EXAM: Bio 1500 - Exam 2 (Mizzou-Bush) Test with
Complete Solutions
the process by which light energy is used to make food molecules from CO2 and water
CORRECT ANS-photosynthesis
where does photosynthesis take place? CORRECT ANS-in chloroplasts
where does photosynthesis take place? CORRECT ANS-in chloroplasts
molecules that absorb light of a particular wavelength or color CORRECT ANS-pigment
which wavelengths do chlorophyll absorb? CORRECT ANS-violet, blue and red wavelengths
when a substance absorbs light energy and re-emits it at a different wavelength CORRECT
ANS-florescence
when light energy bounces of an object and is not absorbed CORRECT ANS-reflection
when chemical reactions generate light energy CORRECT ANS-bioluminescence
, EXAM: Bio 1500 - Exam 2 (Mizzou-Bush) Test with
Complete Solutions
what happens when a proton is absorbed by a molecule? CORRECT ANS--it excites an
electron into a higher energy state
-the electron quickly drops to its ground state
-releases the energy as light at a longer wavelength
why does isolated chlorophyll in a tube fluoresce red light, but a leaf doesn't? CORRECT
ANS-in the leaf, the chlorophyll is coupled to a series of chemical reactions that use the light
energy. in the tube, it emits red light due to a mixture with acetone
-recalling facts and basic concepts
-define, duplicate, list, memorize, repeat, state CORRECT ANS-remember
-explain ideas or concepts
-classify, describe, discuss, explain, identify, locate CORRECT ANS-understand
-use information in new situations
