Figure 3: Ultrastructure of starch granules and protein formation and accumulation in testa cells of G. biloba seeds. (a) Some starch granules accumulated in cells 20 days after pollination; (b) Starch granule accumulated in chloroplast; (c) lipid drops accumulated in chloroplast; (d) many starch granules accumulated in plastid 25 days after pollination (arrows, Er); (e) protein bodies formed by 25 days after pollination; (f) starch granules formed by 30 days after pollination; Er: endoplasmic reticulum; LD: lipid drop; P: protein body; Pl: plastid; Mi: mitochondrion; N: nucleus; S: starch granule; Th: thylakoid; W: wall. ((a), (d), (e), and (f)) bar = 2 μm; (b) bar = 0.5 μm; (c) bar = 1 μm.
