Additionally, plants can house animals or provide prey animals with cover and camouflage to prevent them from being over-hunted. They also help create a more sustainable ecosystem. The presence of plants moderates the temperature and mitigates the effects of the wind and sun. The plants in the rainforest keep the rainfall patterns in balance with the rest of the earth's ecosystem ("The Biology of Plants," Missouri Botanical Gardens, 2009).
Even when plants are not directly consumed for food, they can help sustain human beings. Plants hold the soil together and guard against erosion. Plant compost acts as fertilizer for the soil. Plants can be used as medicine in the form of herbs and other medicinal plant derivatives, or as products in the form of rubber, burlap, and cotton. Plants were and are the first source of warmth -- wood is necessary to heat an old-fashioned stove and to build a…...

Plants and Humans
Plants, one of the six taxonomic Kingdoms of different life forms generally accepted throughout the United States, play an important role in the existence of other life forms such as animals. In fact, plants are so important for life on planet Earth that humans could not exist without plants. Photosynthesis, the process by which plants convert sunlight and carbon dioxide into oxygen and water, is responsible for the creation of the Earth's atmosphere; and the life forms that have evolved in it. In addition to creating the environment, plants also maintain that environment by constantly converting carbon dioxide into the oxygen necessary for human survival. Plants also provide the food that is necessary for humans to survive, as well as providing the basis for the survival of other species that are also essential to human survival. In short, plants are indispensable to the human race and people could…...

Disease can also be a worry with Hostas. They are susceptible to certain plant viruses, and these can be serious. Usually, the only cure is to identify and destroy the infected plant before it infects others in the garden. Leaves can also be damaged by chemicals, cold or frost, or by too much sun, resulting in sunburn (Heinke and Martin). As more Hostas are developed, it seems many of these problems will be addressed and Hostas will become even more trouble-free to grow and maintain.
In conclusion, Hostas are the most popular plant in landscaping today. They are beautiful, offer thousands of unique varieties, and are relatively simple for even a beginning gardener to grow and maintain. It is easy to see why Hosta fanciers are so enamored of the plant. The diversity, size, and adaptability of Hostas make them perfect for just about any garden, no matter where it is…...

People without Plants
Biology
When a person goes into the rainforest or the ocean, that person can readily notice that the rainforest and the ocean are teeming with life. An observer of these places will also notice how every form of life works together to sustain the environment. Though human beings build artificial environments such as cities, humans are a part of the ecosystem on Earth, and they participate in this co-dependency on other forms of life to survive as well as to sustain the environment. A form of life that humans are dependent on are plants. Without plants, human beings would have no air to breathe and their respiratory systems would fail. There would exist no human civilizations without oxygen. Perhaps there would be other forms of life in the place of humanity that breathed another gas, but humanity would not exist as we know it today were it not…...

Narcotic plants and stimulants have been widely used in North as well as outh America even before the discovery, 'not only for the purpose of exhilaration or intoxication, but also in connection with the practice of necromancy and in religious rituals and ceremonies accompanying the initiation of boys into the status of manhood.'(afford, 1916: Pg: 387, P.I) Narcotic plants belong to those categories of plants called Psychedelic or Hallucinogenic plants. The term 'narcotic' indicates the presence of certain chemical compounds in the plant compounds that causes the hallucinating effect. Narcotics that cause hallucinations are known by various names depending on its effects - hallucinogens being hallucination generators, psychotomimetics functioning as psychosis mimickers, psychotaraxics being mind disturbers, and psychedelics being mind manifesters.

Why there would be no people without plants
The connection between humans and nature has been a primordial one, actively discussed not only in life sciences but also in literature. Ever since the start of the evolutionary process plants have been an incredible source for food, medicine and even shelter, however the greatest benefit plants have given the human race is oxygen.
Photosynthesis is the process that converts energy in sunlight to chemical forms of energy, which can be used by biological systems. This procedure is carried out by plants and bacteria; a higher form of photosynthesis is completed by algae, cyanobacteria and their relatives (notably known for the photosynthesis in the oceanic ecosystem). These organisms covert CO2 to organic material by reducing this…...

stimuli can affect plant growth rates, robustness, flowering, and even fruit production. We also know that nitrogen is an important part of plant development, and contributes significantly to the thickness, leaf count, and stem width in most plants. A plant that is nitrogen deficient is generally small and develops slowly because it lacks the nitrogen necessary to manufacture adequate structure and genetic materials. This could leave the structure pale green, because it lacks adequate chlorophyll. On the other hand some plants may grow rapidly when supplied with excessive nitrogen. They develop protoplasm faster than they can build sufficient supporting materials in cell walls. The plant may grow weaker and be prone to more pathogens or injuries while developing smaller fruits or fruits with less seeds (Foyer and Zhang, eds. 2010).

