1. Copy Words (not diagram) in Journal and answer question Provide evidence for your answer
Extra CO2 in blood causes pH to decrease (more acidic). Extra CO2 can be caused by mitochondria making more ATP like when you are exercising. Breathing more lets you remove excess CO2 and then lower your blood pH. Positive or Negative Feedback?

2. Today’s Agenda Silent Reflection 3rd Only – Finish Lab Station
Plant Notes

3. Intro Questions Where in the plant does the most photosynthesis occur?
How does the water get to where the photosynthesis occurs?
How does the CO2 get in?
What happens to the sugar that gets created?
Where does the oxygen created go?
Could do a venn diagram for systems. Circulatory Skeletal System Respiratory Reproductive Integumentary Immune System

4. Plant Body Shoot system
Organs: Leaves, Stem, Reproductive Structure (Flower)
Above ground (usually)
Many functions including:
photosynthesis
reproduction & dispersal
transport

5. Plant Body Root system Organ: Root Underground (usually)
Anchor the plant in the soil
Absorb water and nutrients
Conduct water and nutrients
Food Storage

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

7. Vascular Tissue Xylem Phloem
Transports water and dissolved nutrients UP the plant
Nitrogen, Phosphorus, Potassium, Calcium, Sulfur, Boron, Magnesium, Chlorine, Manganese, Iron, Zinc, Copper, Molybdenum, Nickel
Why?
Phloem
Transports sugars down the plant
Why?

8. Dermal Tissue Transpiration – Plant Water Loss Through Evaporation
Outer covering
Single layer of cells
Cuticle – waxy coating
Trichomes – protective hairs
Root Hairs
Guard Cells
Transpiration – Plant Water Loss Through Evaporation

9. Stoma = opening in the leaf for gas exchange, water evaporation
Conserves water
Photosynthesis
Transports water and sugar to stem and roots
Stoma = opening in the leaf for gas exchange, water evaporation
Structures of the Leaf

12. 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)

13. 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

14. 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

15. Applying Your Knowledge
