The embryo. (A, B) Distal embryo cells (near the micropyle). (A) Lateral embryo cells (Eb) neighbouring a perisperm cell. Without post-fixation. (B) Apical embryo cells. OsO4 post-fixation. (C–F) Proximal (chalazal side) embryo cells showing large protein bodies and oil bodies filling the cells: (C) without post-fixation; (D) OsO₄ post-fixation; (E) protein body containing a large crystal – without post-fixation; (F) proximal embryo cell neighbouring endosperm cells – KMnO₄ post-fixation. Abbreviations: Eb, embryo; Es, endosperm cell; M, mitochondria; N, nucleus; OB, oil body; PB, protein body; Ps, perisperm cell.
