Plants Flashcards
1
Q
Plants with no vascular tissue are:
A
Bryophytes
2
Q
Plants with vascular tissue are:
A
Tracheophytes
3
Q
Describe bryophytes.
A
- most primitive plants
- found in most, shady areas
- small size due to no v.s
- no true roots, stems, leaves
- need H2O for reproduction
- reproduce using spores
4
Q
Describe tracheophytes.
A
Contains 2 types of vascular tissue:
Xylem - transport H2O up from roots
Phloem - transport food during photosynthesis and nutrients to where its needed
-presence of VS allows plants to become tall
-have specialized organs, roots, stems, and leaves
5
Q
What are the two different types of tracheophytes?
A
Seedless and Seeded
6
Q
What are angiosperms? Gymnosperms?
A
Angiosperms = flowers, produce fruit w/ enclosed seeds Gymnosperms = "naked" or exposed seeds
7
Q
Compare monocots vs. dicots:
- Cotyledons
- Root type
- Vascular bundle
- Vascular cambium
- Leaf vein pattern
- Vascular bundle in root
A
Monocot
- one seed leaf (eg. corn)
- fibrous root system (eg. grass)
- scattered
- no vasc. cambrium
- parallel
- ring
Dicot
- two seed leaves (eg. peanut)
- tap root system (eg. carrot)
- in a ring
- in a ring around outer edges
- branching net
- star-shaped
8
Q
What are examples of monocots?
A
Grasses, lilies, iris, orchid, cat tails
9
Q
What are examples of dicots?
A
Most trees and shrubs (not conifers), herbs, dandelions, beans
