Namely collisions between excited chlorophyll molecules and I-molecules results in energy being transferred from the excited chlorophyll to the I-. The result is that the chlorophyll is –de-excited and the I-excited. In leaves, the chlorophyll transfers its energy to the cholorplasts.

This experiment will be performed in two lab periods. In the first lab period you will extract chlorophyll, the green pigment in leaves, from spinach. In the second lab period you will investigate the interaction of light with chlorophyll.

Chlorophyll is the green pigment responsible for the color of leaves. Its presence in leaves is crucial for photosynthesis. Photosynthesis can be defined as the process by which plants, algae, and photosynthetic bacteria use light energy to drive the synthesis of organic compounds.

The amount of energy an atom can absorb depends on the energy separation of the electronic levels of the atom. If light of frequency, (, is incident on the atom, the atom will absorb this light only if the energy of a photon of this light () equals the energy difference between two electronic levels of the atom.

Chlorophyll (also chlorophyl) is a term used for several closely related green pigments found in cyanobacteria and the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, chloros (green) and φύλλον, phyllon (leaf).

Chloroplast: Photosynthesis. In photosynthesis, the sun's solar energy is converted to chemical energy. The chemical energy is stored in the form of glucose (sugar). Carbon dioxide, water, and sunlight are used to produce glucose, oxygen, and water.

To learn more about organelles that can be found in typical plant cells, see: 1  Cell (Plasma) Membrane-a thin, semi-permeable membrane that surrounds the cytoplasm of a cell, enclosing its contents. 2  Cell Wall-outer covering of the cell that protects the plant cell and gives it shape.

In this experiment you will first extract chlorophyll from spinach via column chromatography in the first lab period. In the second lab period you will investigate the photochemistry of chlorophyll.

A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis. Hence, the name chloroplast indicates that these structures are chlorophyll containing plastids.

Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion.
