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."
