Essay on Drug Abuse and its Prevention Essays Essay on Drug Abuse and its Prevention Essay Essay on Drug Abuse and its Prevention Essay Drug Abuse Essay A drug is a substance which may have medicinal, intoxicating, performance enhancing or other effects when taken or put into a human body or the body of another animal and is not considered a food or exclusively a food. I chose drugs that impact me a lot. It’s a sad fact that drugs are being abused among people not only in our country but also it is practiced by others especially the teenagers in our generation maybe because the lack of attention of parents to children or the friends were bad influence, but I believe it’s not excuse to be involved in such a situation like this. It is the choice of an individual whether he/she will be influenced by or follow what others do to make their lives miserable. Drug abuse is what I would consider a pretty severe problem we have here in the Philippines. There are many different types of drugs such as marijuana, cocaine, ecstasy, and heroine to just list a few. These drugs are all fairly simple to produce. Teenage drug abuse Teenagers use drugs because they want to fit in. No one wants to be the only one not participating. No one wants to be left out. So sometimes they make bad decisions, like taking drugs, to cover-up their insecurities. * Because they want to escape or relax. * Because they think it makes them seem grown-up. * Because they want to rebel. Sometimes people turn to drugs not so much for themselves, but to make a statement against someone else, such as their families or society in general. * Because they are curious. Adolescents are curious about having new experiences. Seeing someone doing drugs makes them more curious to know how drugs will make them feel. It is important that kids are kept away from this type of environment. * Because of the Peer Pressure * Emotional pressure. Loneliness and depression raise emotional pressure, and some teens seek a chemical solution to this problem. * Because they are bored Often-bored-teen are 50 percent more likely than not often bored teens to smoke, drink, and use illegal drugs. Teens who cant talk to their parents are more likely to feel isolated, and use drugs. * Because they want attention. Ways to prevent drug abuse The reasons above should never be an excuse to abuse ourselves. While it’s practically impossible to prevent anyone and everyone from using drugs, there are things we can all do to avoid drug and/or alcohol abuse. By sharing this knowledge with those closest to you, you yourself may be able to prevent them from doing drugs, too. Good communication with all family members, especially with our parents would be one of the effective ways for us not to sort on taking drugs when it comes to dealing with our problems.

Living and Non-Living Cells and Tissues in Trees

Living and Non-Living Cells and Tissues in Trees Only 1 percent of a dormant mature tree is biologically living while the rest is composed of non-living, structural wood cells. In other words, very little of a trees  woody volume is composed of living, metabolizing tissue; rather, the major living and growing portions of a tree are leaves, buds, roots, and a thin film or skin of cells just under the bark called the cambium. There are other living cells that are important for tree growth within the different parts of trees, especially in root tips, the apical meristem, and leaf and flower buds; however, these living cells make up a very small percentage of the total volume of a trees cells. Instead, non-living or dead cells comprise most of the volume of a tree, providing vital structural support for the living cells. Interestingly enough, trees start out in life as a germinating seed with every living cell in hyperdrive, but  as a tree seed becomes a seedling, then a sapling, then a mature tree, its living contents become less and less as a percentage of the total volume. Trees increasingly lose their living cytoplasmic cells as metabolism ceases in each cell, and although they are no longer alive, these non-living cells now provide protection, transportation, and physical support for the living ones. The Vital Role of Non-Living Cells Without the support and structure provided by non-living cells,  trees would likely die  and certainly wouldnt grow quite as large as they do. This is because non-living cells provide a vital role in the process of  how a tree grows  - from the heavy lifting of holding up the tall branches to the trees bark, which protects the thin layer of living cells underneath. This supporting and protective wood is created by cambial-hardened cells produced on the inner and outer cambial layer and sandwiched between the outer cambial layer. As a result, the bark of a tree is a product of the ongoing process of creating  sieve tubes to transport water and nutrients from the leaves to the roots and back. The sound, non-living cells of a tree are very important to helping a tree stay protected, and the bark and structural cells serve as a line of defense against insects and disease that could affect the vulnerable living tissue of the cambium that maintains life throughout the tree. New cells are formed and living cells cease metabolization as they transform into transport vessels and protective skin, creating a cycle of creation, rapid growth, slowing metabolism, and death as the tree climbs ever-higher into a healthy, full plant. When Wood Is Considered Alive and Dead For most intents and purposes, wood is considered to be the product of living cells in trees harnessing the environment around them to make proteins and form protective vessels and shells for the trees sustained growth. Wood is only technically considered dead when its separated from the tree itself, as it still serves a vital role in the plants life when attached to living cells in the tree. In other words, although wood is largely made of non-living cells - cells that no longer reproduce but instead transport nutrients to living cells - it is still considered alive if it is attached to the tree itself. However, if a branch falls off or a person cuts down a tree, the wood is considered dead because it no longer transports living matter through itself. As a result, wood that has been separated from a tree will dry up as the protoplasm hardens and the protein turns into the wood one might use in a fireplace or for building a shelf. This wood is considered dead, though the piece it was once attached to - if still attached to the tree itself - is still considered alive.
