Bio 1500 Unit 2 Exam
1. the process by which light energy is used to make food molecules from CO2
and water: photosynthesis
2. where does photosynthesis take place?: in chloroplasts
3. molecules that absorb light of a particular wavelength or color: pigment
4. which wavelengths do chlorophyll absorb?: violet, blue and red wavelengths
5. when a substance absorbs light energy and re-emits it at a different wave-
length: florescence
6. when light energy bounces of an object and is not absorbed: reflection
7. when chemical reactions generate light energy: bioluminescence
8. what happens when a proton is absorbed by a molecule?: -it excites an electron into a
higher energy state
1/5
, -the electron quickly drops to its ground state
-releases the energy as light at a longer wavelength
9. why does isolated chlorophyll in a tube fluoresce red light, but a leaf doesn't?-
: 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
10. -recalling facts and basic concepts
-define, duplicate, list, memorize, repeat, state: remember
11. -explain ideas or concepts
-classify, describe, discuss, explain, identify, locate: understand
12. -use information in new situations
-execute, implement, solve, use, demonstrate: apply
13. -draw connections among ideas
-differentiate, organize, relate, compare, contrast: analyze
2/5
