Detailed explanation-1: -Pressure potential is generally positive. If a pressure greater than the atmospheric pressure and is being applied to pure water or a solution, then its water potential increases which is then equivalent to pumping water from one place to the another.
Detailed explanation-2: -One atmospheric pressure at sea level is equal to 760 cm of Hg.
Detailed explanation-3: -Atmospheric pressure changes at different altitudes. Pressure is greatest at sea level and decreases with height. Air is heaviest at sea level because the air molecules are compressed by the weight of the air above them.
Detailed explanation-4: -Answer: a) Atmospheric pressure is defined as the pressure exerted by the air that surrounds us. It is caused due to the height of altitude and due to the density of air.
