Root/Flower/Leaf anatomy Flashcards
Primary root
radical of seed- largest root
Filament (male)
support of Anther
Pedicel
Stem - hold flower erect
lateral root
smaller roots braching off primary root
Petal
showy to attract pollinators
Sepal
protects/surrounds flowers as they develop
What needs do roots fulfill
- anchor
- support
- water uptake
- nutrient uptake
- carbohydrate storage
herbaceous plants cannot store carbs above ground
Ovary (female)
(ovules) genetic material fertilize eggs
can produce many seeds
Pistil (female)
made up of stigma, style, ovary
Receptacle
where everything is plugged in/held together
Stigma (female)
stciky to accept pollen
Perfect Flowers
both stamen and pistil parts
Anthers (male)
where pollen is produced
root cap
protects root tip
lubricates soil to penetrate
root tip
maristem - ABOVE root cap
Node
where leaves or beaches develop
Simple leaves
Style (female)
holds/supports stigma
Imperfect flowers
Missing either stamens or pistils
Stamen
Anther and Filament make up Stamen
Male
Flower anatomy
anther, filament: stamen
pistil: ovary, style,stigma;
petal, sepal, receptacle
root hairs
increase surface area for water
internode
space between nodes
Crown
perennials grow in clumps called crowns
- they can be propagated(divided) as long as there is at least 1 bud
- roots do not contain buds, you need to divide stems to propagate
- divide every few years because centers die
