The Secret in the Seed


              prevents the leaves from being shed or the plant from wilting. And
              moreover, most coniferous trees have needle-shaped leaves that are re-
              sistant to frost.
                   Every spring, these plants gather more energy when new leaves
              unfurl. The resilience of the leaves is important for these plants, inas-
              much as they store nutrients by photosynthesis whenever weather
              conditions permit. Non-deciduous trees are usually conical in shape,
              which prevents their branches from breaking under too much accumu-
              lation of snow. What snow does settle on them insulates the tree from
              sub-zero cold and prevents water loss by reducing loss of moisture
              from the leaves. 1
                   For plants living in
              the desert, drought is
              one of the greatest dan-
              gers. Negative factors
              such as sporadic rainfall,
              sand storms and intense
              heat would normally
              mean extinction for de-
              sert plants. But species
              living in arid climates
              enjoy special features
              that enable them to
              withstand their environ-
              ment. Their seeds’ struc-

              Every species of tree
              has different struc-
              tural features. All the
              information relating to
              these features is
              stored in its seeds.
