28 Plant Structure Flashcards
Monocot
One cotyledon
Parrel vein
Scattered vascular tissue
One opening pollen grain
Fibrous
Floral organs 3 multiple
Eudocot
2 Cotyledon
Netlike veins
Ring vascular tissue
Three opening pollen grain
Fibrous roots
Floral organs 5 multiple
Taproot
One large root structure anchors the plant and aches as storage. Allows plants to survive drought
Fibrous
It has a very high area to /v ratio when compared to taproot. Spreads out underground allowing for recourse acquisition. Faster absorption
Root Function
Structure - Anchor
Nutrient uptake / Water uptake
Storage
Stem Function
Transport nutrients and water leaves - roots
Support
Storage
Move stem the best photosynthesis (Auxin bending away)
3 Tissue types of plants
Dermal
Ground
Vascular
Dermal - Protoderm
Thin outer protective layer on Stem, Roots, Leaves
Ground - Ground meristem
Like a filler in the plant covers areas that vascular and dermal do not.
Vascular - Procambuim
Xylem - transport of water
Phloem - transport of sugars
Three types of plant cell
Parenchyma
Collenchyma
Sclerenchyma
Parenchyma
Thin cell wall
Photosynthesis
Alive
Collenchyma
Support when alive
Protection
Alive
Sclerenchyma
Support when dead
Protection
DEAD
Xylem
Tracheids - Tranposrt of water minerals
Vessel elements - system of transportation (tubular vessel)
Phloem
Sieve tube element - transports carbs or sugars.
Companion cells - Providing energy to sieve tube / metabolic support loading and unloading
Primary
Vertical growth
Apical Meristem
Secondary
Horizontal growth
Lateral Meristem
Cork cambium - Epidermis becomes perderm
Vascular cambium - Layers of 2nd Xylem Phloem
Structure Root cell.
Epidermis
Root hairs
Cortex
Endodermis
Pericycle
Root primary growth
Zone Cell Division
Zone Cell Elongation
Zone Cell Maturation
Three tissue creates
Formation lateral root
Shoot primary growth
Same Root
Leaf primordia
Intercalary meristem
Tree rings formed
Vascular cambium - 2nd xylem phloem
Old xylem dies hardens, old phloem falls off
