This is considered false. Although the percentage of all air remains the exact same regardless of altitude, it all matters about the air pressure in the atmosphere. Even though the percentage would be the same, there would be fewer oxygen molecules at higher altitudes and lower pressure.
Answer:
D) K being transported out of the guard cell.
Explanation:
The movement of water in the terrestrial plants is a very important factor as each cell of the plant require water to survive.
The movement of water is influenced by many physical, chemical and process going on in the plants like transpiration and stomatal opening and closing.
Water posses adhesion and cohesion properties which allow the water molecules to form a bond with other surface and with each other respectively. This allows the movement of water in the xylem by a process called capillary action.
The evaporation of water creates a pressure on the plant to absorb water from the soil but when potassium ions move out of the guard cell of stomata, the guard cells lose turgidity and stomata gets closed.
Thus, Option-D is correct.
The carbon cycle illustrates the central importance of carbon in the biosphere. ... During this process, plants cleave the carbon from the two oxygen molecules and release the oxygen back into the surrounding environment. Plants are thus primarily responsible for the presence of atmospheric oxygen.
