photosynthesis and cell respiration

QuestionAnswer
Xylem tissue is a type of... vascular tissue.
Xylem tissue moves water from roots to leaves. True or False. True, xylem moves water from roots to leaves.
How does phytochrome detect light changes? It is turned on or off b/c of red light vs far red light.
Which hormone is most important for thigmotropism and helps vines wrap around a tree? Auxin.
How are plant's eggs fertilized? Sperm.
Which tissue does photosynthetic activity occur? ground tissue.
which tissue is the skin layer of the plant that often has a waxy cuticle? epidermal.
apical meristems cause plants to grow.... taller.
a seed planted upside down will grow in the wrong direction. wrong, because of gravitropism a plant grows accordingly: roots down, sprout up.
Positive phototropism causes what to occur? auxin causes plants to bend toward the light.
ethylene is a plant hormone that aids in.... ripening of the fruit.
auxin is a plant hormone that aids in... apical dominance.
what provides electrons for the photosynthesis electron transport chain (ETC)? water (H2O)
what stages of cellular respiration makes NADH? (Select all that apply) glycolysis, preparatory reactions, citric acid cycle.
what stage(s) of cell respiration does CO2 get produced? (select all that apply) prep reactions, citric acid cycle.
what happens first if you stop breathing oxygen? electrons stop flowing because O2 needed as electron acceptor.
which molecule has the most stored (potential) energy? ATP
Plants do photosynthesis and cellular respiration. true or false. true. plants DO photosynthesis and cell respiration.
Animals do photosynthesis and cellular respiration. true or false. false. Animals only do cellular respiration
Which is the correct flow of energy in a plant? light energy-> chemical energy (ATP)-> chemical energy (sugar)
what enzyme makes atp, what is the source of energy? ATP synthase!! flowing hydrogen
ATP carries ___ and NADH carries ___... Energy, electrons
a sugar molecule is full of.... potential energy.
placing bananas inside a bag to increase ripening, is caused by trapped abscisic acid. False. it is called by ethylene.
Large table grapes were likely exposed to gibberelin. t/f true. the grapes were exposed to
an indeterminent (keep growing) growth tomato would have higher gibberelins which help the internodes expand, t/f true. an indeterminent (keep growing) growth tomato would have higher gibberelins
auxin does not do this.... maintain seed dormancy
NADPH + NADH are... carriers of electrons and hydrogen
____ donated electrons in photosynthesis and ___ donates electrons in cell respiration for the electron transport chain. water, nadh
