This year's March 22 is the 23rd World Water Day, a seemingly clear drop of water, which is also very lively and there is a different world. If you put water droplets under a microscope, grasshoppers, amoeba, eye worms, algae, and all kinds of microorganisms may surprise you. Common single-celled organisms in water Common microorganisms in water include bacteria, actinomycetes, cyanobacteria, yeasts, molds, algae, viruses, protozoa, protozoa, protozoa and other nine types of organisms. Their structure is very simple, a cell or differentiated into a simple group of cells, that is, an organism that can live independently and assume all the functions of life activities. Although they are small, the entire surface of the body has the function of absorbing nutrients, which makes them have a particularly large appetite, if the sugar consumed by a bacterium in an hour is converted into a grain that a person wants to eat, then the person has to eat for five hundred years. Microorganisms not only eat a large amount and eat everything, organic matter, inorganic matter and even the latest synthetic complex organic molecules may be eaten by microorganisms. Microorganisms can multiply extremely quickly, and if it were not for the stranglehold of the environment and food, the total number of offspring produced by one bacteria in a 24-hour period would be equivalent to the weight of 4 earths. Therefore, this invisible world also has a decisive impact on our lives. Cao Qiang/Wen

Amoeba (200-400 microns) The amoeba is a full-fledged predator that can swallow grasshoppers that are several times larger than their body size by deforming. Amoeba can complete the reproduction of one to two and two to four through the division of cells.
Grasshopper (180-280 microns) Grasshopper is the most common microbial species in water, its shape is like a straw shoe, it has only one cell, but it can complete digestion, breathing, excretion, reproduction and other life activities, and has a certain purification effect on sewage.
Diatom (10-100 micron) Diatom cells are formed from the upper and lower shells, and the shell surface has obvious patterns. It is often connected by several or many individual cells into a variety of populations.
Hornworms (0.2-3 mm) Hornworms are shaped like trumpets, their bodies can take on a variety of colors, and their uniform cilia all over their bodies help them move freely. Trumpetworms can multiply by cell division or combine to reproduce.
Grenade worm (80-120 microns) The body of the grenade worm resembles an old-fashioned hand grenade, and there are many rows of membranous plates secreted by protoplasm outside the body, which surround the body and the cilia protrude from the gap between the plates.
Algae (1-2 mm) The algae dies in a spherical group of 1000-3000 similar cells, each with two flagellar on it.
Grand Theft Auto (10-30 microns) The Grand Theft Auto is conical or pear-shaped, with 5-7 rows of longitudinal stripes on its surface. The posterior part is thin, the end is flat, and the cilia are tufted, often with a sticky filament, from which they are born.
Eye worms (about 6 microns) Eye worms have long, fusiform or cylindrical bodies. A flagella sticking out of the notch in front of the body keeps them moving freely. The chloroplasts in the body can perform photosynthesis and are also their food factories. Eye worms can often turn water green.
Cryptoalgae (10-50 microns) Single-celled cryptoalgae are asymmetrical, with two flagella in the broader anterior segment that are able to move freely. There are no starch grains in the cell body, and there is a translucent cell wall on the surface of the body. Cryptoalgae vary greatly in color, with a variety of colors such as yellow-green, yellow-brown, blue-green, and red.
Gravis (30-100 microns) Gravis cells are diverse, with spherical, triangular, quadrangular and so on. Plant bodies are often composed of 2n cells, and the most discovered phytoidal algae is composed of 128 cells, which form a certain shape by their bulging connections on the cell wall.
