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.

Phloem transports sugars, proteins and minerals around the plant. Unlike the xylem where flow is only one way, from the roots up, phloem can move sugars both up and down the stem. In flowering plants, phloem is contains four cell types: sieve tube members, companion cells, fibres and parenchyma.ellulose is similar in form to complex carbohydrates like starch and glycogen. These polysaccharides are also made from multiple subunits of glucose. The difference between cellulose and other complex carbohydrate molecules is how the glucose molecules are linked together.
