PLANT SYSTEMS
Group of structures designed to function together as a unit
SYSTEM
Green portion
BLADE
Mark left where leaf had previously been attached
Leaf Scar
Most of a plant. Consists of Epidermal, cork, parenchyma, and support / strengthening
Structural Tissue. Other two major types are Vascular and Meristematic)
Covers and protects
Epidermis
Plant system underground
ROOT
Attaches blade to stem
Petiole
Contains developing leaf
Bud
Vascular tissue that transports water from roots to leaves
Xylem (opposite Phloem)
Openings for transpiration
Stomata
Plant system above ground
Shoot System
Leaf edge
Margin
Shows where one seasons' growth ended
Growth and repair cells
Meristematic
Pallisade and Spongy
Mesophyll
A structure within a system with a definite function or functions
ORGAN
Midrib
One blade on every petiole
Simple. (multiple is compound)
Waxy layer covering epidermal tissue
Cuticle
Run through leaf; contain vascular tissue
Vein
Stem Organ performs what two tasks
Support; movement of nutrients/ food via xylem phloem
small leaf-like or scale-like structure that covered leaf when developing
Stipule
Point as which leave grows from stem
Node; Can be opposite, alternate, or whorled. Basal / Rosette is a leaf cluster on ground.
Meristematic tissue that supports lateral growth
Cambium. (Apical = longitudinal)
Control Stomata
Guard Cells
