Which type of plant cells open and close the stomata to adjust the flow of air and water into and out of the plant?
Gaurd cells
What is the relationship between guard cells and stomata?
Guard cells are cells on the edges of the stomata of a leaf. The stomata are very small pores that control water loss and keep the plant from drying out. When Abscisic Acid (ABA) - a stress hormone - is present, the Potassium ions (K+ ions) from the guard cells leave the guard cells for an unknown reason. This causes the stomata to close. Basically, guard cells assist stomata in opening/closing
Which structure is responsible for the opening and closing of stomata?
guard cells
What surrounds the stoma of a plant?
Guard cells are what surround stomata.
How might the plasma membrane of a plant cell change in response to the cold temperatures of winter?
The plant cells membrane will solidify and the stomata may close in order to hold the plants nutrients.
Which type of plant cells open and close the stomata to adjust the flow of air and water into and out of the plant?
Gaurd cells
What is the role of a stomata and guard cells?
Through the stomata carbon dioxide diffuses into the plant and oxygen and water vapor diffuse out of the plant. Guard cells control the opening and closing of the stomata. Used in arid climates to control water loss for instance.
How do substances for photosynthesis enter the plant?
Pores called stomata, which open and close by guard cells.
What is the plant responsible for limiting water loss?
Guard cells, which open and close stomata. Also, cutin.
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 helps the stomata open and close so that the plant doesnt dehydrate and die?
Turgidity and flacedness of guard cells

What cells allow the plant to transpire?
The stomata
Does water enters the plant through stomata?
The cells that regulate how much air and water pass through the stomata are called guard cells.
Which structure is responsible for the opening and closing of stomata?
guard cells
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.

Guard cells are what surround stomata.
