Weismann‚ who noted that two cell divisions were necessary to transform one diploid cell into four haploid cells if the number of chromosomes had to be maintained. In 1911 the American geneticist Thomas Hunt Morgan observed crossover in Drosophila melanogaster meiosis and provided the first genetic evidence that genes are transmitted on chromosomes. The term meiosis was introduced to biology by J.B. Farmer and J.E.S. Moore in 1905 Meiosis i/maɪˈoʊsɨs/ is a special type of cell division necessary for

MAKES VINCA PLANTS GROW THE BEST? My Science Experiment! The experiment is to take 4 Vinca plants‚ which are about the same size‚ health‚ and flowering stages and find out which one will grow the best. Each of the plants will have 75 ml of a liquid daily for 10 days. My Grandma bought them from Lowes on September 20‚ 2011 for me. Breakdown of the plants are as follows: Control plant will get tap water. Plant A will get Milk from the refrigerator. Plant B will get

ABSTRACT The exercise was about the techniques in proper sectioning of plant tissues and staining techniques so that the study of plant structure will be easier. In free hand sectioning‚ the plant organ must be 45° upright and is held between the thumb and the base of the forefinger. A razor blade was used to cut the plant thinly in cross sections. Obliquely cut tissue is a big mistake since the surface of the tissue will not be even upon viewing under the microscope. Iodine-Potassium-Iodide

EXPLORING THE EGG CELL By: Christina Vu SNC2D3 Mr.Ram FUNCTION OF THE EGG CELL: The egg cell is the female gamete used for sexual reproduction. The egg cell is responsible for providing half of the genetic material required for reproduction. When the egg cell joins with the sperm cell.... The egg cell is large and bulky structure which allows the sperm cell to get in easily. WHAT ORGANELLES DOES AN EGG CELL HAVE AND THEIR FUNCTION? Mitochondria: Produces energy for the cell by a process called

Introduction For the past 30 years Scientist have searched desperately for the answer to salt toleration within plants. The damaging effects of salt accumulation in agricultural soils have influenced both ancient and modern day civilizations alike. Worldwide‚ an estimated 24.7 million acres of once agriculturally productive land are being lost annually due to irrigation-induced salinity‚ according to the U.S. Department of Agriculture. Thus‚ crop production is limited by salinity on 40% of
