3154957449	photosynthesis	The process by which plants, algae, and some protists and prokaryotes convert light energy to chemical energy that is stored in sugars made from carbon dioxide and water.	0
3154957450	autotroph	An organism that makes its own food (often by photosynthesis), thereby sustaining itself without eating other organisms or their molecules. Includes plants, algae, and numerous bacteria.	1
3154960324	photoautotroph	An organism that obtains energy from sunlight and carbon from CO2 by photosynthesis.	2
3154970239	heterotroph	An organism that obtains organic food molecules by eating other organisms or substances derived from them; a consumer or a decomposer in a food chain.	3
3155050892	chlorophyll	A green pigment located within the chloroplasts of plants algae and in the membranes of certain prokaryotes.	4
3155053781	mesophyll	Leaf cells specialized for photosynthesis; a leaf's ground tissue system.	5
3155056803	stoma	A microscopic pore surrounded by guard cells in the epidermis of a leaf.	6
3155070321	stroma	The dense fluid within the chloroplast that surrounds the thylakoid membrane and is involved in the synthesis of organic molecules form carbon dioxide and water. Sugars are made here by the Calvin cycle.	7
3155070322	thylakoid	A flattened membranous sac inside a chloroplast. Thylakoid membranes contain chlorophyll and the molecular complexes of the light reactions of photosynthesis. A stack is called a granum.	8
3155303382	light reactions	The first of two stages in photosynthesis; the steps in which solar energy is absorbed and converted to the chemical energy of ATP an NADPH, releasing oxygen in the process.	9
3155307429	NADP+	Nicotinamide adenine dinulceotide phosphate, an electron acceptor that, as NADPH, temporarily stores energized electrons produced during the light reactions.	10
3155312228	Calvin cycle	The second of two stages of photosynthesis; a cyclic series of chemical reactions that occur in the stroma of a cholorplast, using the carbon in CO2 and the ATP and NADPH produced by the light reactions to make the energy-rich sugar molecule G3P.	11
3155315696	carbon fixation	The incorporation of carbon from atmospheric CO2 into an organic compound.	12
3155384928	wavelength	The distance between crests of adjacent waves, such as those of the electromagnetic spectrum.	13
3155386727	electromagnetic spectrum	The entire spectrum of electromagnetic radiation ranging in wavelength from less than a nanometer to more than a kilometer.	14
3155424586	photon	A fixed quantity of light energy. The shorter the wavelength of light, the greater the energy.	15
3155424587	photosystem	A light-capturing unit of a chloroplast's thylakoid membrane, consisting of a reaction-center complex surrounded by numerous light-harvesting complexes.	16
3155551003	photophosphorylation	The production of ATP by chemiosmosis during the light reactions of photosynthesis.	17
