Ethan Peck Botany 11/10/09 “Vita-light verse Normal” {draw:frame} Figure 1. Average plant height for fast plants grown under two light treatments regular lighting and Vita light bulbs. My hypotheses for plant height was as follows: I belived that vita lite was going to be tremendously better than the normal lighting due to manufacture claims but as the evidence shows normal lighting did better. For reason I that could of went either way. {draw:frame} Figure 2.
But in some species there are many more than six present in a flower (see, for example, the spider tree flower, below). Collectively, the stamens are called an androecium (from Greek andros oikia: man's house). The column formed from the fusion of multiple filaments is known as an androphore. The anthers are bilocular, i.e. they have two locules.
"A Brief History of Sugar." A Brief History. 11 Oct 2008 <http://www.irish- sugar.ie/noframes/nf-pages/nf-hist/nf-hist.htm#productn> Sugar cane is a member of the grass family. The sugar cane has hollow stalks filled with a sweet juice or sap from which sugar can be extracted and can grow to 15 feet tall. It grows best in very warm climates and is ready to harvest after 10 to 20 months.
Some of the plants in the Rideau River are carnivorous. o Yellow-flowered bladderwort captures and digests microscopic invertebrates. o Invasive plant species: Eurasian Water Milfoil is a plant that grows in thick tangles. These plants can reproduce very quickly because they do not rely on seeds alone to spread. Eurasian water milfoil can grow out of clippings from the plant.
Like a tomato, you can know when it is ripe by looking at the color or by squeezing it, the hardness will indicate the ripeness of the fruit. In addition, when I first sliced and opened it, it has an orange color, which looks like a sunset. The smell of persimmons is not aromatic; it does not have an aroma that attracts people to eat it. When it is sliced, however, you can actually smell the fragrance of the fruit spreading in the air. Its smell, in my opinion, is like that of an apricot and mango combined.
Pollan outlines the history of four crops-- apples, tulips, marijuana and potatoes. He discusses how humans have influenced their evolution and how crops have influenced our cultures. He recounts real stories, rather than myths, about such characters as “Johnny Appleseed,” an eccentric loner who helped colonize various apple crops across a new America. As a result, we do not have as many varieties of apples as once existed, and the ones we have are less resistant to pests. Pollan, Michael.
Stevia Alison Brayton Ilab2 (SCI-228) DeVry University Who would have thought that a leaf to a flower or a weed would be used as part of a sugar substitute; Stevia uses leaves from a bush called the stevia bush to make a sweetener. The species Stevia rebaudiana its botanical name, is derived from a plant in the chrysanthemum family grown primarily in South America and Asia. The plant’s intense sweetening qualities are complex molecules called steviosides that are glycosides made of glucose, sophorose and steviol. This very same bush is also used in traditional medicine in the region for burns, colic, stomach problems and sometimes even used a contraceptive. According to an article that I read Stevia is a no calories sugar substitute that happens to be 200 times sweeter than sugar in the same concentrate.
The species, often called sweet leaf or sugar leaf, is widely grown for its intensely sweet leaves. A component on the leaf called stevioside is extracted and manufactured into the calorie-free sweeteners you see in stores. Originally Stevia was only available as a "dietary supplement" in the U.S. In 2008 the federal Food and Drug Administration (FDA) granted Generally Recognized as Safe (GRAS) status to rebaudioside A, one of
5Q)Give two examples of the benefits of introducing some nonnative species. A)Introduced species such as corn, wheat, rice, and other food crops, as well as cattle, poultry and other livestock provide more than 98% of the U.S. Food supply. Simalarly, nonnative tree species are grown in 85% of the worlds tree plantations. Q)Give two examples of the harmful affects of nonnative species that have been introduced Deliberately, and accidentally. A)An example of a harmful effect is that they may not have any natural predators.
In the same species broccoli closely resembles cauliflower. Both plants‘ flower and stalk are used for food. The outstanding difference is color; cauliflower is white in color with light green leaves, whereas broccoli is dark green. Area of Origin and History Broccoli is native to the eastern Mediterranean and Asia Mira. It is known that it evolved from a cabbage from the ancient Etruscans, who were considered to be horticultural geniuses.
