What cell structures can be seen in a stain onion cell?
The structure that is seen is the cell wall. This keeps the shape of the cell and is only found in plant cells. The organelles that can be see in a stained onion cells all depends on your microscope. Under a x400 light microscope we could see the cell wall, cell membrane, nucleus and cytoplasm,
What does effect iodine have on the onion cells?
Iodine is often used to stain onion cells to make the cell structures more visible under a microscope. The iodine solution will stain specific cell components such as the cell walls and starch grains, allowing for easier observation and analysis of the cells.
What do we expect to see in the onion cell?
In an onion cell, we expect to see a distinct cell wall that provides structure, a large central vacuole that stores nutrients and waste products, and cytoplasm containing organelles like the nucleus, which houses the genetic material. The cells are typically rectangular in shape and may appear somewhat transparent under a microscope, allowing for the observation of these internal structures. Additionally, the presence of chloroplasts is generally absent in onion cells, as they are non-photosynthetic.
Can you clearly see as a structure the cell membrane in check cells and the cell wall inthe onion skin clls?
Yes. If viewed under even a simple light microscope, the cell structure of a cheek cell and the cell walls of an onion cell can clearly be seen.
What structures did you see inside the onion cells and what sre there functions?
Inside onion cells, I observed a cell wall that provides structural support, a large central vacuole that stores water and nutrients, and a nucleus that contains genetic material and regulates cell functions. The cell wall protects the cell and maintains its shape, the central vacuole helps regulate water balance and store nutrients, and the nucleus controls cell activities and gene expression.

What are the structures that can be observed in stained onion cells?
we were able to see the different organells of the cells including cell wall ,plasma membarane,nucleous,cytoplasm mitochondria ,vacoules etc since we viewd from an electo microscope
How do you see cell of onion peel colourfully?
To see the cells of an onion peel colorfully, you can perform a simple microscopy experiment. First, peel off a thin layer of onion skin and place it on a glass slide. Stain the onion cells with a dye like iodine or methylene blue to enhance contrast. Then, observe the slide under a microscope; the dye will highlight the cell structures, allowing you to see the cells more vividly.
Why is iodine used when observing onion cells?
AnswerIodine was used to stain onion epidermal cells so you could see the cells more clearly and examine them. Naturally, the cell parts are difficult to see because they are clear.You put iodine on onion cells in order to make parts of the cell which were translucent, more visible. This is because iodine stains starch present in the 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.
Why cant you use methylene blue when staining onion cells?
Methylene blue is not suitable for staining onion cells because it does not effectively bind to the distinct cell structures present in onion cells, such as the cell walls and nuclei. Toluidine blue or safranin O are commonly used stains for onion cells as they provide better contrast and visibility of cell structures.
Parts of an onion skin cell that you can not see?
the chloroplast

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.
How much are these onion cell magnified?
It depends on the strength of the lense you are using and how high you set the magnification of the microscope.At 40X magnification, the microscope enlarges a 2 mm part of the onion and at 100X the microscope enlarges 0.8 mm of the cell. At both 40X and 100X you can online see a zoomed out image of the cells.At 400X, the microscope enlarges a 0.2 mm part of the cell. The individual cell is more clearly seen.At 1000X magnification, the microscope enlarges a 0.08 mm part of the onion cell. At this level of magnification the nucleus of the onion cell can be seen.This link shows different magnifications of the onion cells.
Stain name used for onion cells?
safranine stain is used to stain onion cells
