Plant Quest Flashcards
xylem
- vascular tissue
- transports water from roots to leaves ONLY
phloem
- vascular tissue
- transports sugar throughout the plant
- any direction
what is transported throughout a plant?
water, minerals, and nutrients
transpiration process
- water is absorbed by roots
- water travels thorough plant
- water evaporates from leaf surface
what tissue is used in transpiration
xylem, for long distance transport
translocation
the transport of sugars around a plant in any direction for various reasons including: leaves haven’t grown yet, need to store excess glucose in roots
- phloem
- source cells load at the source, and unload at the sink cells
- this works through diffusion and pressure
classifications of moss:
- bryophytes
- moist habitats
- nonvascular
- gametophyte dominant
classifications of ferns:
pteridophyta
- moist habitats
- vascular
- sporophyte dominant
gymnosperms classifications
- vascular
- pollen
- seed bearing
- sporophyte dominant
- conifers (produce both male and female cones)
- wind pollinated
angiosperm classifications:
- vascular
- pollen
- seed bearing
- flowering
- fruit
- sporophyte dominant
angiosperm reproduction:
double fertilization
growth in response to light
phototropism
growth in response to gravity
gravitropism
growth in response to touch
thigmotropism
auxin
- hormone
- cell growth/ elongation
- phototropism
- rooting
ethylene
- the aging hormone
- aging, fruit ripening, leaf drop
- a gas hormone
monocots
- one cotyledon
- veins usually parallel
- vascular bundles usually complexly arranged
- fibrous root system
- flow
monocots
- one cotyledon
- veins usually parallel
- vascular bundles usually complexly arranged
- fibrous root system
- floral parts usually in multiples of three
dicots
- two cotyledons
- veins usually netlike
- vascular bundles usually arranged in a ring
- taproot usually present
- floral parts usually in multiples of 4 or 5
