|
two major groups of angiosperms
|
eudicots (dicots)
monocots |
|
|
cabbage, daisies, flowering shrubs, trees
|
eudicots
|
|
|
orchids, palms, grasses, crop plants, rice
|
monocots
|
|
|
5 characteristics between monocots and dicots
|
-one cotyledon vs two
-parallel veins vs netlike veins -vascular bundles arranged vs vascular bundles in a ring -fibrous root system vs taproot system -floral parts in multiples of 3 vs flower parts in multiple of 4 or 5 |

angiosperm diagram
|
study it
|
|
|
how is water transported in root system?
|
passive transport by osmosis or aquaporins
|
|
|
transport of water through cell wall
|
apoplastic pathway
|
|
|
transport of water and solutes through cytoplasm
|
symplastic pathway
|
|
|
responsible for primary growth, elongation of shoots and roots
|
apical meristem
|
|
|
absorb H20 and minerals from soil, increase surface area of epidermis
|
root hair
|
|
|
a waxy layer between endodermal cells to allow water but block apoplastic transfer of mineral flow into vascular cylinder (xylem)
|
casparian strip
|
|
|
type of mineral transport
|
active transport
-use H+ gradient by ATP by definition to make minerals enter root hair cells |
|
|
cation uptake into plant cells
|
K+ enter cells by cation driven
|
|
|
anion uptake into cells
|
NO3- - cotransporters transport Anion and H- into cells
|
|
|
where do minerals go once they enter root hair cells?
|
sent to xylem through symplastic pathway
|
|
|
Xylem transports h20 and minerals from root tip to leaf tip=one direction
|
got it?
|
|
|
three properties of water and definition?
|
tension - ability to pull H20 column without breaking
cohesion - H20 sticks to each other by H bonds adhesion - H20 sticks to cell wall of xylem against gravity |
|
|
structures in a leaf that do photosynthesis?
|
palisade mesophyll cell, spongy mesophyll cells
-mesophyll in general |
|
|
which structures of a leaf transport sucrose
|
phloem
|
|
|
which structure of a leaf transport water
|
xylem, water exchange through stoma
|
|
|
how is sucrose transported to phloem from mesophyll cells?
|
active transport across the H+ gradient using ATP, forces nutrients to enter phloem cells
|
|
|
source plant organ
|
leaf
|
|
|
sink plant organ
|
fruit
|
|
|
direction of sucrose after made
|
source to sink
|
|
|
cotransporters transport neutral and H+ into phloem cells
|
neutral (sucrose) solute uptake
|
|
|
tissue closest to the center of the stem in each vascular bundle
|
pith
|
|
|
produce secondary xylem cells on inside of meristem, produce secondary phloem cells on the outside of the meristem
|
vascular cambium (lateral meristem)
|
|
|
produce thickened cork cells
|
cork cambium (also lateral meristem) secondary growth
|
|
|
annual rings are seen in temperate zone trees because
|
phloem cell size and xylem cell size varies with season
|
|
|
diagram of components of flower
