Root Morphology Flashcards
Primary Functions of Roots
Anchoring in soil
uptake of water and minerals
hormone production
storage
asexual reproduction
microbial community interactions
roots- anchoring in soil
hold plant in place
prevents from blowing away
hold soil in place
what do prop roots provide
additional stability
what do holdfast roots provide
anchoring and climbing
where do holdfast roots come out of
stem
what plant has prop roots
corm
how do roots uptake water and minerals
thorugh soil through diffusion
direct contact
water potential gradient
water potential gradient
amt of water pressure
TF root must come in direct contact with water and nutrients
T
Rhizosphere
soil that is immediate;y touching the root
haustorium
specializzed roots of a parasitic plant to get sugars from host
cytokinin
root to shoot communication
Where is cytokinin produced
root ti[
Adventitous root
roots that develop from somewhere other than primary root
TF soil is alive
T
Why does the root have a cylindrical shape
helps push through soil
water and nutroents come from all sides
TF root growth decreases as compaction increases
T
Is there a ratio between roots and chutes
yes
What does root death put back into the soil
C
Are taproots found more in monocots or dicots
dicots
what does the taproot develop from
radicle
TF the radicle first formed at germination
F, its alive inside of seed
are lateral roots the same as branch roots
yes
are lateral roots the same as secondary roots
yes
Teriary root
comes form secondary roots
Fibrous roots
adventitous roots
from base of stem
adventitous roots
also fiborous roots from base of stem
lateral roots
roots off of adventitious roots
plant morphology
study of structures of external features
plant anatomyq
study of the structure of the internal features cellular and molecular levels
What is the root cap made of
thin parenchyma cells
function of root cap
push through soil
protect apical meristem
zone of division what is found in it
apical meristem
zone of elongation
where cells elongate
what is zone of primary maturation also known as
root hair zone
what do root hairs do
increase SA
easy wat to get water, not a lot of energy
Zone of primary maturation
specialized cells and parenchyma cells mature
Zone of secondary maturation
where lateral roots form
where secondary growth occurs for woody roots
Does secondary growth form secondary roots
no
Where zone is secondary xylem and phloem produceccd
secondary maturation
TF secondary growth = lateral growth
F
