Safety is a basic need of people. Studies show that people who. are continually subjected to stressful situations are more. susceptible to psychosomatic illnesses. Even though it is. possible to adapt to extreme situations over the long term, they. will place a great strain on the individual.
As dendrochronologists, we are more interested in the fusiform initials. The fusiform initials produce secondary xylem and secondary phloem (the xylem and phloem produced during secondary growth). When we study wood or tree rings, we are looking at secondary xylem.As the fusiform initials divide, they produce secondary xylem towards the inside of the cell and secondary phloem towards the outside. Therefore, the vascular cambium (where we find the fusiform initials) is considered to be bifacial.s dendrochronologists, we are more interested in the fusiform initials.

Best Answer: No, they do not. Tree rings are formed by the different growth rate of the tree in spring (rapid, bigger cells) versus late summer (slow. smaller denser cell).In general the spring growth is light colored and the later growth is darker.o many if not most of the tropical trees do not have rings, because they do not lose their leaves all at once and grow at pretty much the same rate year round. There are also some temperate zone trees whose rings are extremely difficult to see, for example some of the maples.
