FRAGMENT FROM NATURE these next two weekends deal with plants as alien creatures with confoundingly complex life styles, such as alternation of generations. Plants asexually make spores, which are single haploid cells (one set of chromosomes, n) that can make another plant when stuck in the ground. They also use sperm and egg to reproduce. But the two are linked: the sexual plant makes an asexual plant (n), and that in turn completes the cycle by making the sexual plant (2n), and each event makes a new generation, by alternating sexual and asexual reproduction. Weird.
