Primary tissues Flashcards
Gymnosperm means
developing seed exposed to atmosphere
angiosperm means
enclosed seed
What are the 2 subcatagories of Angiosperms
Monocots
Dicots
based on seed leaves
Monocot characteristics (6)
One seed leaf
Parallel
Flower parts in 3
Fibrous root system(lots of smaller roots)
Pollen most monosulcate (single pore)
<10% woody
Dicot characteristics(6)
two seed leafs
netted leaf veins
flowers in 4s and 5s
primary taproot
stem vascular bundles are in a ring
pollen mostly tricolpate
>50% woody
Meristem
tissues that contain actively dividing cells
4 types of meristems
Apical meristem
axillary buds give rise to axillary meristem
lateral meristem
intercalary meristem
DICOT- apical meristem
vegitative vs reproductive dicot
the top of the plant-adds to shoot length
vegitative- produces leaves
reproductive- produces flowers
the stem between 2 nodes
internode
DICOT what makes up a leaf
Lamina (leaf blade) and petiole(twiggy thang)
DICOT where does the leaf attach to the stem
node
DICOT Axillary bud location
and function
between stem and petiole
contains axillary meristem
gives rise to axillary branch or flowers
DICOT what hormone controls axillary bud
IAA- auxin
DICOT root morphology
taproot and series of lateral roots branching from it
apical meristem at root tip
