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 else can I help you with?
Leaf Cell's use chlorophyll to absorb what?
Light
How is an onion cell specialised?
An onion cell is specialized for storage of nutrients. It has a large central vacuole that stores water and other molecules, while the cell wall provides structure and support. The outermost layer of the onion cell is specialized for protection against pathogens and physical damage.
Which part of a plant cell will you never find in a onion bulb?
As an onion cell is a cell, no cells are located in it, but maybe you mean organelles, which literally mean "tiny organs" and make up every cell. In that case, onion cells lack chloroplasts because they grow underground and therefore don't use the sun to produce energy (chloroplasts are involved in photosynthesis).
What can you use to look more closely at a whole leaf?
You could use a magnifying glass or a microscope to get a closer look at the details of a whole leaf, such as its veins, stomata, and cell structure.
Why do we use NaCl in a plasmolysis of onion?
NaCl is used in plasmolysis of onion cells to create a hypertonic solution, causing water to move out of the cell and shrink the cell contents away from the cell wall. This helps in studying the structure of the cell membrane and cell wall under different conditions.
What is a onion cloute?
onion cloute is an onion cut in half. take one half and pin a bay leaf to it using whole cloves. i use four cloves. it is then put into the milk for a bechamel sauce.
Leaf Cell's use chlorophyll to absorb what?
Light
What is leaf cell in VLSI?
In standard-cell based design, leaf cells are already pre-designed and stored in a library for logic design use.
How is an onion cell specialised?
An onion cell is specialized for storage of nutrients. It has a large central vacuole that stores water and other molecules, while the cell wall provides structure and support. The outermost layer of the onion cell is specialized for protection against pathogens and physical damage.
How do you tell how much the onion cells are magnified?
An onion cell has a rectangular shape and its size can range in length from 0.25 to 0.4 millimeters. If you take a picture of the magnified onion cell and measure its diameter in millimeters then you can use simple maths to determine how much magnification is being applied.
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.
Which part of a plant cell will you never find in a onion bulb?
As an onion cell is a cell, no cells are located in it, but maybe you mean organelles, which literally mean "tiny organs" and make up every cell. In that case, onion cells lack chloroplasts because they grow underground and therefore don't use the sun to produce energy (chloroplasts are involved in photosynthesis).
What sampling method would you use to find small animals in leaf litter ir soil sample?
sweep net
Why do you use iodine solution during the preparation of slide of onion peel?
Iodine solution is used to stain the cell contents in the prepared slide of onion peel. This helps highlight the cell structures and makes it easier to observe under a microscope, such as the nucleus and cytoplasm of the onion cells.
What can you use to look more closely at a whole leaf?
You could use a magnifying glass or a microscope to get a closer look at the details of a whole leaf, such as its veins, stomata, and cell structure.
Why cant you use a oak leaf under a microscope?
You can use an oak leaf under a microscope, but you wont see anything. Haha, the oak leaf is too thick to be able to see the cells, and obviously what in inside of the cell. If you want to see something under a microscope that is a plant cell, onion skin works well! Hope I helped!
Why you use iodine in onion?
Iodine stains the onion so it is easier to see the cellular features, such as the nucleus, cell wall, and cytoplasm.
