Vocabulary : Photoscope to Phototelescope

Photoscope : Anything employed for the observation of light or luminous effects.
Photoscopic : Of or pertaining to the photoscope or its uses.
Photosculpture : A process in which, by means of a number of photographs simultaneously taken from different points of view on the same level, rough models of the figure or bust of a person or animal may be made with great expedition.
Photosphere : A sphere of light; esp., the luminous envelope of the sun.
Photospheric : Of or pertaining to the photosphere.

Photosynthesis : The process of constructive metabolism by which carbohydrates are formed from water vapor and the carbon dioxide of the air in the chlorophyll-containing tissues of plants exposed to the action of light. It was formerly called assimilation, but this is now commonly used as in animal physiology. The details of the process are not yet clearly known. Baeyer's theory is that the carbon dioxide is reduced to carbon monoxide, which, uniting with the hydrogen of the water in the cell, produces formaldehyde, the latter forming various sugars through polymerization. Vines suggests that the carbohydrates are secretion products of the chloroplasts, derived from decomposition of previously formed proteids. The food substances are usually quickly translocated, those that accumulate being changed to starch, which appears in the cells almost simultaneously with the sugars. The chloroplasts perform photosynthesis only in light and within a certain range of temperature, varying according to climate. This is the only way in wh
Phototaxis : Alt. of Phototaxy
Phototaxy : The influence of light on the movements of low organisms, as various infusorians, the zoospores of certain algae, etc.; also, the tendency to follow definite directions of motion or assume definite positions under such influence. If the migration is toward the source of light, it is termed positive phototaxis; if away from the light, negative phototaxis.
Phototelegraphy : Telegraphy by means of light, as by the heliograph or the photophone. Also, less properly, telephotography.
Phototelescope : A telescope adapted for taking photographs of the heavenly bodies.
