Fig. 6. Size distribution of components, modules and compartments involved in phytochemical metabolism and storage. Sizes range from 2 nm for a single phospholipid, the main component of biological membranes, to 120 μm for an embedded gland surrounded by multiple cells. The geometrical dimensions shown are in some cases somewhat arbitrary, e.g. because a gene sequence may be in a supercoiled configuration or in an open configuration as when transcribed.
