An overview of plant cell walls
By: Erich Rosenberger M.D.
It may seem somewhat obvious to say that plants and animals are different. Any six year old can tell the difference between a tree and a dog. But those differences are far deeper than just what the organisms look like. The very cells that plants...

Transpiration in plants explained
By: Sammy Stein
