Bamboo
Gramineae, the grass family, has provided civilization throughout history with a bounty of food and many other uses. The top three economically important plants of the world are grasses: wheat corn, and rice. Human kind probably would not have survived if not for the grasses.
The sub-family Bambusoideae, is certainly no exception. These are the bamboos. Consisting of 75 genera and over 1000 species, these unique plants have played a diverse and important role in the development of society, as we know it today.
Morphology
The bamboo plant is constructed of a system of segmented axes. This is depicted by the regular internodal lengths and prominent nodes (McClure 10). They resemble telescoping antennas, but at a constant diameter.
The culm is the above ground stem, this is what is used for most all of the many applications. The culm is woody and either hollow or solid, however most species exhibit some degree of hollowness. The length and thickness of the culm varies greatly between species. Some species can get as tall as 130 feet and be more than a foot in diameter--these have been reported to grow at nearly two inches each hour (Hanke 291). Indeed this would be impressive to see, definitely not like the grasses most of us are familiar with.
Branches, also segmented. arise from the culm. Upon the branches are to be found leaves, with petioles. The fact that the leaves have petioles helps to set the bamboos apart from the other grasses. The leaves and young shoots are the parts eaten by Pandas. The Panda subsists on no other plant or food source. Bamboos alone keep them going strong. More on that later.
New culms, or shoots, are produced from an extensive rhizome system. Simply, rhizomes are modified stems, usually growing underground (Fig. 1). The rhizomes cause the "clump habit" of growth exhibited by the bamboos. "Clump habit" refers to the culms growing in close proximity to each other, such as a "tuft of grass", so to speak. There are basically two types of rhizomes'. pachymorph and leptomorph. Most species exhibit both, to a greater or lesser degree. Pachymorph rhizomes are very compact. They are associated with autumnal growth and produce a dense clump of culms. Leptomorph rhizomes, associated with spring growth, spread a little more. than pachymorph, in some cases a lot more. In other words they are responsible for the lateral growth of a given stand, or clump, of a bamboo species.

Many variations and species of plants can be found all around the world and in different habitats. These variations and characteristics are due to their adaptations to the natural habitat surrounding them. In three of many climatic zones, the arid, tropical and temperate zone, plants that vary greatly from each other are found in these locations. In this experiment, we’ll be observing the connection between the adaptations of the plants to their environment at the Fullerton Arboretum. The arboretum is a space containing numerous plants from different environments. The plants are carefully looked after and organized into their specific habitat. Therefore, we’ll be able to take a look at the plants within multiple
-Red Panda- The Red panda is an amazing creature, it has an incredible sense of balance, and it can reach lighting fast speeds. The Red panda is a omnivore and consumes almost anything that it can eat including bamboo. The Red panda has many symbiotic relationships.
In the following essay I will be explaining Plato’s belief in the Forms and will be critiquing it. The structure of my essay will begin with an explanation of Plato and some background information on him. The third paragraph will contain a brief view into Plato’s view of reality as it pertains to the planes of existence. The fourth paragraph will explore the parallel between mainstream Christian and Plato’s Theory of the Forms. The fifth paragraph reaffirm the information given on Plato’s views into reality and truth, as it pertains to the Theory of the Forms. The sixth paragraph is my critic of the Theory of the Forms, as it pertains to faith and truth. The seventh paragraph is my critics over Plato contradiction over
Over the course of the last few years, there has been much opposition over how sex education should be taught in school. Abstinence should be taught in sex education classes because abstinence is moral. There wouldn't be as many unwed mothers and babies born out of wedlock. Contraceptives that are taught are not guaranteed to protect teenagers from anything, and many people support the teaching of abstinence. It has been said that teaching abstinence- only lessons are leaving students misinformed and mislead, but the instructors have a reason as to why they don’t teach on the contraceptive options. For a long time, sex education classes have been focused on teaching “safe sex” and birth control methods (At Issue: Abstinence Education). What can be taken from this article is all that the classes are doing is teaching students how to possibly keep from contracting an STI (sexually transmitted infection) or getting pregnant. In spite of the fact that many people believe that contraceptives and comprehensive sex education are the best way to teach teenagers about sex, abstinence-only education lessons should be taught instead because teaching about contraceptives and other things that relate to non-abstinence teaching classes does not lower the teen pregnancy rate or any other statistics that are known to the world.
