AP Biology - Photosynthesis Flashcards

3010178555	photoautotrophs	organisms that produce their own food using light energy - plants, protists, and algae	0
3010180364	mesophyll	inner tissue of a leaf, contain many chloroplasts	1
3010182099	stroma	fluid that fills the inner area of a chloroplast	2
3010183256	thylakoids	found in stacks in the chloroplast where the light reactions occur	3
3010185276	grana	stacks of thylakoids	4
3010185277	chlorophyll	pigment that absorbs light energy to power the light reactions of photosynthesis	5
3010188932	stomata	pores in the epidermis of a leaf that allow water to leave the plant and carbon dioxide to enter it	6
3010190184	light reactions	reactions that use carbon dioxide and water to create ATP and NADPH for use in the calvin cycle	7
3010191718	NADP+	an electron acceptor that is reduced and is used to fuel the calvin cycle	8
3010194048	calvin cycle	the series of reactions where ATP and NADPH are used to form G3P which is then used to form glucose and other organic molecules including amino acids and nucleic acids	9
3010199631	carbon fixation	reactions that use co2 to make glucose	10
3010201978	absorption spectrum	the range of wavelengths absorbed by a particular pigment	11
3010208130	chloroplast	the organelle where photosynthesis takes place	12
3010210672	products of light reactions	NADPH + ATP + O2	13
3010212458	reactants of calvin cycle	NADPH + ATP + CO2	14
3010216389	water	this molecule splits and allows for an electron to be bumped up to the primary electron acceptor in photosystem II	15
3010220190	photosystem II	the location of water splitting	16
3010220218	p700	this is the special chlorophyll that is located in photosystem I	17
3010222902	p680	this is the special chlorophyll that is located in photosystem II	18
3010226488	chemoautotroph	organisms that produce their own food using inorganic materials - thermophilic bacteria	19
3010236761	guard cells	responsible for opening and closing stomata	20
3010238425	photorespiration	process where o2 gets substituted for CO2 in the calvin cycle	21
3010240021	c3 plants	these plants have stomata open during the day and are most efficient in cool/moist conditions in normal light	22
3010242712	c4 plants	these plants have stomata open during the day, but barely open on hot days, work best in high light/temps, use h20 better	23
3010246530	cam plants	these plants only have stomata open at night, convert co2 to an acid that is then broken down during the day - work well in dry conditions	24
