The correct answer is "active transport is ATP dependent whereas in passive transport molecules use kinetic energy to move across the membrane." in active transport cells use molecules embedded on the cell membrane called carriers in the presence of energy. cells use energy and carriers because molecules must move against concentrated gradient inside the cell. on the hand, passive transport is a process by which molecules move from the region of high concentration to the region of low concentration across plasma membrane until balance is obtained on both sides of the membrane. once equilibrium has been achieved in passive transport the movement of molecules stops.

Answer:columnar describes cell shape.
Simple describe the number of layers
Explanation: epithelial tissues are one of the four major tissues of the body.the others being nervous, muscular, connective tissues.
Epithelial tissues are made up of thin cells that cover the external and internal surface of the body.
The cells may form one layer or more and they occur in several shapes.if they form one layer ,it is called simple.if they form several layers,it is called stratified.
Some are called pseudo-stratified because the cells occur with varying lengths and give the impression of stratified but they are actually made up of one layer.
Simple columnar epithelium is a single layer of tall, closely packed cells. They possess cellular extensions ,such as microvilli in the small intestine, or the cilia in the female reproductive tract.
