Structures and processes involved in the movement of substances into and out of cells. Epithelial cells – Epithelial cells are also referred to as eukaryotic cells. These types of cells have a unique nucleus and contain membrane-bounded organelles. Epithelial cells absorb and secrete‚ and the structures of a cells organelles can be viewed from an electron microscope.

structure of the plasma membrane and explain the process of active and passive transport through the membrane. The plasma membrane is made up of proteins that form pores and channels‚ carbohydrate molecules that are used for cell recognition and cholesterol to provide membrane stability. Phospholipid molecules are the most abundant component found in the plasma membrane. Phospholipids molecules are composed of a phosphate head and a lipid tail; the structure of a cell membrane is a double layer
