What else can I help you with?
Did you observed any change in the image of onion cells before and after starring?
In cooking, the onion would caramelize.
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.
Where can you find onion epidermal cells?
Onion epidermal cells can be found on the outer layer of an onion bulb, specifically in the thin, transparent skin that covers the onion. This layer serves as a protective barrier for the bulb and is often used in biology labs for microscopic studies due to its easy accessibility and clear cell structure. To observe these cells, you can peel off a small section of the onion's skin and place it on a microscope slide.
Why do you not observe chloroplast in the onion epdermis?
Onion are under the soil.So they do not get sunlight for photosynthesis
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.
Did you observe any change in the image of the onion cells before and after?
its look like a tissue paper

How do scientist examine the tip of an onion root?
Scientists can examine the tip of an onion root by preparing a thin section with a microtome and staining it to make the cells visible under a microscope. They can then observe the different cell types in the root tip, such as root cap cells, meristematic cells, and elongating cells. This allows them to study the process of cell division and growth in the root tissue.
Where can you find onion epidermal cells and what is their significance in plant biology?
Onion epidermal cells can be found in the thin, transparent layer on the surface of an onion bulb. These cells are significant in plant biology because they are commonly used in science experiments to study cell structure, division, and function. They are also used to observe processes such as osmosis and plasmolysis.
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.
How did iodine solution affects the image of the onion cells?
Iodine solution stains the starch granules in the onion cells, making them appear darker under a microscope. This helps visualize the structure and distribution of the starch granules within the cells, providing information about the cellular organization of the onion tissue.
What is the structure and function of onion cells labeled in a microscopic image?
The structure of onion cells consists of a cell wall, cell membrane, cytoplasm, and a large central vacuole. The function of these cells is to provide support and protection to the plant, store nutrients, and regulate water balance.
How did the iodine solution affect the image of the of onion cells?
there will be change in the color for iodine into blue,black because of the presence of starch in it.
