2. Briefly describe the development of vascular tissu by the lateral/vascular cambium of a stem and how that results in the production of wood?
The cambium is a ring of undifferentiated cells. Once a cell moves to the outside of the cambium it becomes phloem. When the cells move into the inside of the cambium - the cells become xylem. Xylem cells die - harden and begin expanding with fresh x

loam
to open - potassium will enter the guard cell. then the guard cell will swell and attract water to the stomata - or area of high concentration. Once the plant has enough water - potassium will diffuse out - the guard cells will shrink - and finally c
