Term
Wavelength
Definition
the distance in the line of advance of a wave from any one point to the next point of corresponding phase
Term
Pigments
Definition
any of various permanently or intermittently colored conjugated proteins and especially hemoglobin that function in the transfer of oxygen in cellular respiration
Term
Chlorophyll
Definition
the green photosynthetic pigment found chiefly in the chloroplasts of plants and occurring especially as a blue-black ester C55H72MgN4O5 or a dark green ester
Term
Thykaloids
Definition
any of the membranous disks of lamellae within plant chloroplasts that are composed of protein and lipid and are the sites of the photochemical reactions of photosynthesis
Term
Chloroplast
Definition
a plastid that contains chlorophyll and is the site of photosynthesis
Term
Electron transport chain
Definition
Term
NADPH
Definition
the reduced form of NADP
Term
ATP
Definition
a phosphorylated nucleotide C10H16N5O13P3 composed of adenosine and three phosphate groups that supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis especially to ADP —called also adenosine triphosphate
Term
Ions
Definition
an atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons
Term
Carrier protiens
Definition
Term
Electron acceptor
Definition
Term
ADP
Definition
a nucleotide C10H15N5O10P2 composed of adenosine and two phosphate groups that is formed in living cells as an intermediate between ATP and AMP and that is reversibly converted to ATP for the storing of energy by the addition of a high-energy phosphate group —called also adenosine diphosphate
Term
Light-dependent
Definition
Term
Carbon (dioxide) fixation
Definition
Term
Stroma
Definition
a compact mass of fungal hyphae producing perithecia or pycnidia b : the colorless proteinaceous matrix of a chloroplast in which the chlorophyll-containing lamellae are embedded
Term
Calvin cycle
Definition
the cycle of enzyme-catalyzed dark reactions of photosynthesis that occurs in the chloroplasts of plants[image] and in many bacteria and that involves the fixation of carbon dioxide and the formation of a 6-carbon sugar
Term
Light-independent
Definition
Term
Glucose
Definition
 a crystalline sugar C6H12O6; specifically : the sweet colorless soluble dextrorotatory form that occurs widely in nature and is the usual form in which carbohydrate is assimilated by animals
Term
Carbohydrates
Definition
any of various neutral compounds of carbon, hydrogen, and oxygen (as sugars, starches, and celluloses) most of which are formed by green plants and which constitute a major class of animal foods
Term
Starch
Definition
to stiffen with or as if with starch
Term
Cellulose
Definition
a polysaccharide (C6H10O5)x of glucose units that constitutes the chief part of the cell walls of plants, occurs naturally in such fibrous products as cotton and kapok, and is the raw material of many manufactured goods (as paper, rayon, and cellophane)
