<span>Basically, guard cells are cells surrounding each stoma and they help to set the rate of transpiration by opening and closing the stomata. Some guard cells are turgid or swollen and the stomatal opening is large. Hence ths turgidity is caused by the accumulation of the potassium ions in the guard cells. Thus, when the potassium ions or K+ levels happen to increase in the guard cells the water potential of the guard cells drops and water enters the guard cells. Some guard cells have lost water which causes the cells to become flaccid and the stomatal opening to close. This may occur when the plant has lost an exessive amount of water. Moreover guard cells function are the stomatal closing and the stomatal opening of the plant.</span>

1.Where is there more atmospheric pressure, in New Orleans, at sea level, or Mt. Everest? Why? a. New Orleans, because pressure
sineoko [7]

Answer:

a. New Orleans, because pressure increases as you get deeper in the atmosphere and closer to the center of Earth

Explanation:  

  • Low altitudes: There is more atmospheric pressure in comparison with higher altitudes. When closer to the Earth core, the more pressure and temperature there is.
  • High Altitudes: As high increases, atmospheric pressure, and temperature, decreases, leading to a lower oxygen partial pressure in the environment.

At sea level, the atmosphere pressures the earth's surface with approximately 1-kilogram per square centimeter strength. This means that at sea level, there is one ton of air making pressure over us. But this air pressure decreases with altitude.  

At high level there is less air making pressure from above, and there is less gravity acting. Molecules are more separate from each other, and the density decreases.
