The cell membrane does all of the following except:
A. Contains the hereditary material
B. Acts as a boundary or border for the cytoplasm
C. Regulates passage of material in and out of the cell
D. Functions in the recognition of self
Answer (3)
The cell membrane acts as a selective, partially permeable boundary which allows wanted substances to move into the cell and unwanted substances to be kept out. Moreover, cell membranes contain surface antigens, which allow the cells to be identified as "self" by the immune system. The cell membrane does not contain hereditary material.
The cell membrane , or plasma membrane, defines the cell's borders, regulates the passage of material in and out of the cell, and helps in cell recognition. However, it does not contain hereditary material, which is located within the cell's nucleus. ;
The cell membrane serves as a boundary, regulates passage of materials, and allows for self-recognition but does not contain hereditary material. Therefore, the answer to the question is option A. The cell membrane does not contain the hereditary material.
