It is the foundation of almost any organism's biochemistry

Explanation:

Osmosis, as you know, is the movement of water from a high to a low concentration. This is vital in the osmoregulation of plants and it is imperative for preserving water when needed, as well as excreting excess water.

There are endless examples, but I will just give you two, which are from different areas of biology:

  1. Human/animal Physiology - Your body filters your blood constantly, however, due to the small size of water molecules, a lot of water is filtered out of your blood, causing dehydration. So that you do not have to constantly drink, the filtrate (which will eventually become urine) will be dehydrated, and the water will be recycled into your body. This occurs due to osmosis.

  2. Plant Biology - Plants absorb water, by actively transporting polar nutrients into the roots. As a result, there is a high concentration of solute in the roots, which has to be equalized via osmosis. Hence, the nutrients persuade water to enter the roots
