It is widespread in the Old World and inhabits warm, stagnant, but not overly nutrient-rich waters in Europe, the Caucasus, parts of Africa, and Asia. In Germany, it is considered very rare.\u003cbr\u003e \u003cbr\u003eThese tiny plants are only a maximum of 1.5 mm in size (usually even less than 1 mm!) and very simple in structure. They have no roots, leaves, or other plant organs and essentially consist of just a small ball of cells in a floating cushion. They can also \u003ca href=\"https:\/\/www2.palomar.edu\/users\/warmstrong\/images2\/wobofl2c.jpg\"\u003eflower\u003c\/a\u003e . Their flowers consist of only a few cells, each forming a single style and a single stamen. \u003cem\u003eWolffia arrhiza\u003c\/em\u003e usually reproduces by budding rather than by seed. In this process, a second ball of cells grows from the mother plant, and the two separate after some time. For overwintering, they produce turions, which contain little chlorophyll but a lot of starch (hence the yellow color!). These sink to the bottom of the water body in winter to survive the cold season.\u003cbr\u003e \u003cbr\u003e\u003cem\u003eWolffia arrhiza\u003c\/em\u003e is mixotrophic. Besides photosynthesis, it can also directly obtain carbon from the surrounding water, which simply diffuses into the tiny plant. It is very nutrient-rich. When dried, it consists of approximately 40% protein and 40% starch.\u003cbr\u003e\u003cbr\u003e If you rub \u003cem\u003eWolffia arrhiza\u003c\/em\u003e between your fingers, you immediately notice that it is much harder than other duckweeds and feels like fine sand. This makes it very easy to distinguish from other small duckweed species.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e You will receive approximately 1-2 ml of plants in a 5 to 10 ml Eppendorf tube. This may sound like a small amount, but it's enough to cover a roughly 10 cm diameter dish with a layer of \u003cem\u003eWolffia\u003c\/em\u003e !
