Aldosterone
Explanation:
Mineralocorticoids are a group of hormones that act in the metabolism of minerals, mainly in the control of sodium and potassium ions. The major mineralocorticoid, responsible for at least 95% of the adrenal mineralocorticoid function, is the aldosterone hormone.
Aldosterone is a hormone that is produced in the adrenal cortex and is important for the control of blood pressure. It allows good blood pressure to be maintained and regulates the water and salt balance in the body by excreting sodium and potassium to inhibit the kidneys.

There are millions of spores produced by a single plant so that the chances of their dispersal and maturing into new plants is maximum.
Spores also have the capability to stay dormant until the conditions become favorable for the growth of a plant from the spore.
Another adaptation of spores is that they are light weight so that they can easily be carried away by the wind.
