Those that you can see under the microscope are the cell wall, nucleus, nucleolus, and cytoplasm.
What else can I help you with?
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.
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.
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.
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 do onion skin cells have no chloroplast?
because it is only found in green parts of plants
What parts of the onion cells can identify?
nucleus, cytoplasm and cell membrane, and cell wall
Describe how the onion and cheek cell were similar in observed parts what parts did they have common?
Describe how the onion and cheek cell were similar in observed parts what parts did they have common? Well they are similar because they both have a nucleus and cytoplasm. They are different because in an onion cell there is a cell wall, doesnt have chlorplast, and it is a plant. For a cheek cell it has a cell membrane, doesnt have a cell wall, and is an animal.
Which parts of the onion cells stood out the most after they were stained?
Only you know that because you did the experiment not us.
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.
What effect did staining the onion cells have on their appearance under the microscope?
Staining the onion cells allowed for better visualization of the cell structures. It added color to the cells, making them more distinct and easier to observe under the microscope. This made it easier to identify the different parts of the cells, such as the nucleus and cell wall.
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.
