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.

The leaf is arranged like a layered cake. It has a spongy layer, a palisade layer that consists of parenchyma cells and is where photosynthesis happens and an outer layer (the epidermis) with little holes (stomata) that could hold birthday candles.he inside of the leaf looks like this: Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis.
