PLANT BODY
• Shoot system (leaves+stem)
• Root system
• Meristem (cells that divide for life of plant, can give rise to all plant structures)
PLANT TISSUES
• Vascular Tissue• Transport
• Support
• Ground Tissue• Synthesis of Sugars
• Storage
• Support
• Dermal Tissue• Protection
LEAF
• Leaf = blade + petiole• Func: conserves water, site for gas
exchange, site of photosynthesis
Blade
Petiole
STRUCTURE OF A LEAF
Conserves water
PhotosynthesisTransports sugar
and water to stem and roots
STEM
• Stem = series of nodes and internodes• Func: holds the leaves, substance
transportation through vascular tissue
Xylem conducts waterand minerals
Phloem transportssugar
LATERAL MERISTEM
• Causes the stem to grow in width
ROOT
• Func: Anchors plant in soil; takes up water and minerals from soil
MONOCOT vs DICOT
How do monocots differ from dicots? And, how do dicots differ from monocots?
LEAF
MONOCOT:
Veins are parallel to one another
DICOT:
Veins are netted
LEAF
MONOCOT:
Veins are parallel to one another
DICOT:
Veins are netted
STEM (Vascular Bundles)
MONOCOT:
Scattered throughout the stem
DICOT:
Arranged in a circle
STEM (Stem Types)
MONOCOT:
Herbaceous
DICOT:
Herbaceous or woody
ROOT SYSTEM
MONOCOT:
Fibrous root
DICOT:
Tap root
FLOWER
MONOCOT:
Usually in multiples of 3
DICOT:
Usually in multiples of fours or fives
SEED (No. of cotyledons (embryonic leaves)
MONOCOT:
one
DICOT:
two
