1. Plant Structure and Function

2. Three Types of Plant Tissues
Vascular Tissue
Transport
Support
Ground Tissue
Synthesis of Sugars
Storage
Dermal Tissue
Protection

3. Division of Meristem Cells Causes Plant Growth
Apical Meristem
tips of root and shoot
increase in height
Lateral Meristem
cylinders within plant body
increase in width

4. Stoma = opening in the leaf for gas exchange, water evaporation
Plant Body
Leaf = blade + petiole
Functions
Exposes surface to sunlight Major site of photosynthesis Conserves water Provides for gas exchange
Blade
Petiole
Stoma = opening in the leaf for gas exchange, water evaporation

5. Transports water and sugar to stem and roots
Conserves water
Photosynthesis
Transports water and sugar to stem and roots
Structures of the Leaf

6. Phloem transports sugar
Plant Body
Stem: series of nodes and internodes
Functions
Holds leaves up to light
Transports substances through vascular tissue
Phloem transports sugar
Xylem conducts water
and minerals

7. Plant Body Root Functions Anchors plant in soil
Takes up water and minerals from soil

8. Flowering Plant Reproduction
Pollen grains
Ovule
Flower
Meiosis
Mitosis
Flowers are modified leaves, specialized for reproduction.
Flower parts undergo meiosis to produce haploid products
pollen grain
ovule (contains egg cell)

9. A Complete Flower Has Both Male and Female Parts
Produces pollen
Stamen
Anther
Attracts pollinator
Filament
Pistil
Stigma
Petal
Style
Sepal
Ovary
Encloses and Protects Bud
Female part
Produces egg

10. Pollination and Fertilization in a Flower
Mature Pollen Grain
Sperm Cells
Tube Cell Nucleus
1. pollen grains land on stigma
2. pollen tubes grow down stigma to ovary
3B: Fusion of 2nd sperm + two polar nuclei
Stigma
3. double fertilization
Style
Sperm
3A: Fusion of sperm + egg
Pollination and Fertilization in a Flower
Ovule
Polar nuclei
Ovary
Egg
