Vinegar is an acid that will break down the cell wall of the, onion cell. This could potentially break down the entire cell itself. This is why the cell will appear to have holes in it.
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.
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.
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.
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).
The structure of an onion cell includes a cell wall, cell membrane, cytoplasm, nucleus, and vacuole. The function of an onion cell is to store nutrients, provide support, and regulate the movement of substances in and out of the cell.
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.
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 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.
The cell will lose water and shrivel.
The cell expands/gets bigger.
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.

the animal cell is in the animal and the onion cell is in the onion
Nothing. There would be no gradient between the cell and the solution.
