| phototropic |
Phototropism or heliotropism are botanical terms for an organism response to light (in the case of heliotropism, specifically the light from the Sun). These are one of the many plant tropisms or movements in response to extermal stimuli. Growth toward a light source is a positive phototropism, while the reverse is called negative phototropism or skototropism. ...

| photoluminescence |
Fluorescence is a luminescence, i.e. optical phenomenon in cold bodies, in which a molecule absorbs a high-energy photon, and re-emits it as a lower-energy (longer-wavelength) photon. The energy difference between the absorbed and emitted photons ends up as molecular vibrations (heat). Usually the absorbed photon is in the ultraviolet, and the emitted light (luminescence) is in the visible range, but this depends on the absorbance curve and Stokes shift of the particular fluorophore. ...

| photometry |
Photometry is a technique of astronomy concerned with measuring the flux, or intensity of an astronomical object's electromagnetic radiation. Usually, photometry refers to measurement over large wavelength bands of radiation; but, when not only the amount of radiation but its spectral distribution are measured the term spectrophotometry is used. ...

| photon |
Photon was a live action series based on the infrared tag game popular in the 1980s. The series took place on Earth and in space on various worlds and involved a young human teen named Christopher Jarvis who is a champion player of Photon. He receives a mysterious message one day while playing and is transported to the ship of Mother One, the leader of the Federation of Light a galactic amalgam of beings dedicated to playing Photon and the power of good over evil. ...

| photoautotroph |
Phototrophs or photoautotrophs are photosynthetic algae, fungi, bacteria and cyanobacteria which build up carbon dioxide and water into organic cell materials using energy from sunlight. One product of this process is starch, which is a storage or reserve form of carbon, which can be used when light conditions are too poor to satisfy the immediate needs of the organism. ...
