In B. ipanemense, B. involutum and B. weddellii the papillose epidermal cells were densely stained, with basal nuclei and many droplets, as well as amyloplasts.
The tonoplast has been shown to undulate when amyloplasts impact it, possibly ejecting ions in the process because the vacuole sequesters and extrudes ions.
The vegetative cell cytoplasm is very dense, filled with numerous small vesicles, mitochondria, lipidic globules, amyloplasts and ERr with extended cisternae.
A few times, dots are observed in the stroma of the amyloplasts.
Stromules have been recorded on all major plastid types, including proplastids, chloroplasts, etioplasts, leucoplasts, amyloplasts, and chromoplasts.
Very few dots are localized in the stroma of the amyloplasts.
