WSU BIO 106 FINAL CERTIFICATION
EVALUATION COMPLETE QUESTIONS
WITH VERIFIED SOLUTIONS
●● 3 main tissues of a plant
Answer: dermal, vascular, ground
●● Root developed in response to low o2
Answer: pneumatophores
●● What is not a plant hormone
Answer: secretin
●● phototropin/phytochrome
Answer: These receive red light and control plant morphology
●● sclerenchyma vs parenchyma cells
Answer: Sclerenchyma: dead, provide stability
Parenchyma: Living cells, participate in photosynthesis
,●● In a leaf what cell is responsible for o2 and water vapor
Answer: guard cells
●● In the roots plants need more o2 or co2
Answer: o2
●● cohesion vs adhesion
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?
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
Answer: plants adapted to dry climate and little fuuucken water
●● Do you expect at the site of phloem loading a positive or neg
pressure
Answer: +
, ●● add sugar to water, water potential increase or decrease?
Answer: decrease
●● macro vs micro nutrients
Answer: Macronutrients: needed in large amounts
Micronutrients: small amounts
●● ATP in sugar transport is needed for wat?
Answer: Generate a proton gradient to allow co-transport of sugar across
a membrane
●● You have skin, potatoes have skin, therefore you are.....?
Answer: A tomato
●● Is nitrate uptake in plants passive or active?
Answer: Active: It is energy dependent, needs proton gradient
●● why is it difficult for plants to get cations from the soil
Answer: cat-ions are paw-sitive and clay in soil is negatively charged, so
they bind together
