Natur-Blätter-3
Das Blatt ist neben der Sprossachse und der Wurzel eines der drei Grundorgane der höheren Pflanzen. Der Reichtum an Blattformen ist enorm. Das saftige Grün der Blätter lässt uns Vitalität und Lebenskraft spüren. In botany, a leaf is an above-ground plant organ specialized for photosynthesis. For this purpose, a leaf is typically flat (laminar) and thin, to expose the cells containing chloroplast to light over a broad area, and to allow light to penetrate fully into the tissues. Leaves are also the sites in most plants where transpiration and guttation take place. Leaves can store food and water, and are modified in some plants for other purposes.
