They have a dense cytoplasm with irregular shape filled with numerous small vesicles, oil body, abundant amyloplasts
and a prominent centrally placed nucleus (Fig.
Arena starch grains have numerous small and distinctive pressure facets due to the grains packing together very tightly in the amyloplasts
during their formation (Figure 5).
In addition to working as photoassimilate repositories, soybean cotyledons become green and expand, suggesting that their amyloplasts
are transformed into chloroplasts.
would not seem to be involved in gravity perception in C.
If polarized light microscopy is included, it can be used as a tool to identify plant material on the basis of the Maltese cross evident in amyloplasts
when viewed with crossed polars and the birefringence exhibited by cellulosic fibers (for complete instructions for a lab on polarized light microscopy, see McMahon, 2004).
However, suppressors grown on 1% sucrose medium show the presence of some amyloplasts
