When an onion cell is placed in a baking soda solution, which is basic, it can undergo changes in its osmotic balance. The high concentration of sodium bicarbonate may cause water to move out of the onion cells, leading to plasmolysis, where the cell membrane pulls away from the cell wall. As a result, the onion cells may appear shriveled and less turgid. The basic environment can also affect the cell's internal pH and potentially impact cellular processes.
In a hypotonic environment, an onion cell will fill up with water. Hypotonic refers to a solution that has lower osmotic pressure than the solution you're comparing it to.
it turns purple and under a microscope you can see swirlys
If an onion cell epidermis is placed in a hypertonic solution, water will move out of the cell due to osmosis, causing the cell to shrink and the cell membrane to pull away from the cell wall. This process is known as plasmolysis.
Nothing. The onion will get wet.
When a red onion cell is placed in a sucrose solution, water from inside the cell will move out due to osmosis. This will cause the cell to shrink and lose its turgidity as water moves from an area of higher concentration to lower concentration (from inside the cell to the solution outside).
they will disintegrate and soon the onion will peel and the onion part will BE NO MORE
To cut onion rings for frying or baking, first peel the onion and slice it into thick rings. Separate the rings and coat them in a batter or breadcrumbs. Then, fry in hot oil or bake in the oven until crispy and golden brown.
The onion is sprouting or trying to grow, if it were placed in the soil it would develop roots as well
This depends on the nature of the NaCl solution...If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".
The reason why an onion was placed in a mummies hand was for its strong smell to keep animals away.
What happens is the alcohol starts to shred the onion. Next alcohol is soaked up inside the onion which starts to make the onion shrink. The cell can't take the acid that goes in it shrinks and dissolves.
An Onion cell as a contractile vacuole. This allows the cells to remover more water especially when placed into a hypotonic solution. An epithelial skin cell of the cheek does not have a contractile vacuole. The acess water cannot be stored, therefore the cell bursts.
