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.
What else can I help you with?
What Onion epidermis is a suitable tissue to use for observing cellular structures with a compound light microscope because this tissue is thin enough to?
Onion epidermis is a suitable tissue for observing cellular structures with a compound light microscope because it is transparent, allowing light to pass through easily, and the cells are thin enough to view individual cells and structures such as cell walls, nuclei, and chloroplasts. Additionally, the large size of onion cells compared to other plant cells makes it easier to study their internal structures.
When onion cells are observed with a compound light microscope which laboratory technique is used to make nucleus more visible?
Staining with a dye such as methylene blue or eosin can be used to make the nucleus more visible in onion cells when observed under a compound light microscope. The dye selectively binds to different cellular components, allowing for better contrast and visibility of the nucleus.
What plant organelle is missing from the onion cell?
The onion cell is missing chloroplasts, the organelles responsible for photosynthesis in green plants. Onion cells do not contain chlorophyll, so they do not require chloroplasts for photosynthetic processes.
How do you think the tip of a live onion can be prepared so that you can observe it under a light microscope?
You place it in a slide and you press it slowly against your body and down your leg. Once the smell is on your body, remove it and place under microscope. Make sure the light is on max for high visibility. Source: Facebook
What is the process of preparing an onion cell slide for microscopic examination?
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.
When a onion cell is stained with iodine which organelles are you not able to see under a compound light microscope?
Under a compound light microscope, you would not be able to see specific organelles like the lysosomes, peroxisomes, endoplasmic reticulum, and Golgi apparatus in an onion cell stained with iodine. These organelles are typically smaller and/or transparent, making them difficult to visualize with this type of microscope.

What piece of apparatus that you would use to look at closely a onion cell?
To closely examine an onion cell, you would use a light microscope. This instrument allows you to magnify the onion cells, enabling you to observe their structure, including the cell wall, nucleus, and cytoplasm. A prepared slide of onion tissue would be placed on the microscope stage for viewing. Additionally, using a cover slip can help flatten the sample and reduce refraction of light for clearer images.
What compound word ends with onion?
Some compound nouns that end with 'onion' are:green onionred onionSpanish onionVidalia onionwhite onionyellow onion
What is a description of Onion cell?
describe onion cell
How do you look for vacuole at onion cell through light microscope?
You should use iodine to stain the cells. Set the cells on a slide, let them dry you will repeat the process until it is completely covered in iodine and then you will slide it in the stage and then hopefully you will then see the sells of the onion skins.
What part of an onion cell can you identify?
Given a good microscope I can identify all parts of an onion cell.

Why can you see the parts of a onion under a microsope?
You can see the parts of an onion under a microscope because onion cells are relatively large and have distinct cell structures, such as the cell wall, nucleus, and cytoplasm. The onion's transparent cell walls allow light to pass through, making it easier to observe the details. Additionally, when stained, the cells become more visible, highlighting various components under the microscope. This combination of size, transparency, and staining makes onion cells ideal for microscopic examination.
