The photons are captured in the antenna complexes of photosystem I and II by chlorophyll and accessory pigments (see diagram at right). When a chorophyll a molecule at a photosystem's reaction center absorbs energy, an electron is excited and transferred to an electronacceptor molecule through a process called Photoinduced charge separation.
Apr 20, 2017· PS I and PS II are the two photosystems which drive the light reaction of photosynthesis. The first stage of the light reaction occurs in PS II whereas the final stage of the light reaction occurs in PS I. Each of the two photosystems are made up of a collection of proteins and pigments. Chlorophylls are the major pigments found in photosystems.
Photosynthesis occurs in the chloroplasts of the plant cell. It is the process of preparing food by the plants, by utilizing sunlight, carbon dioxide and water. Energy is produced in the form of ATP in the process. Few plant cell help in the transport water and nutrients from the roots and leaves to different parts of the plants.

Pigment is a material that determines a color of a paint and can be attained both naturally and artificially. Same as the principle of colors on all the objects, pigments reflect or transmit light
pigments and the action spectrum of photosynthesis. Photochemical reactions – an outline of the photochemical reactions : 1. electrons in chlorophylls are excited by light energy, without referring to photosystems I and II;
A plant cell diagram, like the one above, shows each part of the plant cell including the chloroplast, cell wall, plasma membrane, nucleus, mitochondria, ribosomes, etc. A plant cell diagram is a great way to learn the different components of the cell for your upcoming exam. Plants are able to do something animals can't, photosynthesize.

pigments from 1(at load line) to 6 (at solvent front). 2. During the lab period draw an outline around the region of each pigment spot, and summarize the information about the leaf pigments in Tables 1 – 4. *** If neatly prepared, the Tables can be included directly in your report; however, messy Tables will not be acceptable and must be retyped.
As the dispersing of pigments is the most important step in paint manufacturing and is necessary for an understanding of dispers ing agents, the underlying process will be discussed here briefly. During dispersing, adhesive forces ( van der Waals) acting between the pigment par .

Data Flow Diagram (DFD) provides a visual representation of the flow of information ( data) within a system. By drawing a Data Flow Diagram, you can tell the information supplied by and delivered to someone who take parts in system processes, the information needed in order to complete the processes and the information needed to be stored and accessed.
Parts of a Hummingbird. Many male hummingbirds have brightly colored throats in red, pink, orange, purple, turquoise or other shades (colors that are created by the feather structure rather than pigments, and may change color in different lights), and even s may show streaks or splotching that can be clues to their identity.
The manufacture of aluminum pigments involves a specialized ballmilling process as the first stage. Here the atomized aluminum is ballmilled in the presence of solvent and a lubricant for a period of five to 40 hours. The lubricant is employed to prevent "cold welding" of .

Photosynthesis occurs in green parts of the plant, mostly the leaves, sometimes the green stems and floral buds. The leaves contain specialised cells called mesophyll cells which contain the chloroplast the pigment containing organelle. These are the actual sites for photosynthesis.
