All green (chlorophyll-containing) plants are phototrophic ‒ Chemosynthetic: derive energy from chemicals for use in the manufacture of organic molecules eg. some bacteria HETEROTROPHS: rely on consuming an external source of organic molecules eg. All animals‚ fungi and

REVIEW OF RELATED LITERATURE The bilimbi‚ Averrhoa bilimbi‚ L.‚ (Oxalidaceae)‚ is closely alliedto the carambola but quite different in appearance‚ manner of fruiting‚flavor and uses. The only strictly English names are "cucumber tree"and "tree sorrel"‚ bestowed by the British in colonial times. "Bilimbi" isthe common name in India and has become widely used.Bilimbisare all much the same wherever they are grown‚ but P.J.Wester reported that a form with sweet fruits had been discovered inthe Philippines

using the method of paper chromatography. Thanks to this technique the pigments were painted on the strip of paper‚ and we were able to calculate the distance each of them went up: the Rf value. We saw that carotene went the farther up and that chlorophyll ’a’ stayed next to the bottom part of the paper. Because the pigments have specific characteristic rate of movement they were able to be separated. Another objective of this experiment was to measure the rate of photosynthesis by the use of a spectrophotometer

to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae. Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs in stems.. The upper and lower epidermal cells do not have chloroplasts‚ thus photosynthesis does not occur there. They
