- #103 The Light-independent Reactions (calvin Cycle)
The light-independent reactions take place in the stroma of the chloroplast, where the enzyme ribulose bisphosphate carboxylase, usually known as rubisco, is found. 1. Carbon fixation CO2 diffuses into the stroma from the air spaces within the...
- #101 Photosynthetic Pigments
Photosynthetic pigments are pigments presented in chloroplasts or photosynthetic bacteria. They capture light energy necessary for photosynthesis and convert it to chemical energy. PigmentsA pigment is any substance that absorbs light.The color...
- #100 Chloroplasts
Photosynthesis takes place inside chloroplasts. These are organelles surrounded by 2 membranes, called an envelope. Chloroplasts are found in mesophyll cells in leaves: - Palisade mesophyll cells contain most chloroplasts. - Spongy...
- #99 Photosynthesis Overview
Photosynthesis is a series of reactions in which energy transferred as light is transformed to chemical energy. Energy from light is trapped by chlorophyll, and this energy is then used to ? split apart the strong bonds in water molecules to release...

chlorophyll or chlorophyl
Term: Chlorophyll or chlorophyl
Origin: Anc Greek ??????/chloros(=green) + ??????/phyllon(=leaf)
Coined: in 1817 by chemists Pierre-Joseph Pelletier (1788-1842) and Joseph Bienaimé Caventou (1795-1877) who used mild solvents to successfully isolate many important biologically active plant products as chlorophyll, caffeine, strychnine, colchicine, quinine and veratrine.
Definition:
Chlorophyll is a green pigment found in photosynthetic organisms and it allows them to convert light energy to chemical energy.
