bio lab 6 essays Microscopy and the Electron Microscope Humans have been magnifying objects for centuries by using lens. Using lens to magnify objects has helped mankind know more about the cell theory and ways of life. Zacharias constructed the first compound microscope. Robert Hooke used the microscope to examine slices of cork. He noticed many little boxes and called them cells. Cells are the building blocks of life. We would not know as much about cells as we do with out microscopes. It is important to know about the different types of microscopes and how they function. CD player, Individualized Biology lab book, pen, and your brain. Objectives: (See page 2 of Individualized Biology Unit 9 Script.) Anton van Leeuwenhoek is considered to be the father of bacteriology. He used a simple microscope consisting of one lens to observe bacteria and other unicellular microorganisms. He grinded the lens he used, so that the lens had great curvature. He reached magnifications of 270 diameters. This was the most reached from his time. Magnification increases the visibility of what ever detail the objective lens can reveal. There is a significant relationship between wave length and resolving power. Wavelength is the distance between corresponding points on two successive waves. The shorter the wave lengths are used, the greater the resolving power is. Two objects that are closer together than one half the wave length of light used can not be seen as separate objects. There are several ways to increase the resolving power. You can use a shorter wave length, project on to screens, use quartz lens, use ultraviolet light, or use an objective lens that can accept a greater cone of light. The wavelength that would give the best resolving power for a light microscope is blue. Light source has a great effect on a microscope. The bright fi ...

Also, the English and Spanish words for particular fruits may not always be an exact match, sometimes because two similar species of fruits may share a name. For example, what is known as un arndano in Spanish goes by several different names in English, such as huckleberry, bilberry, blueberry, and cranberry. One common source of confusion is that a limà ³n can refer to a lemon or a lime depending on the region. The names of many fruits are similar in English and Spanish, either because they have a common origin (such as from Latin) or because the English borrowed a fruit name from Spanish.The trees or other plants that produce sometimes have distinctive names related to the name of the fruit.Some fruits have names that are understood only in certain localities. Common Foods Made With Fruit apple cider - la sidra sin alcoholapple crisp, apple crumble - el crujiente de manzanaapple pie - el pastel de manzanacompote - la compotafruitcake - el pastel de frutafruit cocktail - el cà ³ctel de frutasfruit salad - la ensalada de frutassjam - la marmeladajuice - el jugo, el zumopeach cobbler - el pastel de durazno, tarta de duraznostrawberry sundae - el sundae de fresa, el helado con fresas Fruit Names English and Spanish Share English and Spanish share the names of various  fruits for one of two reasons. Either the English name came from Spanish, or English and Spanish gained the name from a common source. There are no fruits on this list in which the Spanish derived from English, although its likely that kiwi, a word from Maori, was adopted because of U.S. English influence. Here are etymologies of several Spanish-derived fruit names we use in English: papaya - Spanish picked up papaya from Arawak, an indigenous language of the West Indies, and it spread to English via the shipping industry.pear - The English name for the fruit comes from the Latin pera, which is also what its called in Spanish.plantain - Plantain has two meanings - a fruit similar to a banana and a type of flat-leaved weed. Both are called pltano in Spanish. The words with the first meaning probably came to us via Spanish, which picked up the word from the West Indies, while the word with the second meaning came indirectly from Greek.tomatillo - Tomatillo in Spanish is tomate with the diminutive suffix -illo. Other Spanish food words using this suffix include tortilla (omelette or tortilla, from torta, cake), mantequilla (butter, from manteca, lard or some types of butter), and bolillo (bread roll, related to bola, ball).tomato - At one time, the tomato was called a tomate in English, the same as its Spanish name. The Spanish in turn came from Nahuatl, an in digenous Mexican language, which used the word tomatl. The tl ending is very common noun ending in Nahuatl. Sources for some of the other fruit names include Italian (cantalupo and cantaloupe), Latin (pera and pear), and Arabic (naranja and orange). Words for Fruit-Producing Plants Although the words for tree and bush are rbol and arbusto, respectively, many of them that produce fruit have names related to the name of the fruit. Here are some of them: apple tree - el manzanoblackberry bush - la zarzacherry tree - el cerezograpevine - la vid, la parralemon tree - el limoneroorange tree - el naranjopear tree - el peraltomato vine - la rama de tomate
