How stomata reacts with water?
When light hits the stomata it activates photosynthetic K+ pumps. These cells pump potassium ions into the guards cell around the stomata. Water is attracted to the potassium ions and thus enters the guards cells. This causes the guard cells to swell, but the rigidity of the one side causes that side to bow inwards, this creates an opening for gases to exchange in the leaf. This opening is the stomata. When water is not present, the stomata will not open.

What happens to stomata in saline solution?
The stomata are closed when exposed to saline solution or salt water. If a plant is exposed to the salty water it will become dehydrated and eventually die. Uness the plant is a type of mangrove or is salinity tolerant plant.
What do guard cells regulate?
The Guard cells control the openings of the stoma in plants. When light hits the guard cells, it caused the cell to pump potassium ions into the guard cells. As potassium is pumped into the guard cell, the water potential decreases. This drop in water potential causes the water from the intercellular spaces and surrounding cells to enter the guard cell increasing the turgidity and opening the stoma. The loss of potassium, and the increase in the relative water potential closes the stoma as the guard cell as they return to a flaccid state.
What is the role of guard cells do in the leaf?
Guard cells change shape to open and close stomata. When they are flaccid, the stoma is closed. When they are full of water and firm, the stoma is open. There are 2 guard cells controlling a stoma. Water enters guard cells by osmosis and they change shape.
What is the link between potassium and guard cells?
K+ is important in openin of stomata.Increasing of k+ concentration opens the stomata.
What is the legal definitionof guard dog?
A guard dog guards everything behind your fence or in your house, a protection dog will protect you outside your property, a watch dog will give alarm when someone enters your property. A rottweiler is an ideal guard dog.
What mechanism causes stomates to open when the guard cells are in good conditions?
The reversible uptake and loss of potassium ions (K+)
What happens when stomata opens?
Carbon dioxide, Oxygen, water vapor, and other gases enter and exit the stoma. They open during the day because plants need to take in raw materials (Such as the three listed at the beginning of the answer) to make food.
How does stomata open?
The stomata's function is to allow gas exchange with the surrounding air, so that the plant can intake carbon dioxide and oxygen. Stomatal opening is favored when there is plentiful water and moderate temperatures. Abscissic acid, a plant hormone, acts on the guard cells to open and close stomata. Some plants are even genetically engineered with a mutated era gene, which makes them more sensitive to abscissic acid and more prone to the opening and closing of guard cells. When guard cells are full of water, they stretch away from each other and the stomata are open. When guard cells are limp, they fall on each other and the stomata are closed. Potassium ions play a role in the opening and closing of stomata by changing the concentration of ions in the guard cells. When the potassium ions are in the guard cells, water also flows in the guard cells because of osmosis and the stomata open. When the potassium ions are out of the guard cells, water also flows out of the guard cells because of osmosis and the stomata close.
What should a security guard do if a person enters a building and flashed an ID card while walking past to an elevator?
Demand him to halt. Verify his business and destination.
Does water enters the plant through stomata?
The cells that regulate how much air and water pass through the stomata are called guard cells.
Why plants need potassium ions?
Plants need Potassium because Potassium helps determine the anion-cation balance in cells and is involved in protein synthesis, opening and closing of stomata, activation of enzymes and maintainence of turgidity of cells.If potassium is not enough, it leads to scorched leaf tips, shorter internodes, dieback chlorosis in inter-veinal areas, loss of apical dominance, bushy habit, loss of cambial activity, plastid disintegration and increase in rate of respiration.I hope that helps.:)
