A) mitochondria
B) rough endoplasmic reticulum
C) glycocalyx
D) lysosomes

Accepted Answer

The glycocalyx, a glycoprotein and glycolipid covering that surrounds the cell membranes of some bacteria, epithelia, and other cells, plays a crucial role in cell recognition, including the differentiation between self and non-self cells. This is important in immune responses and in the interactions between cells within an organism.
