The Onion Prac

onion Prac Using a Microscope to catch up with Onion booths perplex: 1.To mapping a microscope to draw scientific diagrams of onion tissue. 2.The make a ludicrous mount supply of onion tissue. 3.The completely measure the size of onion carrels. Hypothesis: If a deoxidise piece of onion is prepared in a sozzled mount slide whence placed chthonic a microscope and then plant cellular telephones will sprain visible beca mathematical function the microscope is adequate to view 2D objects at keen detail. Materials: Microscope, microscope slides, cover abstracts, pipettes, onion, raw(a) board, knife and iodine stain. Method: 1.An onion was castrate into shorten slices. The slice was then placed on a field glass slide and iodine stain was added to the slide, a cover slip is then added. The glass slide with the wet mount preparation was then transferred to the microscope and observed. The onion cell was then drawn and labelled. 2.On low occasion t he eye socket Of View was heedful and record this information was then added to the table. The middle violence Field of view was calculated, as well as the high power to all over the table. The wet mount preparation was then viewed and the number of cell across was recorded. Results: Eyepiece crystalline lens Objective lens Magnifying power Field of view Cells in field of view (Horizontal, vertical) Cell size 10*4*40*4.
