Lichen

A lichen is not one organism. It is a fungus and an alga living as one body. The fungus provides the structure and holds water. The alga photosynthesises and makes sugar. Separated, the fungus starves and the alga dries out. Because it needs no soil, a lichen can grow on bare rock, on gravestones and on the roofs of cars that have not moved for a decade. Lichens grow extremely slowly — some crustose species less than a millimetre a year. Scientists use that rate to date rock surfaces, a method called lichenometry. Lichens also absorb whatever is in the air. Where the air is dirty, they disappear, which makes them a living measure of pollution.

  1. 1. What would a diagram of a lichen need to label?

Why Clocks Agree

Until the 1840s, every British town kept its own time, set by the sun. Noon in Bristol was about ten minutes after noon in London. That was no problem while the fastest thing on the road was a horse. The railways changed it. A timetable cannot work if every station measures noon differently, and trains sharing a track need to agree about when. So the railway companies imposed London time on their whole network. People called it railway time. Some towns kept two minute hands on the town clock for years, one local and one railway. In 1880 Parliament made a single time legal across the country. The sun had been overruled by the timetable.

  1. 1. What would an illustration of a two-handed town clock convey?
