structures are not specifically mentioned as essential components for the function of the plasma membrane.
Nuclei and endoplasmic reticula are organelles involved in genetic material storage and protein synthesis, respectively. While they are important for cell function, they are not directly involved in the function of the plasma membrane.
Where are organelles like mitochondria and the Golgi apparatus found? (1 point)
plasma membrane

Pumps store water in the plasma membrane for later use by the cell.
Pumps move substances through the plasma membrane.
Pumps hold the plasma membrane together
The correct statement is: Pumps move substances through the plasma membrane.
