and Love, the thirteenth day of the series.

Once upon a time there was a primitive single-celled organism called Amoeba that reproduced through mitosis. Amoeba was a simple organism, but it was not aware of its simplicity. It lived its life in the primordial soup, where it fed on organic compounds and multiplied through the processes of interphase and mitosis.

One day, while moving through the primordial soup, Amoeba encountered another single-celled organism named Euglena. Euglena was different from the other single-celled creatures Amoeba had encountered. She had a beautiful green color, which was caused by chlorophyll, and moved through the primordial soup with elegance thanks to her cilie. Amoeba immediately fell in love with her.

He began following Euglena everywhere she went, and they began communicating with each other through chemical signals. Together they began to work together and share nutrients, such as glucose (C6H12O6) and ammonia (NH3), and protection against hazardous substances in the primordial soup. This interaction was an example of symbiosis, with both organisms benefiting from the interaction.

Amoeba realized he didn't want to be alone anymore and asked Euglena if she wanted to live together and have children together. Euglena had also fallen in love with Amoeba and she agreed. Together they began to multiply via conjugation, a process by which two single-celled organisms unite and create a new cell with genetic variation. This created new types of single-celled organisms, with unique properties from both parents.

This multiplication via conjugation was an important step in the evolution of life on Earth. It led to the diversity of life we know today, with organisms adapting to the environment and continuing to develop. Amoeba and Euglena are the founders of the multicellular organisms we know today. Their love was the source of a great adventure, which led to the diversity of life on Earth that we know today.
