Botany Final Exam questions with verified
answers
-T/F- Only herbacous plants will have complete shaft and vascular
bundles Ans✓✓✓True
-T/F- plants close their stomata to prevent dehydration by reducing
water loss from the leaf? Ans✓✓✓TRUE
-T/F- Trees are monocots! Ans✓✓✓FALSE
They are dicots HAHAHAHAHAHAHAHAHAHAH
HA!
allopatric speciation Ans✓✓✓The formation of a new species as a
result of an ancestral population's becoming isolated by a geographic
barrier.
Alternate leaf arrangement Ans✓✓✓I leaf per node
Antenna complex Ans✓✓✓Several hundred chlorophyll a, chlorophyll
b and cartenoid molecules are light-gathering antennae that absorb
photons and pass the energy from molecule to molecule
anticlinal divisions Ans✓✓✓-divisions perpendicular
-give rise to cells laterally
,apoplastic Ans✓✓✓This route of water movement moves it through the
cell walls
are sieve elements alive or dead? Ans✓✓✓alive but have no organelles
companion cells provide life maintenence
As [CO2] increases then O2 will increase or decrease
Ans✓✓✓Decreases
ATP Synthase Ans✓✓✓takes proton charges with potential energy in
the lumen and extracts it to make ATP
bud primordia Ans✓✓✓growth from the apical meristem that will
eventually become a bud (an embryonic shoot, often protected by young
leaves)::: bud primordia develop into lateral shoots
Bundle sheaths Ans✓✓✓protect from phloem feeders, fibers produced
all the way around the vascular bundle
-not all leaves have them
C4 Plants Ans✓✓✓A plant that prefaces the Calvin cycle with reactions
that incorporate CO2 into four-carbon compounds, the end product of
which supplies CO2 for the Calvin cycle.
, Calvin Cycle Ans✓✓✓In photosyntheis, the endergonic carbon-fixation
reactions that assimilate atmospheric CO2 and then reduce it to a
carbohydrate; does not require light in order to occur.
Calvin Cycle Ans✓✓✓series of reactions during the light-independent
phase of photosynthesis in which simple sugars are formed from carbon
dioxide using ATP and hydrogen from the light-dependent reactions
CAM Plants Ans✓✓✓(crassulacean acid metabolism)
-Succulent plants adapted to very arid conditions
-Open their stomata primarily at night and close them during the day.
Casparian strips Ans✓✓✓This structure stops water from moving
through cells apoplastically, making it possible for cells to control water
and ions
-bands tha tsurround like a belt made of suberin and lignin
Chemoustotrophs Ans✓✓✓Autotrophic organisms that use the
oxidation or inorganic substances. Such as sulfur or ammonia as an
energy source to synthesize organic molecules. Unique to some bacteria.
companion cells and sive elements both started as one cell, now sister
cells they separate by the process of Ans✓✓✓differentiation
Compound leaves Ans✓✓✓several blades, or leaflets, that are joined
together and to the stem by several petioles
