20.2: Biogeochemical Cycles
A significant percentage of water evaporates immediately from the surfaces of plants. What is left reaches the soil and begins to move down. ... Carbon dioxide (CO 2) from the atmosphere dissolves in water and, unlike oxygen and nitrogen gas, reacts with water molecules to form ionic compounds. Some of these ions combine with calcium ions in ...

Hypoxic Respiratory Metabolism in Plants: Reorchestration of Nitrogen
Plants, as opposed to animals, are not equipped with a tissue or a system dedicated to oxygen (O 2) uptake and delivery to the organs.As a consequence, even under aerobic conditions, dense cell packing in some tissues may lead to permanent oxygen shortage, e.g. in developing and germinating seeds, tubers, bulky fruits, meristems, …

What is nature doing with all that nitrogen?
Credit: Joshua Stevens/NASA Earth Observatory. Nitrogen compounds have important roles in biology, including lowering blood pressure, helping relay signals in our bodies and providing nourishment for plants. In fact, industrially made fertilizers rich in nitrogen have effectively doubled the world's food-growing capacity.
