What is pearling?

Pearling is the common term given to the visible production of oxygen bubbles on aquarium plant leaves.

It's a desirable process that many planted aquarium owners strive for, indicating that the plants are photosynthesising and growing sufficiently in order to saturate the water with enough oxygen. Once the water is saturated the oxygen produced from the plant visible appears as attractive bubbles formed on the plant leaves.

My tanks used to do that when I was a kid.
