DURING experiments on pigment orientation in chloroplasts and grana, it was necessary to determine the directions in which linearly polarized light is preferably absorbed in a pigment molecule.

Researchers often look to photosynthesis—a process that turns sunlight into chemical energy in plants and bacteria—as a model ...

Yagai. To create these structures, the team modified the chlorophyll molecule by attaching a barbituric acid unit via hydrogen bonding and further added tree-like molecular structures called ...

Their structures are very different, for example: plants have stems, roots, flowers, and fruits, while algae do not. And where plants are always made of many cells, algae may be made from one single ...
