Are chloroplasts visible in onion and cheek cells?
No chloroplasts in cheek and onion cells
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 is the hypothesis of onion cell?
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.
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 are 2 organelles not visible in onion cell?
Two organelles not visible in an onion cell are the centrioles and lysosomes. Centrioles are involved in cell division and are not present in plant cells like onion cells. Lysosomes are membrane-bound organelles that contain digestive enzymes and are more commonly found in animal cells.

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.

Stain name used for onion cells?
safranine stain is used to stain onion cells
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.
Which stain you should use to stain onion peel?
To stain onion peel cells, you should use a stain called iodine. Iodine is commonly used to stain cells because it binds to starches and glycogen in the cells, making the cells more visible under a microscope.
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.
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
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.
