When an onion slide is placed under a microscope, you can observe the cell structure, cell walls, cell membranes, and possibly the nucleus of the onion cells. The cells will appear as small, rectangular shapes with distinct boundaries. Additionally, you may see any organelles present within the cells.
What else can I help you with?
What are the key characteristics observed when examining onion cells under a microscope labeled?
When examining onion cells under a microscope, key characteristics observed include a rectangular shape, a cell wall, a large central vacuole, and a distinct nucleus.
What are the key features that can be observed when examining an onion cell under a microscope, and how are these features labeled for identification?
When examining an onion cell under a microscope, key features that can be observed include the cell wall, cell membrane, cytoplasm, and nucleus. These features are labeled for identification based on their distinct shapes, sizes, and locations within the cell.
What can be observed when examining an onion under a microscope labeled with specific markers?
When examining an onion under a microscope labeled with specific markers, one can observe the different cell structures and components of the onion, such as the cell walls, nuclei, and cytoplasm. The markers help to highlight and distinguish these structures, allowing for a more detailed and precise analysis of the onion cells.
What are the key characteristics of an onion cell as observed under a microscope?
The key characteristics of an onion cell observed under a microscope include a rectangular shape, a cell wall that appears as a thin, clear outline, a large central vacuole that takes up most of the cell's space, and small, dark-stained organelles called nuclei.
When the onion cell is placed in the microscopewhy is it not good to tilt the microscope?
Tilting the microscope with the onion cell slide on it can cause the slide to move out of focus or fall off, potentially damaging the sample. It's important to keep the microscope level to maintain the proper focus and alignment of the sample for observation.

Why is glass placed over the onion skin when under a microscope?
It is to protect it while you are examining it. However, I would like to know why this is under Horse Tack?
What can be observed under the microscope when examining an onion root tip slide?
When examining an onion root tip slide under a microscope, you can observe the different stages of cell division, such as interphase, prophase, metaphase, anaphase, and telophase. This allows you to study the process of mitosis and observe the structure and arrangement of the cells in the root tip.
Introduction in an onion and cheek slide in a biology practical?
In an onion slide preparation, thin layers of onion cells are placed on a slide, stained, and observed under a microscope to study cell structure. On the other hand, a cheek slide involves gently scraping cells from the inside of the cheek, staining them, and examining them microscopically. Both slides are commonly used in biology practicals to observe and compare plant (onion) and animal (cheek) cell structure.
What would happen if an onion is placed in water?
Nothing. The onion will get wet.
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 part of an onion cell can you identify?
Given a good microscope I can identify all parts of an onion cell.
Did you observed any change in the image of onion cells before and after starring?
In cooking, the onion would caramelize.
