The guard cells in a plant are responsible for opening and closing the stomata. The stomata is a tiny opening on the blade of a leaf that allows for carbon dioxide to enter and water + oxygen to be released. The guard cells are triggered by concentrations of potassium ions.

Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata

What swell in pull open the stomata so the plant can breath?
The guard cells.
What are 3 types of plant cells?
epidermal cells,guard cells and onion cells
Why are cutin stomata and guard cells absent in elodea?
Cutin, stomata and guard cells are used for water loss prevention. These are not needed because Elodea is a water plant.
What cell contains chlorophyll?
Guard cells and mesophyll thats all i remember
What is the difference between a human nerve cell and plant guard cell?
Human nerve cells allows information from the brain to be carried to other parts of the body BUT plant guard cells allows the amount of oxygen to enter the stomata.
What swell in pull open the stomata so the plant can breath?
The guard cells.
Do all plants have guard cells?
yes all plants have guard cells because if there's a plant that don't have guard cells the stomatal pores will not open neither close
Why do you think the plant evolved to have guard cells?
for bad people
What surrounds the stoma of a plant?
Guard cells are what surround stomata.
Which types of cells contain chloroplasts?
The guard cells of stomata alone contains chloroplast.
What do guard cells close to prevent excess water loss?
The guard cells provide the plant with the control mechanisms. The guard cells control the opening and closing of the stomata in plant tissue. Without guard cells, the plants would not be able to control its water intake.
What are 3 types of plant cells?
epidermal cells,guard cells and onion cells
What is the guard cells in a plant cell?
The function of the guard cells are that they help to regulate the rate of transpiration by opening and closing the stomata thus preventing excessive water loss.
What are the holes in leaves surrounded by guard cells?
StomataThe holes in leaves surrounded by guard cells are called stomata. These stomata help regulate the water that goes into and out of the plant.
