You can adjust the fine focus knob to bring the onion into sharper focus. If the image is still not clear, you may need to also adjust the condenser or the diaphragm to optimize the lighting.
You should adjust the fine focus knob to sharpen the image when viewing the onion cell under high-power objective (HPO) on a microscope. Rotate the knob gently to focus the specimen until the image appears clear.
Ron is observing an onion cell on a slide under a microscope. He sees chromatids being pulled to opposite ends of the cell. Which phase is he seeing?
Under a compound light microscope, an onion cell will appear as a rectangular shape with a distinct cell wall and nucleus. The cell cytoplasm will be visible, with small structures such as vacuoles dispersed throughout. The onion cell may also have a clear membrane visible around the cell wall.
To prepare an onion cell slide for microscopic examination, first peel off a thin layer of the onion skin. Place the thin layer on a microscope slide and add a drop of water to the onion skin. Gently place a coverslip over the onion skin to create a flat surface for viewing under the microscope. Finally, carefully place the slide on the microscope stage and adjust the focus to observe the onion cells.

The hypothesis of observing onion cells under a microscope could be that the onion cells will have a distinct rectangular shape and contain a visible nucleus.
When observing an onion cell under the microscope, it appear to be long an oval in shape. Staining the cell will make the chromosomes attain a deep purple color.

Some of the best stargazing spots for observing celestial bodies under a clear dark sky include Mauna Kea in Hawaii, Atacama Desert in Chile, and Cherry Springs State Park in Pennsylvania. These locations offer minimal light pollution and optimal conditions for viewing the night sky.

Onion are under the soil.So they do not get sunlight for photosynthesis
Yes, when observing an onion cell under a microscope before and after applying a stain, such as iodine, noticeable changes can occur. Initially, the cell appears as a clear, colorless structure, but after staining, the cell walls and organelles become more defined and visibly colored. The nucleus, in particular, stands out, making it easier to identify the cell's components and overall structure. This contrast enhances the visibility of cellular details that were not apparent in the unstained sample.
