Plants require a source of fixed, or biologically reactive nitrogen (N) to produce molecules such as nucleotide bases and amino acids, in order to make macromolecules like DNA and proteins that are then required for the genome, cellular structures and overall growth. Low or insufficient available...
Birds do it. Bees do it. Plants do it, too. And for good reason: Sexual reproduction has evolved as nature's way of shuffling the genetic deck of cards, so to speak. That shuffling actually starts before organisms make sex cells (sperm and egg). In this process, called meiosis, matchi...
