How remarkable it is that the single cell that begins the life of a plant can develop in such an immense variety of ways. Looking at k a newly fertilized cell within an ovary, it is not possible to tell whether it will develop into a tiny alpine plant only a few centimetres high or a giant Californian Redwood (Sequoia sempervirens) over 100 metres tall. The beginnings are the same, but as that one cell grows and divides so the characteristics of the new plant emerge. If it is to be an annual and complete its life-cycle within a year, then there is no need for elaboration of stem cells to give strength and durability. Read the rest of this entry »
