photosynthesis requires sunlight for its nutrients to make their way into the chlorophyll on green plants. This suggests that without direct sunlight‚ photosynthesis will not be completed correctly or the plants functions will not work properly. Majority of plants that undergo photosynthesis have chlorophyll stored within them‚ it is what gives them their green color. However‚ there are few species of plants that don’t acquire chlorophyll‚ but still undergo the process of photosynthesis. Specific Information:

produced from photosynthesis will be larger. Plants can absorb and use light energy because they have a green pigment‚ chlorophyll‚ contained in the chloroplasts in some of their cells. Chlorophyll allows the energy in sunlight to drive chemical reactions. Chloroplasts act as a energy transducers‚ converting light energy into chemical energy. So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy. The equation for photosynthesis

Light Dependent Stage/ photochemical reaction/ light reactions: Word Equation: Water ( Hydrogen ions + Oxygen ((: light + chlorophyll) Site: On the Thylakoid membrane of the chloroplast Major events: • Light absorption o Chlorophyll in the thylakoids absorbs light. The energy absorbed is used for photolysis (splitting

Question 1: You have carried out an investigation into the pigments that make up chlorophyll. Use the chromatogram you obtained when carrying out this investigation. Clearly explain the separation technique of paper chromatography in terms of partition. Calculate the Rf value of one of the constituent pigments and compare it to the book value. A paper chromatography was used to separate the pigments that make up chlorophyll to analyse‚ identify‚ and quantify the components‚ using paper (stationary phase

ause it is less soluble in the solvent and has been slowed down by hydrogen bonding to the cellulose. Chlorophylls contain oxygen and mown and are bound more tightly to the paper than are the other pigments. Chlorophyll a is the primarhy photosynthetic pigment in plants. A molecule of chlorophyll is located at the reaction center of photosystems. Other chlorophyll a molecules‚ chlorophyll and the carotenoids capture light

mixtures in organic chemistry is chromatography. Chromatography is the separated of a mixture of two or more different compounds by distribution between two phases‚ one of which is stationary and the other is moving. Another component that is used is chlorophyll‚ which is the green pigment responsible for the color of leaves. Its presence in leaves is necessary for photosynthesis. Photosynthesis can be defined as the process by which plants use light energy to drive the synthesis of organic compounds.

pigments only absorb a narrow range of light‚ many different color pigments are needed to capture more of the sun’s energy. There are three basic classes of pigments which are chlorophylls‚ carotenoids‚ and phycobilins. There are several kinds of chlorophyll and they are greenish pigments. The most important one is chlorophyll A which is very important in making photosynthesis possible. Carotenoids are red‚ orange or yellow pigments and phycobilins are water soluble pigments found in the cytoplasm
