Check lists for individual taxa that live here, e.g. A biologist recorded a count of 499 bacteria present in a culture after 10 minutes and 857 bacteria present after 20 minutes. The spike moss Selaginella is a heterosporous lycophyte. Leaves capture more sunlight with their increased surface area by employing more chloroplasts to trap light energy and convert it to chemical energy, which is then used to fix atmospheric carbon dioxide into carbohydrates. Megaphylls are seen in ferns and more derived vascular plants. Of the people who have never been infected, 35% will become infected each year. This includes annual and perennial types. The strobilus has an outer surface of densely arranged hexagonal plates that spread apart when mature, allowing the spores to waft away like fine dust.
