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.
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.
i think that it was virchow? we learned it in science earlier this year!
The two basic types of cells , I belive, are plant and animal cells.
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.
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.

Turgor pressure in plant cells is maintained by the uptake of water through osmosis and the presence of a cell wall that exerts pressure on the cell's membrane. The central vacuole also plays a key role in regulating turgor pressure by storing and releasing water as needed.
The pressure that builds in a plant cell as a result of osmosis is called turgor pressure. This pressure is important for maintaining the rigidity and shape of plant cells.
Yes, plant cells can have negative turgor pressure values when there is water loss through transpiration or when the cell loses water due to osmotic gradients. This can cause the cell to plasmolyze or shrink, resulting in negative turgor pressure.
turgor pressure, also turgidity, is the main pressure exerted by cell contents against the cell walls in plant cells
To revive a wilted plant, you can water it to replenish lost turgor pressure. When a plant lacks water, its cells lose turgor pressure, causing wilting. Watering the plant will allow the cells to take up water, regain turgor pressure, and become rigid again.
The pressure in plant cells that makes them firm is called turgor pressure. It results from the osmotic movement of water into the cell, causing the cell to swell and exert pressure against the cell wall. Turgor pressure is important for maintaining the structural integrity and rigidity of plant cells.
False. Crenation, plasmolysis, and hemolysis are all related to osmotic processes in cells, but turgor pressure is not directly equivalent to hemolysis. Turgor pressure is the pressure exerted by the fluid inside plant cells against the cell wall, while hemolysis refers to the bursting of red blood cells.
Both plant and animal cells have organelles. However, plant cells have additional organelles such as chloroplasts and large central vacuoles that are not present in animal cells. These organelles are essential for functions specific to plant cells, such as photosynthesis and maintaining turgor pressure.
Vacuoles are small in animal cells but large in plant cells. They play a role in maintaining turgor pressure in plant cells and storing water, ions, and nutrients. In animal cells, vacuoles are smaller and more specialized in function.
Guard cells in plant stomata open and close due to changes in turgor pressure. When the cells accumulate water and become turgid, they bow outwards and open the stomatal pore. Conversely, when water is lost and turgor pressure decreases, the guard cells become flaccid and close the pore.
