| The leaves of Crassula ovata contain much water. The cells have large vacuoles and the chloroplasts appear only in the edge (in the cytoplasm). There are numerous vascular bundles but these have a simple structure. The section clearly shows the annular thickenings of the xylem vessels. Phloem elements can be only distinguished from chlorenchym cells because of their small size and longitudinal shape. |
