Plant spores are haploid (having a single set of chromosomes in each cell) and are produced by the sporophyte, following meiosis; see alternation of generations. Bacterial (for example, anthrax) spores pose a threat because they may be resistant to common sterilization procedures, and because they could be treated to create powerful biological weapons.
