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.
Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
Can you observe any chloroplast in the onion cell using microscope?
No, you cannot observe chloroplasts in onion cells because onion cells do not contain chloroplasts. Onions belong to a group of plants known as monocots, which typically lack chloroplasts in their cells. Chloroplasts are mostly found in the cells of green plants that undergo photosynthesis.
What is a good substiute stainfor looking at onion root tips under a microscope?
A good substitute stain for looking at onion root tips under a microscope is iodine solution. This stain will help to visualize the cells more clearly by highlighting the cell walls and starch grains present in the root tips.
Why do you use the onion for cell sample and not the leaf?
An onion is easy to peel to 1 layer of cells, and with a light microscope you cant see the individual cells in a leaf. Also the cell obtained from the bulb of onion is colorless, hence it can be easly stained with different dyes to study the cell organells under the microscope.
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 shape are onion cells?
Like a misshaped box. It is grey under a microscope.
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.
Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
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.
What details can be observed when an onion slide is placed under a microscope?
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 parts of the onion cells?
Those that you can see under the microscope are the cell wall, nucleus, nucleolus, and cytoplasm.
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.
Can you observe any chloroplast in the onion cell using microscope?
No, you cannot observe chloroplasts in onion cells because onion cells do not contain chloroplasts. Onions belong to a group of plants known as monocots, which typically lack chloroplasts in their cells. Chloroplasts are mostly found in the cells of green plants that undergo photosynthesis.
What is a good substiute stainfor looking at onion root tips under a microscope?
A good substitute stain for looking at onion root tips under a microscope is iodine solution. This stain will help to visualize the cells more clearly by highlighting the cell walls and starch grains present in the root tips.
How do cells of the onion specimen appear under the microscope?
Cells of an onion specimen appear rectangular or square in shape, with distinct cell walls forming the outer boundary. These cells also contain a large central vacuole that may appear as a clear, empty space in the center of the cell under the microscope. The cells are tightly packed together in a regular pattern, creating a characteristic appearance when viewed at high magnification.
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.
