Bacteroid A modified bacterial cell in a root nodule, typically a cell of the bacterium Rhizobium in the root nudule of a leguminous plant (family Fabaceae).
But in places with lots of life, rain-making particles are often biological in origin, like bacteria, pollen, plant fragments, and spores from mushrooms.
For every 10 medications used by humans, 7 contain chemical compounds that originally came from the natural world, mostly from bacteria, fungi, and plants.
But those species are themselves part of a complex ecological web that can't be sustained without a much greater diversity of animals, plants and bacteria.
