WSU BIO 106 FINAL EXAM
QUESTIONS & CORRECT BEST
ANSWERS
Apoplast vs symplast - Correct Answer ✔✔ Apo plastic route water and solutes move
along the continuum of cell walls and extracellular spaces
3 main tissues of a plant - Correct Answer ✔✔ dermal, vascular, ground
Root developed in response to low o2 - Correct Answer ✔✔ pneumatophores
What is not a plant hormone - Correct Answer ✔✔ secretin
phototropic/phytochrome - Correct Answer ✔✔ These receive red light and control plant
morphology
sclerenchyma vs parenchyma cells - Correct Answer ✔✔ Sclerenchyma: dead, provide
stability
Parenchyma: Living cells, participate in photosynthesis
In a leaf what cell is responsible for o2 and water vapor - Correct Answer ✔✔ guard
cells
In the roots plants need more o2 or co2 - Correct Answer ✔✔ o2
cohesion vs adhesion - Correct Answer ✔✔ Cohesion ex: water molecules interacting
with other water molecules
Adhesion ex: water molecules interact with other non water molecules
Where is the Casparian strip and it's function? - Correct Answer ✔✔ Located in the
endodermis. Blocks passive flow of material such as water and solutes into the root of
the vascular tissue of the plant
Xeryphytes - Correct Answer ✔✔ plants adapted to dry climate and little fuuucken water
Do you expect at the site of phloem loading a positive or neg pressure - Correct Answer
✔✔ +
add sugar to water, water potential increase or decrease? - Correct Answer ✔✔
decrease
, macro vs micro nutrients - Correct Answer ✔✔ Macronutrients: needed in large
amounts
Micronutrients: small amounts
ATP in sugar transport is needed for wat? - Correct Answer ✔✔ Generate a proton
gradient to allow co-transport of sugar across a membrane
You have skin, potatoes have skin, therefore you are.....? - Correct Answer ✔✔ A
tomato
Is nitrate uptake in plants passive or active? - Correct Answer ✔✔ Active: It is energy
dependent, needs proton gradient
why is it difficult for plants to get cations from the soil - Correct Answer ✔✔ cat-ions are
paw-sitive and clay in soil is negatively charged, so they bind together
In Frits coleoptile experiment, what was the most likely phytohormone transported from
the coleoptile tip into the agar block? - Correct Answer ✔✔ auxin
nitrogenase - Correct Answer ✔✔ catalyze atmospheric o2 to ammonia
potato growth from dark to light conditions - Correct Answer ✔✔ example of
photomorphism
endo vs ectomycorrhizae - Correct Answer ✔✔ endo: grow in invaginations of the root
cell membranes called arbuscules
Ecto: do not penetrate the root cortex
how do roots gain length? - Correct Answer ✔✔ elongation, not cell division
plant hormone responsible for "triple response" - Correct Answer ✔✔ ethylene
lateral meristems? - Correct Answer ✔✔ secondary growth
plant hormones responsible for leaf abscission? - Correct Answer ✔✔ auxin and
ethylene
what is an action spectrum? - Correct Answer ✔✔ depicts the relative effectiveness of
different wavelengths of radiation on driving certain physiological processes
xylem sap contains? - Correct Answer ✔✔ water and minerals
