Respuesta :
The cell membrane is similar to dialysis tubing. Thus, option A is correct.
What is cell membrane?
The cell membrane is a thin selectively semi-permeable membrane an outer covering of a cell by surrounding cell cytoplasm.
Proteins and lipids are the major components of cell membrane where as the ratio of protein to lipid in cell membrane may vary depending on types of cells.
The most common lipid in membrane is phospholipid, which form a semi-permeable lipid bilayer. Some organelles in a cell are also have its own cell membrane such as nucleus and mitochondria.
The function of cell membrane is to protect the integrity of the internal environment of the cell, act as a base of attachment for the cytoskeleton in some organisms resulted in support cell and maintain its shape.
It helps in transport of nutrients into the cell and transport of toxic
substances out of the cell due to its selectively permeable nature. Thus, option A is correct.
