Figures & data
Figure 1. Food bodies of the leaf of C. pachystachya. A, General aspect of the young leaf before stipule rupture, arrows indicate FBs; B, fully developed FB, note a fragile stalk; C–D, FBs observed under SEM, note the dense indumentum and, in D, the stalk rupture; E–F, detail of the surface of a FB showing thin cuticle and a pore (arrow). Abbreviations: cc, central cells; ep, epidermis; st, stalk.
Figure 2. Diagram showing major developmental stages of FBs on the leaf of C. pachystachya. A, Initial stage of FB formation, note the elevation of epidermis due to proliferation of the underlying tissue; B–C, FB at the expansion stage, note the effects of cell expansion and, in C, the persistence of meristematic activity in the stalk cells.
Figure 3. Ultrastructural aspects of FBs of the leaf of C. pachystachya. A–B, Epidermal cell with lamellar outer periclinal wall and organelles in peripheral cytoplasm; C–F, parenchyma of the core of the FBs. In C–D note the cell with large vacuole and lobated nucleus. Detail of peripheral cytoplasm with mitochondria is shown in E–F, note in F a large oil droplet. Abbreviations: di, dictyosome; er, endoplasmic reticulum; mi, mitochondria; nu, nucleus; od, oil droplet; va, vacuole.
