Guard cells become curved when water pressure within them increases, causing them to swell. This swelling occurs due to osmosis, where water enters the guard cells, resulting in turgor pressure that forces them to bend. As the guard cells curve outward, they open the stomata, allowing gas exchange for photosynthesis and transpiration to occur. Conversely, when water pressure decreases, the guard cells become flaccid and the stomata close.

Fluids and small solutes are forced between cells of the vascular endothelium due to .?
Fluids and small solutes are forced between cells of the vascular endothelium due to hydrostatic pressure, which pushes fluid out of the capillaries into the surrounding tissues. This process is influenced by the balance of osmotic pressure, where proteins in the blood draw fluid back into the vessels. The combination of these pressure gradients facilitates the exchange of nutrients and waste products between the blood and tissues.
How will epithelial cells behave when placed in a hypo-tonic solution?
When epithelial cells are placed in a hypotonic solution, water will enter the cells due to osmosis, as the concentration of solutes inside the cells is higher than that of the surrounding solution. This influx of water causes the cells to swell and may lead to cytolysis if the osmotic pressure becomes too great. Ultimately, the cells may become turgid, and in some cases, they may burst if the pressure exceeds their structural limits.
What is an example of tugor pressure?
Turgid pressure is the outward pressure that happens in a plant cell when the vacuoles and cytoplasm fill up with water. It pushes the plasma membrane against the cell wall of bacteria, plant, and fungi cells.
When water moves into a plant cell by osmosis the internal turgor pressure developed pushes on the wall. What does this do to your understanding of a neglected house plant?
If a neglected house plant does not receive enough water, it can lead to a decrease in turgor pressure within the plant cells. This can cause the plant to wilt as it loses structural support and becomes dehydrated. Regular watering helps maintain turgor pressure and keeps the plant healthy.
Blood plasma becomes tissue fluid by the process of?
By the process of ultra-filtration. At the proximal end of the capillary, you have pressure of about 30 mm of mercury. So the fluid leaves the capillary and enter the interstitial compartment. At the distal end of the capillary the pressure is about 15 mm of Mercury. The fluid in drawn in due to oncotic pressure at that end.
What is it called when animal cells burst?
When animal cells burst it's called lysis.
What is the fluid that is forced out of the capillary beds by hydrostatic and osmotic pressure into the tissue spaces called?
The fluid that is forced out of the capillary beds into the tissue spaces by hydrostatic and osmotic pressure is called interstitial fluid. This fluid surrounds the cells in tissues and is essential for nutrient and waste exchange between blood and cells. It is a key component of the extracellular fluid compartment in the body.

Thunderstorms develop as a result of which process in ocean areas?
rising warm air creating low pressure cells rising warm air creating high pressure cells falling air temperatures creating low pressure cells falling air temperatures creating high pressure cells
What happens druring mitosis?
Mitosis is the division of cells. It's when one cell becomes two, and two becomes four cells. Mitosis only occurs with body cells, not gametes/sex cells.
Why is blood at its highest pressure when it leaves the heart?
Because pressure is built up in the left ventricle of the heart before it is forced out through the aorta in order for blood to be forced around to the body efficiently to the cells where it is needed. Without this high pressure, blood would not be efficiently ejected to the body and it can pool in the ventricles, which can cause problems. This high pressure in the ventricle is also required in order for blood to travel around the body. This is because blood moves from an area of high pressure to low pressure to travel. This same principle is used for cells to gain oxygen and other necessities. For example, oxygen will diffuse from the capillaries (smallest blood vessels) which has a high concentration of oxygen into cells, which have a low concentration of oxygen. Hope this helps ! :)
Why did plant cells plasmolyze when immersed in a hypertonic solution?
Plant cells plasmolyze when immersed in a hypertonic solution when the cell wall detaches under high pressure causing water to be lost. The more solutes a cell has, the less water becomes available.
Organizations or communities of cells are called?
complied cells can be called tissues which can then becomes organs
What part of a flower becomes the seed when sperm cells fertilize the egg cells?
The ovary
