What is the difference between a primary and a lateral root?
One is found in large plants, the other in small plants
A primary root is the first root to emerge and the lateral root branches off from it
A lateral root is the first root to emerge and the primary root branches off from it
One is better than the other

Node
Leaf
Petiole
Stem
What is the difference between monocot and eudicot vein arrangement?
Both veins are parallel
Monocot leafs have parallel venation, eudicot leafs have a webbed arrangement
Monocot leafs have veins in multiples of 3, eudicot leafs have veins in multiples of 4 or 5
Monocot leafs have webbed venation, eudicot leafs have a parallel arrangement
What are the 3 types of tissues?

Superficial
Dermal
Ground
Dermal tissues include _______ and ___________ plants.
(a)
What is the function of vascular tissue?
Allows for the plant roots to expand
Makes the plant grow taller
Make the plant grow thicker and stronger
Facilitates transport of materials through plant, provides mechanical support
Xylem+Phloem=
Plant growth
Vascular tissue
Stele
What are ground tissues?
Make the plant grow taller
Allow for transport of nutrients in the ground
Tissues that aren’t dermal or vascular.
Sustain the plant in the ground
What is determinate growth?
Limit to growth
Seen a lot in animals
The plant can determine if it will continue growing
Growth stops at a certain age
Apical meristems allow the plants to grow (a)
Lateral meristems allow the plants to grow (a)
What are the 3 zones seen in primary growth?
Zone of growing, zone of elongation, zone of thickenning
Zone of elongation, zone of root spreading, zone of latitude
Zone of cell division, zone of elongation, zone of differentiation/maturation
Zone of cell division, zone of root spreading, zone of differentiation/maturation
What is the vascular cambium?
Adds vascular components to increase vascular flow and support.
Allows for the plant to grow taller
Produces tough, thick covering of waxy cells for protection, prevent water loss

Late wood is formed in the (a)
Growth rings can be used to estimate ________
Climate change
Tree age
Tree type
What is heartwood?

Outer layers that still transport materials through xylem
Exchange of gases
What are characteristics of sapwood?
