Phormidium laminosum plastocyanin, PDB: 3BQV . Plastocyanin is a copper-containing protein that mediates electron-transfer. It is found in a variety of plants, where it participates in photosynthesis. The protein is a prototype of the blue copper proteins, a family of intensely blue-colored metalloproteins.
Plato (Greek: Πλάτων, Plátōn, from Ancient Greek: πλατύς, romanized: platys, lit. 'broad') is actually a nickname. Although it is a fact that the philosopher called himself Platon in his maturity, the origin of this name remains mysterious. Platon was a fairly common name (31 instances are known from Athens alone), [8] but the ...
Plastoquinone (PQ) is a terpenoid - quinone (meroterpenoid) molecule involved in the electron transport chain in the light-dependent reactions of photosynthesis. The most common form of plastoquinone, known as PQ-A or PQ-9, is a 2,3-dimethyl-1,4- benzoquinone molecule with a side chain of nine isoprenyl units.
Plastic. Household items made of various types of plastics. Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be molded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties ...

Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix —most often based on thermosetting polymers ...
Plastochron. As the tip of a plant shoot grows, new leaves are produced at regular time intervals if temperature is held constant. This time interval is termed the plastochron (or plastochrone). [1] The plastochrone index and the leaf plastochron index are ways of measuring the age of a plant dependent on morphological traits rather than on ...
