You don’t need a microscopeto see large clumps of white,fluffy fungi. Underground,fungi make stickysubstances that helpstop tiny spaces fromcollapsing. Thesespaces keep waterand air in the soil.Microbesdecompose (breakdown) leaves.Soil spacesMicrobes help to keep agood structure in soil. Theycreate tunnels and caverns,and make a special gluethat keeps the spaces open.Water and air, which plantsneed to stay alive, movethrough these spaces.Trouble makersSome soil microbes makeplants ill. Raindrops cansplash off soil, picking upand carrying these microbesto the leaves of plantsabove. Little plants on theground can stop this fromhappening by catching theraindrops before theysplash on the soil.Single cellsLiving things are made upof miniscule parts calledcells. You contain trillionsof them! However, mostmicrobes are ‘single celled’- the whole creature is
made of just one cell.Hidden heroesMicrobes can do good thingsfor plants. Some protect theroots of plants by releasingchemicals called antibiotics.These kill other microbesthat can harm plants andimprove the plant’s abilityto fight off disease. On topof that, some of them glowin the dark!042-043_Microscopic_life.indd 42 08/11/2019 09:39
