The wonder of root development, vital for everything from food production to the establishment of great forests.

Every tiny root has a protective cap of constantly replaced cells. Behind this, around & just above the apical meristem – cells are dividing, reproducing via mitosis (look carefully at the photo & you may see cell nuclei / chromosomes in various stages of division). These cells then elongate & mature further up the root. By this method the root progresses down in to the soil in search of water, nutrients & stability.
