Of course a cell does not defy entropy. It takes in a certain amount of energy, uses that to reduce the entropy of the materials it takes in to make what it "desires". The amount of increase of entropy (disorder) caused by the use of the energy is larger than the amount of decrease in entropy (increased order) of the products of the cells production. It's like running up a downwards moving escalator - you get higher by expending a lot more energy (increasing entropy) than you could recover by going down again once you reached the top.