Conclusion
The research showed that medicinal plants, commonly referred to as medicinal herbs, have been used by humankind for thousands of years for virtually every type of misery, real or imagined. The research also showed that the resurgence of interest in medicinal plants today relates not only to their potential for providing new medicine preparations, but the fact that there is an enormous amount of money involved as well, with little or none of it being returned by the multinational pharmaceutical companies to the indigenous peoples who depend on these plant materials as a primary source of medicine. In the final analysis, the ancient shamans, witchdoctors and medicine men around the world were clearly on the right track when they observed how these plants affected sick animals, and their trials and efforts at identifying those plants with the most efficacious qualities has provided mankind today with a cornucopia of medicines that…...

Plant Biology
Shoot architecture enhances photosynthesis largely by maximizing the ability of the plant to get sunlight. Obviously light is the crucial resource in photosynthesis, but different plants obtain the resource in different ways. For example, the basic arrangement of leaves on the plant stem (known as "phyllotaxy") is different for every species of plant -- however, in all of these cases the plant has evolved so that the emergence of leaves does not block the available light for leaves above or below. The evolutionary reason for this should be obvious: as leaves exist purely to facilitate photosynthesis, the production of leaves that underperform due to inadequate access to sunlight would be a waste of the plant's resources. We can also see the evolutionary imperative expressed in leaf size: in cold or dry environments without much access to liquid water, the leaf size is drastically shrunken in an attempt to balance…...
earth's rotation affect plant growth?
The seasons of the year are produced by the tilt of the axis of the Earth. The earth's tilt on its axis causes the hours of daylight to shorten during the cooler months of the year. This affects the changing of the seasons and indirectly affects plant growth, as a plant's ability to survive and flourish will depend on the area where it is located and the relative heat or chill of that region and the region's exposure to sunlight. ("ill the equinoxes and solstices switch places in 13,000 years because of the precession of the Earth's rotation axis?" 2005) "Summer in the northern hemisphere occurs at the same time as winter in the south, and vice-versa."

Strategic Defense in the Plant Kingdom
The purpose of this literature review is to detail the different ways plants protect themselves from predators. Knowledge of plant defenses can help boost understanding of more effective means of minimizing pesticide and herbicide use in agriculture or alternatively, to help develop more effective and targeted chemical pesticides and herbicides. Understanding plant defenses requires knowledge of plant biology and their role in their respective ecosystems. Moreover, their defenses ensure the survival not only of individual plants, but of whole ecosystems.
Plants have no immune system, in the same way animals do (Freeman & Beattie, 2008). Instead, they boast "a stunning array of structural, chemical, and protein-based defenses designed to detect invading organisms and stop them before they are able to cause extensive damage," (p. 1). The defenses plants have evolved to ward off predators can be loosely grouped into three categories: surface-based protections (morphological protections such…...

This physiological process allows plants to make their own food. Being able to make their own food through the process of photosynthesis, plants, unlike animals, no longer need to feed on other organisms in order to exist and survive. And since sunlight is required for this essential physiological process to occur, sunlight therefore makes the plants stronger.
Through the physiological process of photosynthesis, plants are able to release oxygen, the presence of which guarantees that existence of life on earth will continue. According to Hackel, the oxygen in the earth's atmosphere was released over 3,500 million years ago through plant photosynthesis and "without plants, there would be no oxygen in the earth's atmosphere." (22) The sun not only makes plants stronger, it also helps ensure that life on this planet continues.
Sunlight is also required by some plants in order to germinate. The sun helps the seeds of plants to germinate.…...

Sayano-Shushenskaya Hydro Power Plant Disaster
Company Background
Sayano -- Shushenskaya hydroelectric power station is geographically located on the Yenisei iver, near Sayanogorsk in Khakassia, ussia. It was the largest hydro electrical power plant in ussian and sixth largest hydro electrical power station in the world, until the accident has occurred. The plant was operated by usHydro, which was established in December 2004 during ussia's privatization movement, however about 60% of its shares are owned by ussian government. The milestone of usHydro operation was that it has recorded the satiation's all-time highest electricity output in 24 hours (usHydro, July 2009). usHydro has 55 hydro plants with the installed capacity of 25.4 GW. The annual energy generation recorded by Sayano-Shushenskaya hydroelectric power station was about 23.4 TWh, which was almost one-quarter of that produced by usHydro's resources for the Unified Energy Systems of ussia and Siberia. The major consumer of the plant was United…...

Organ donation is a process that allows a person to donate their organs to another person. Most organ donation is done after death and can be accomplished either through a person choosing to be an organ donor or by survivors choosing to donate the organs. However, there are some organ donations from living donors, such as kidney transplants. To some people, organ donation is an ethical issue, however the ethical perspectives vary. For some, it is an ethical violation to donate organs and may go against religious norms. For others, it is unethical not to....
