In the Chloroplasts

• 1. Thylakoid
• -Contains Chlorophyl
• -Site of Light Dependent Reaction

6
In the Chloroplasts

• 1. Stroma
• -Site of Light Independent Reaction

7
Light Dependent Reactions

• 6H2O 6CO2 ? 6O2 C6H12O6
• Where in the chloroplast?
• -Thylakoid
• When light strikes the leaf
• Split?
• -H2O
• Released?
• -O2 Gas
• 6H2O 6CO2 ? 6O2 C6H12O6

8
Light Independent Reaction

• Where in the chloroplast?
• -Stroma
• Splits?
• CO2
• Formed
• Glucose (C6H12O6)
• 6H2O 6CO2 ? 6O2 C6H12O6

11
What is the Independent Variable?What is the
Dependent Variable?
IV Water Temperature
DP of Clams
12
Most Photosynthesis takes place in what layer of
the leaf?

• Palisade Mesophyll

13
The correct order of cellular respiration is
Glycolysis, Krebs Cycle, Electron Transport Chain
14
Reactants of cellular respiration/Products of
photosynthesis.
Glucose and Oxygen
15
A reaction in the presence of oxygen is
considered to be
Aerobic
16
Glucose is the building block for what
biomolecule?
carbohydrate
17
The anaerobic process muscles use to make energy
when deprived of oxygen is
Lactic Acid Fermentation
18
Glycolysis occurs in the
cytoplasm
19
The step of respiration that produces the most
ATP is
Electron Transport Chain

• Xylem in
• -Water in
• Phloem out
• -Glucose out

21
In the Xylem

• Water is absorbed in the
• Roots
• Water travels from the roots to the
• Stem
• Water travels from the stem into the
• Leaf
• For Photosynthesis

22
In the Phloem

• Glucose is made in the
• Leaf
• Exits the leaf to the
• Stem
• Stored in the
• Roots

23
Types of Roots

• Fibrous Roots
• -Many branching roots
• -help prevent soil erosion
• -absorb water quickly
• Taproots
• -grows long and thick
• -absorb water deep in the soil

28
Types of Stems

• Herbaceous Stems
• -green (contains chlorophyll) able to.
• -Photosynthesize
• Woody Stems
• -ex. Trees.Have rings
• Modified Stems
• -ex. Tubers (potatoes), rhizomes, bulbs, and
  corms

29
What type of stem?
Herbaceous
