Plant Quest Flashcards
1
Q
xylem
A
- vascular tissue
- transports water from roots to leaves ONLY
2
Q
phloem
A
- vascular tissue
- transports sugar throughout the plant
- any direction
3
Q
what is transported throughout a plant?
A
water, minerals, and nutrients
4
Q
transpiration process
A
- water is absorbed by roots
- water travels thorough plant
- water evaporates from leaf surface
5
Q
what tissue is used in transpiration
A
xylem, for long distance transport
6
Q
translocation
A
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
7

classifications of moss:
A
- bryophytes
- moist habitats
- nonvascular
- gametophyte dominant
8
Q
classifications of ferns:
A
pteridophyta
- moist habitats
- vascular
- sporophyte dominant
9
Q
gymnosperms classifications
A
- vascular
- pollen
- seed bearing
- sporophyte dominant
- conifers (produce both male and female cones)
- wind pollinated
10
Q
angiosperm classifications:
A
- vascular
- pollen
- seed bearing
- flowering
- fruit
- sporophyte dominant
11
Q
angiosperm reproduction:
A
double fertilization
12
Q
growth in response to light
A
phototropism
13
Q
growth in response to gravity
A
gravitropism
14
Q
growth in response to touch
A
thigmotropism
15
