Plant Structure Flashcards
Root functions
- Anchor
- Absorb water
- Store food
Two root types
Tap roots: One main root
Fibrous roots: Many equal-sized roots
Where are XYLEM and PHLOEM in TS of root
XYLEM is a ‘+’ shaped tube. The PHLOEM surrounds it.
Stem functions
- Support arial parts of the plant
- Transport water
- Transport food
Where are XYLEM and PHLOEM in TS of stem
XYLEM is on the inside and PHLOEM is on the outside (the same as in the root tissue diagram)
Leaf functions
- Photosynthesis
- Transpiration
- Gas exchange
Flower function
Reproduction (pollination)
Three differences between Monocots and Dicots
Monocotyledons:
- One cotyledon
- Vascular bundles scattered in the stem
- Leaf venation = parallel
Dicotyledons:
- Two cotyledons
- Vascular bundles in a ring pattern
- Leaf venation = Netted
Autotrophic
Makes its own food
Name 3 metabolic processes
Photosynthesis, respiration, growth (and reproduction)
Name 3 materials transported in plants
Water, carbon dioxide, minerals
How does water uptake occur?
Water enters the root hair by osmosis
How have roots adapted for water uptake?
Thin walls, large surface area
Name 2 mechanisms that cause the upward movement of water through the stem
Root pressure, transpiration
Water evaporates from leaf cells in…
Transpiration