Having performed several further experiments, the Darwins’ stated when seedlings are exposed to a lateral source of light; an (unknown) inducer is transmitted from the upper part to the lower part of the plant, causing a curvature-like appearance (Source 9). Continuing onto Darwins’ discovery, Peter Boysen-Jensen and Arpad Paal determined the substance that caused the bending was due to a chemical present in the plant (Source 7). One year later, scientist F.W. Went concluded the initial discovery, calling the substance responsible for the bending in the plant, Auxin (IAA) (Source 9). Biologists have since recognized the extent of Auxin’s role in plant growth, as well as its location within the plant
Setting off the stem are basal leaves, which emerge from the stem's base as slightly flattened, long, and narrow foliage.
In 1996, Arctic Timber Engineered Woods Division, a highly mature business unit, faced a market downturn and began losing millions of dollars each month. Before becoming the President of the Engineered Woods Division, Bjorn Gustavsson had already determined that the company could not sustain its commodity business and was not aligned with the new direction devised by Peter Hammarskjöld, the CEO of Arctic Timber. According to Gustavsson, in order to prosper in a more challenging market environment, developing a specialty business was the only viable approach. The goal was to shift 50% of its commodity business into undetermined specialty by 2000. However, the Division had shifted only 10% of its business to specialty products by 1997.
Not only expecting the reader to share the same idea that comprehensive sex education is the more beneficial alternative, the authors also believe the reader considers the rate of teenage pregnancy in our country as a bad thing and that there needs to be some sort of action to decrease it. To assume that the reader believes teen pregnancy is bad is a safe assumption to make. Culturally, in the United States, teen pregnancy is not the norm. Although it may be safe to assume that teen pregnancy itself is bad, it is not as safe to assume that abstinence-only education is completely ineffective. Like the authors sated, there could be a lot of opposition to teaching middle school and high school students how to properly use contraception. Many people reason that showing students how to safely and knowledgably prevent pregnancies and STDs will only increase sexual behavior among teenagers (1). In addition to the warrants the authors make, the backing used to support their assumption that abstinence-only education is not effective is in the form of national data on the public opinion of adults that support comprehensive sex education programs. 82% of adults, ages 18 to 83, support comprehensive sex education while only 36% support abstinence-only education (8). The authors’ backing for this warrant is credible knowing that it comes from a sophisticated
45, is described as a focus on the well-being of the patient and involving a team of health professionals to provide education and health promotion to the patient and patient’s family and collaborate together to decide the best choices for the betterment of the patient. In our K12 child nutrition program, our patients are referred to as students. Our students range in age from three years old to 18 years old. The USDA federally-funded meals are not a patient-centered type of care as it is a blanket-mandate for all K12 students in the US. Even though this mandate is not patient-centered care, the reason for this mandate is to provide all school aged children access to healthy meals not only during the school year but, also during the summer months when school is not in
Currently, the United States is one of the most industrialized countries in the world, yet when it comes to the subject of sex, we are still probably one of the highest when it comes to pregnancy and STD rates among teens. Because of this, there are many views that people hold on how to stop it and what is correct and what’s wrong. Between a comprehensive sex education and abstinence only, there needs to be a solution that can reduce the amount of unplanned pregnancies and STD’s going around in teens for their safety and other results that come from the common lack of knowledge that is given to teens today.
“10,000 young people contract a Sexually Transmitted Disease, more than 2,400 teens became pregnant and about 48 contract HIV” (Ballard and Ginsburg). Teens should know the risk of STD’s that can occur to them along with the tragic physical and emotional cost. No teen should find themselves in a situation where they feel uneducated or unprepared on the subject of sexual relations. Abstinence education will help give a better understanding to the many pro and cons that come with sex. Many times when the topic is not covered, it results in negative outcomes due to the lack of knowledge. Abstinence education and providing condoms should be allowed in today's society to help give students a better understanding so they are prepared to make make
The United States is notoriously known for having the highest rate of teen pregnancy and sexually transmitted diseases among developed countries. To reduce these rates, the U.S government funded abstinence-only programs for the youth. Many have speculated whether abstinence programs are the best approach to lowering teen pregnancy and sexually transmitted diseases. Although there is enough data and research showing that comprehensive sex education is best, Kathrin F. Stanger-Hall and David W. Hall continued to provide data on how abstinence-only education affects the youth.
In America, a multitude of studies has concluded that abstinence-only sex education is ineffective in comparison to comprehensive sex education. Moreover, proponents of comprehensive sex education claim, “abstinence-only curricula . . . contain false or misleading public health information” (Beh, Diamond, 2006, p.13). However, the main premise of this paper is to explain that abstinence-only sex education is an appropriate approach to minimizing the rate of teen pregnancies and sexual diseases not if abstinence-only sex education “contain false or misleading public health information” (2006). Educational institutions and their focus are
