Organisms without cell walls, such as animal cells, maintain their shape and prevent bursting through the regulation of osmotic pressure. They achieve this by using a flexible plasma membrane that can adjust to changes in the surrounding environment. Additionally, they utilize mechanisms like the sodium-potassium pump to manage ion concentrations and maintain osmotic balance, as well as structures like the cytoskeleton to provide internal support. These adaptations help them withstand osmotic changes and prevent lysis.
Unicellular organisms without cell walls can avoid bursting by regulating the movement of water across their cell membrane through processes like osmoregulation. They maintain an internal osmotic balance by adjusting the concentration of solutes inside the cell or expelling excess water. Additionally, some unicellular organisms have contractile vacuoles that actively pump out excess water to prevent bursting.
Cell walls permit the cells of plants, fungi, and bacteria to withstand very dilute (hypo tonic) external media without bursting. # . :)
Plants and fungi have cell walls. Note that while plants have cell walls made of cellulose, fungi cell walls are made of chitin.
Onion cells, like other plant cells, have cell walls to provide structural support and protection. The cell wall is made of cellulose fibers that help maintain the shape of the cell and protect it from damage. Without cell walls, onion cells would be more fragile and prone to bursting.
The species inside the animal kingdom are example organisms that do not have cell walls. This includes reptiles, birds and mammals.

Animalia
The species inside the animal kingdom are example organisms that do not have cell walls. This includes reptiles, birds and mammals.
Plant and bacterial cells have cell walls that provide structural support and protect them from bursting in a very dilute solution. The cell wall helps maintain the shape of the cell and prevents excessive water uptake through osmosis. Additionally, bacteria often have mechanisms to actively regulate their internal osmotic conditions to prevent bursting.
As far as I have learned Eukaryotic cells, specifically Animals cells are the only organisms without cells walls. Fungi have cell walls and they are made of polysaccharide Chitin, the subunit of which is glucosamine(C8H13O5N).
Yes, different organisms have different substances in their cell walls. For example, plants have cell walls made of cellulose, fungi have cell walls made of chitin, and bacteria have cell walls made of peptidoglycan. These differences in cell wall composition are important for distinguishing between different types of organisms.
Bacteria with peptidoglycan cell walls and fungi with chitin cell walls are two examples of single celled organisms with cell walls.
only plants have cell walls, so all plants would be the answer.
Cell walls play an important part in maintaining rigidity and supporting structure. For example, if large amounts of water enter the cell, the cell wall prevents it from bursting. This is why animal cell, that lack a cell wall, will burst in this situation.
