Diatoms – Microscopic single-celled algae.
 
Being a component of the ocean plant plankton, diatoms are microscopic single-celled algae. The cell wall of these organisms is made of hard silica (precious opal, by the way), and forms a kind of box with a bottom and a lid. During reproduction by division, the new diatom takes part of the “parent” shell with it and adds a smaller bottom to it. This causes subsequent generations of these algae to become smaller and smaller.

However, this process does not last indefinitely. When the minimum size limit is exceeded, the genital unarmored generation (the so-called auxospore) generally appears in the sea. Which has the ability to grow unhindered – and then the cycle begins again… 25 We owe the percentage of oxygen in the Earth’s atmosphere to diatoms, which produce it in the process of photosynthesis. They also make up a quarter of the biomass found in all seas and oceans.
