Animal cells do not have cell walls (as in the case of plant cells). When they absorb too much water, they will not build up turgor pressure but lyse (burst). This is because there is no cell wall to oppose water from entering the animal cell.

How does water affect the appearance of a vegetable?
The amount of water in the cells of a vegetable affect the turgor pressure in the cells. The turgor pressure is how much pressure is in the cells. If the cells of the vegetable do not have enough water, the turgor pressure is low, so the plant wilts, making the vegetable look shriveled or small. If the cells of the vegetable have the right amount of water, the turgor pressure is high enough to keep the plant from wilting, so the vegetable looks healthy. If the cells of the vegetable have too much water, the turgor pressure is very high, and the cells may burst open, making the vegetable look shriveled and small.
What is a characteristic of cancer cells?
The most common characteristic of cancer cells is that they multiply rapidly. Cancer cells can multiply at a rapid pace and make the patient weak.
True or false guard cells control the opening and closing of the stomates?
Yup. Guard cells, shaped like little kidney beans, are arranged in pairs at a stomate, with their concave sides facing each other. These concave sides have a thicker cell wall than the remainder of each cell's wall, so that when water is driven in, the guard cells swell, causing the concavities to spread apart in the middle, opening an eye-shaped slit. This is the open stomate, which lets out gasses from respiration (namely O2, and often a characteristic fragrance, like Sweet Gum trees make the woods smell sweet) and water vapor. When the turgor pressure (or internal water pressure in each cell) subsides, the cells reduce in size, and the erstwhile separated concavities of the guard cells now fully touch, closing the stomate.
Who stated plant cells produce plant cells and animal cells produce animal cells?
i think that it was virchow? we learned it in science earlier this year!
What two basic types of cells make up all living things?
The two basic types of cells , I belive, are plant and animal cells.
Why arent animal cells capable of tugor pressure?
In a plant cell, the large central vacuole takes in the water and gives the turgor pressure in plant which allows it to stand up. The animal cells do not have this large central vacuole, and it is unable to maintain all the water and give the turgor pressure.
What is it called when animal cells burst?
When animal cells burst it's called lysis.
Can plant cells have negative turgar pressure values?
Plant cells are not known to have negative turgor pressure values. However, there are times when plants will have low turgor pressures which may result into negative turgor pressure values.

What helps a plant cell maintain turgor pressure?
That would be the large central vacuole. In plant, not only does it contain water, it also controls turgor for when the plant receives a lot of water instead of simply lysing like in animal cells.
The pressure that builds in a plant cell as a result of osmosis is called?
The pressure that builds in a plant cell as a result of osmosis is called turgor pressure.
What are cells with low internal water pressure called?
Turgor
What is the function of the animal cell wall?
By definition, animal cells have no cell wall -- only plant cells do. That being said, the major function of the cell wall in plant cells is to control cell pressure due to the influx and exit of water into and out of the cell. Turgor in the plant cell is part of what gives a plant structure and helps it "stand up." Animal cells do not need this characteristic, as they have other mechanisms for maintaining structure and shape.
Turgor pressure occurs in what kind of solution?
Turgor pressure is usually calculated as the difference between water potential and osmotic potential. In herbaceous plants turgor pressure is almost solely responsible for maintaining an erect habit. Wilting of leaves is due to loss of turgor in the leaf.
When do plants exhibit turgor pressure?
When the vacuole of plant cells absorb too much water, it swells so big, that it squashes the cytoplasm, and begins to exert pressure on the cell wall. This pressure is known as turgor pressure.
The internal pressure of a plant cell is called what?
turgor pressure, also turgidity, is the main pressure exerted by cell contents against the cell walls in plant cells
Importance of osmoregulation for body cells?
Please see: Turgor pressure. Thank you
