What else can I help you with?
What plant organelle is missing from the onion cell?
The onion cell is missing chloroplasts, the organelles responsible for photosynthesis in green plants. Onion cells do not contain chlorophyll, so they do not require chloroplasts for photosynthetic processes.
What structure you seen in hydrilla leaf cell but in onion cell?
The structures that are found in the hydrilla which are not found in the onion cell are chloroplasts, specifically the stomata and chlorophyll. Onions lack these structures because they grow underground.
What Onion epidermis is a suitable tissue to use for observing cellular structures with a compound light microscope because this tissue is thin enough to?
Onion epidermis is a suitable tissue for observing cellular structures with a compound light microscope because it is transparent, allowing light to pass through easily, and the cells are thin enough to view individual cells and structures such as cell walls, nuclei, and chloroplasts. Additionally, the large size of onion cells compared to other plant cells makes it easier to study their internal structures.
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.
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.
Why are no chloroplasts fond in the onion cells?
Onions are underground structures. They do not get sunlight.
What plant organelle is missing from the onion cell?
The onion cell is missing chloroplasts, the organelles responsible for photosynthesis in green plants. Onion cells do not contain chlorophyll, so they do not require chloroplasts for photosynthetic processes.

The structures that are found in the hydrilla which are not found in the onion cell are chloroplasts, specifically the stomata and chlorophyll. Onions lack these structures because they grow underground.
How do the cells of the onion compare with those of the cells you have seen before?
Onion cells are typically rectangular and have a clear, defined cell wall, which provides structure and rigidity. Unlike animal cells, they contain a large central vacuole that helps maintain turgor pressure, and their cytoplasm appears less dense due to the presence of this vacuole. Additionally, onion cells often show a distinct nucleus and are organized in layers, which can be contrasted with more irregularly shaped cells seen in other organisms. Overall, onion cells exemplify the characteristics of plant cells, showcasing differences from the more varied shapes and structures of animal cells.

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.
What is the difference between frog cell and onion cell?
Oh, dude, it's like comparing apples and oranges... or in this case, frogs and onions. Frog cells come from frogs, obviously, and onion cells come from onions. They have different structures and functions, but hey, at the end of the day, they're both just cells, man.

The markers help to highlight and distinguish these structures, allowing for a more detailed and precise analysis of the onion cells.
Stain name used for onion cells?
safranine stain is used to stain onion cells
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 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.
