Coloured transmission electron micrograph (TEM) of chloroplasts from the yellow portion of a yellow/green variegated Coleus blumei plant. Chloroplasts are the sites of photosynthesis, the process that synthesises carbohydrates from carbon dioxide and water using sunlight. The structure of a variegated chloroplast is slightly different from that of a normal green chloroplast. The granal stacks, formed from parallel thylakoids (membranes, bright lines), that contain the chlorophyll pigments are less ordered in the variegated chloroplast. The pigments themselves are also slightly different. Magnification: x14,300 when printed at 10cm wide.

In principle, there should be no limit on how large objects can get and still display quantum behaviour like superpositions. Physicists testing the idea hope to reveal clues about quantum gravity
