The three stalk wheat design with additional curved openings repeats on both sides of the pot. This pot will be a terrific addition to your display collection and will really show-off your prized plants. Multiple rubber pads are attached to the base to protect surfaces and our 6" crystal clear pot fits nicely in each and a free one is included with each pot ordered.
Pigment molecules are associated with proteins, which allow them the flexibility to move toward light and toward one another. A large collection of 100 to 5,000 pigment molecules constitutes "antennae," according to Vermaas. These structures effectively capture light energy from the sun, in the form of photons. Ultimately, light energy must be transferred to a pigment-protein complex that can convert it to chemical energy, in the form of electrons. In plants, for example, light energy is transferred to chlorophyll pigments. The conversion to chemical energy is accomplished when a chlorophyll pigment expels an electron, which can then move on to an appropriate recipient.

Light-independent reactions (also called dark reactions): ATP and NADPH are rich energy sources, which drive dark reactions. During this process carbon dioxide and water combine to form carbohydrates like glucose. This is known as carbon fixation.
ED - Extra-low Dispersion glass for minimising chromatic aberrations.
Photosynthesis occurs in the chloroplasts, specifically, in the grana and stroma regions. The grana is the of the organelle; a collection of disc-shaped membranes, stacked into columns like plates. The individual discs are called thylakoids. It is here that the transfer of electrons takes place. The empty spaces between columns of grana constitute the stroma (The Cell: A Molecular Approach 2nd Ed, Sinauer Associates, 2000).
Aspheric - Lens element with non-spherical surfuce.
Photosynthetic organisms contain organelles called plastids in their cytoplasm. According to Cheong Xin Chan and Debashish Bhattacharya of Rutgers University (), the double-membraned plastids in plants and algae are referred to as primary plastids, while the multiple-membraned variety found in plankton are called secondary plastids. These organelles generally contain pigments or can store nutrients. In “” (Sinauer Associates, 2000), Geoffrey Cooper enumerates the various plastids found in plants. Colorless and non-pigmented leucoplasts store fats and starch, while chromoplasts contain carotenoids and chloroplasts contain chlorophyll.

are molecules that bestow color on plants, algae and bacteria, but they are also responsible for effectively trapping sunlight. Pigments of of light. Below are the three main groups.
Medical - Macro lens with built-in ring flash.
Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of breathable oxygen and water.
Fisheye - Non-rectalinear lens with extremely wide picture angle.
On the other hand, anoxygenic photosynthesis uses electron donors other than water. The process typically occurs in bacteria such as purple bacteria and . “Anoxygenic photosynthesis does not produce oxygen — hence the name,” said , professor of botany at the University of Wisconsin-Madison. “What is produced depends on the electron donor. For example, many bacteria use the bad-eggs-smelling gas hydrogen sulfide, producing solid sulfur as a byproduct.”
