Onion cells do not burst like red blood cells because they have a rigid cell wall that provides structural support and prevents them from bursting under pressure. In contrast, red blood cells lack a cell wall and are more flexible, making them susceptible to lysis when placed in hypotonic solutions where water influx can cause them to swell and burst. Additionally, the osmotic balance in onion cells helps maintain their integrity.
What else can I help you with?
What is the outcome of placing a red blood cell and an onion cell in hypo-tonic solution?
both the cell will swell and rbc will burst easily while cells of onion peal will resist the bursting to some extenct
What parts of the onion cells are not found in the blood cells?
An onion cell has a cell wall and a large central vacuole, both of which are not present in mammalian blood cells. Additionally, onion cells have chloroplasts for photosynthesis, while blood cells do not contain chloroplasts.
What cells are in an onion tip but not the onion?
The cells in an onion tip but not the onion itself are usually actively dividing cells located at the growing tip of the onion root, known as the root cap cells. These cells help protect the delicate meristematic cells responsible for root growth and can often be found in the root zone of plants.
What is the effect of saltwater on onion cells?
If the concentration of salt is higher OUTSIDE the cell, then water will move from the cell to the outside (osmosis) to equilibrate the concentration gradient that you have created! Water will leave the cell, and the cell will shrink (due to the decrease in volume).
Are chloroplasts visible in onion and cheek cells?
No chloroplasts in cheek and onion cells

Are blood and onion cells filled with living material or are they empty?
They are both filled with living material.

Is it bad to eat raw onions?
Onions can be toxic to dogs. Dogs affected by onion toxicity will develop haemolytic anaemia, where the dog's red blood cells burst while circulating in its body. At first, pets affected by onion poisoning show gastroenteritis with vomiting and diarrhea. They will show no interest in food and will be dull and weak. The red pigment from the burst blood cells appears in an affected animal's urine and it becomes breathless. The breathlessness occurs because the red blood cells that carry oxygen through the body are reduced in number. The poisoning occurs a few days after the pet has eaten the onion. All forms of onion can be a problem including dehydrated onions, raw onions, cooked onions and table scraps containing cooked onions. Onion poisoning can occur with a single ingestion of large quantities or with repeated meals containing small amounts of onion. The condition improves once the dog is prevented from eating any further onion
What happens to purple onion skin cells when tap water is added?
When tap water is added to purple onion skin cells, the cells will undergo osmosis. Water will move into the cells, causing them to swell and potentially burst if too much water is absorbed. The purple color of onion cells may also diffuse into the surrounding water.
What is the effect of saltwater on onion cells?
If the concentration of salt is higher OUTSIDE the cell, then water will move from the cell to the outside (osmosis) to equilibrate the concentration gradient that you have created! Water will leave the cell, and the cell will shrink (due to the decrease in volume).
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.
Are chloroplasts visible in onion and cheek cells?
No chloroplasts in cheek and onion cells
Which of the 2 cells cheek or onion cells have a regular arrangement and structure?
Between the 2 cells that are cheek and onion cells, the one that has a regular arrangement and structure are onion cells. Cheek cells have an irregular shape.
Why do onion cells do not have chloroplast?
Onion cells do not have chloroplasts because the onion is underground where there is no light. Without light chloroplasts have no purpose, so onion cells just don't have them.
How do onion cells compare with whitefish cells in size?
A onion cell is : 0.2 mm
