Soil and Roots
Ladiges et al. (2010), 4th ed., Fig. 16.1
Plant Structure
Leafy, green above-ground parts (tops), absorbing light in photosynthesis
Stems connecting the tops and roots
Colourless below ground roots, absorbing water and mineral salts (nutrients)
Flowers and fruits for reproduction (spores in
mosses and ferns)

"Essentially, all life depends upon the soil ... .
There can be no life without the soil and no
soil without life; they have evolved together."
