27. Briefly describe the development of vascular tissu by the lateral/vascular cambium of a stem and how that results in the production of wood?
grows back every year
1
conduction and absorption
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
28. The oxygen liberated by green plants during photosynthesis comes from ___?
