What is micropropagation?

in vitro procedure producing large numbers of plants

the root bends downward becaues

high concentration of auxin inhibits root cell elongation

high concentrations of auxin on the shadier side causes

greater growth so the stem grows in a curve towards light

3
gives rise to pith
pachyderm
protoderm
ground meristem
procambium
4
growth in response to gravity
gravitropism
tropism
pick me
phototropism
5
relative ratio of cytokinins and auxins determine ?
whether auxillary buds develop
length of plants
flower development
color of plants
6
the root bends downward becaues
because I'm batman
high concentration of auxin inhibits root cell elongation
high concentration of auxin causes root cell elongation
to increase surface area
7
Micropropagaton can be used to
produce plants with desirable characteristics
all of them
bulk production of endangered plnats
rapidly increase quanity of plants
8
primary meristems are found at the tips of stems and roots
apical meristems
apex meristems
maritime
meristems
9
these allow researchers to detect gene expression
gene expression
microarrays
facial cues
cell differintiation
10
growth towards light
gravitropism
phototropism
island
tropism
11
storing plants in liquid nitrogen (equivalent of a seed bank) is called
cryopreservation
don't pick me
seed bank
genomics
12
high concentrations of auxin on the shadier side causes
greater growth so the stem grows in a curve towards dark
less growth so the stem grows in a curve towards light
less growth so the stem grows in a curve towards dark
greater growth so the stem grows in a curve towards light
13
gives rise to the vascular tissue
ground meristem
pachyderm
procambium
protoderm
14
