What parts of the plant cell were clearly visible in the onion root cells under HPO?
Under high power objective (HPO) microscopy, the onion root cells typically display several clearly visible parts, including the cell wall, which provides structure and protection, and the large central vacuole that appears as a prominent clear space. The nucleus can also be observed, often stained and located near the cell wall. Additionally, the cytoplasm may be visible, containing various organelles, although details may vary based on the staining technique used.

What parts of a plant cell were clearly visible in the onion root cells focused under HPO?
Under high power objective (HPO) microscopy, several parts of the onion root cells are clearly visible, including the cell wall, which provides structure; the large central vacuole, which stores nutrients and waste; and the nucleus, often seen as a darker circular structure within the cell. Additionally, the cytoplasm can be observed, which contains various organelles. The overall rectangular shape of the cells is also evident due to the rigidity of the cell walls.
What parts of the cell were clearly visible in the onion root cells focused under hpo?
In onion root cells focused under high power magnification (hpo), the visible parts of the cell would include the nucleus, cell membrane, cytoplasm, and possibly cell walls. Depending on the specific staining technique or preparation method used, other organelles such as mitochondria, endoplasmic reticulum, and vacuoles may also be visible.
What parts of the onion cells are not found in the blood cells?
An onion cell has a cell wall and a large central vacuole, both of which are not present in mammalian blood cells. Additionally, onion cells have chloroplasts for photosynthesis, while blood cells do not contain chloroplasts.
How do the structures and arrangement of cells in an onion help to protect and support the parts underneath it?
The outermost layer of cells in an onion, the epidermis, forms a protective barrier against environmental stresses. The arrangement of cells in multiple layers allows for strength and flexibility, providing support to the parts underneath. Additionally, specialized cells called sclerenchyma cells provide extra structural support to the onion.
How does the arrangement of onion cells help support the parts underneath it?
provides protection from harm
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.

Where are onion cells found?
All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.
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 do you stain onion and cheek cells?
we stain onion and cheek cells for the following reasons: To prevent the cells from drying quickly To preserve them To disinfect them To make the organelles clearly visible By doing so you will get a clear picture on the microscope and dear reader also remember that you should always keep the cove slid carefully to avoid bubbles in the mount. Hope this piece of information has helped you. All the best

What cell parts did you find in the onion cell but not in the cheek cells?
The onion cells are much more rectangle shaped, than the cheek cells and the nucleus in the onion cell is much more bigger and better seen in the microscope.
Describe how the onion and cheek cell were different in observed parts what parts did they have in common?
The Onion cell and cheek cell both had cytoplasm, nucleuses, and cell membranes under 400x Magnification

Why do onion skin cells have no chloroplast?
because it is only found in green parts of plants
