BIOL 121 EXAM 1 PURDUE QUESTIONS WITH
COMPLETE SOLUTIONS
2 Stages of Photosynthesis Correct Answers light reactions and
dark reactions
Absorption Spectrum Correct Answers The range of a pigment's
ability to absorb various wavelengths of light.
Action Spectrum Correct Answers A graph that profiles the
relative effectiveness of different wavelengths used in
photosynthesis
Amniocentesis Correct Answers needle puncture of the
amniotic sac to withdraw amniotic fluid for analysis
Anaphase 1 Correct Answers homologous pairs separate
each cell gets 1 kind of chromosome
Anaphase 2 Correct Answers centromere divides
sister chromatids separate
Anaphase Correct Answers - chromatids separate (new
chromosomes)
- move to opposite ends
Asexual Correct Answers all genes from single parent
exact copies
, Asexual Reproduction types Correct Answers Binary Fission,
Budding, Fragmentation, Vegetative Reproduction,
Parthenogenesis
ATP Correct Answers (adenosine triphosphate) main energy
source that cells use for most of their work
ATP + water = Pi + 7.3 kcal/mol
Binary Fission Correct Answers A form of asexual reproduction
in single-celled organisms by which one cell divides into two
cells of the same size
Budding Correct Answers Asexual reproduction in which a part
of the parent organism pinches off and forms a new organism
C3 Plants Correct Answers efficient at photosynthesis in cool
wet climates
C4 Plants Correct Answers separation of fixation of CO2 &
making sugar
CO2 + PEP gives oxaloacetate
PEP has high affinity for CO2
stomates closed during high temp and light so O2 competes with
CO2 for RuBP
CAM plants Correct Answers -separation of process in time
