1. Photosynthesis Big Ideas

2. 7.5A  Recognize that radiant energy from the Sun is transformed into chemical energy through the process of photosynthesis
I can describe the energy transformation in photosynthesis
I can identify structures of a plant and their role in photosynthesis
I can identify the reactants and products of photosynthesis (name and formulas)
I can explain how photosynthesis fits in a food chain/web

3. Chemical Energy (needed to grow)
Photosynthesis…
Radiant Energy
AKA…
Solar Energy
Light Energy
transformed
Chemical Energy (needed to grow)

5. Plant Structures Transports WATER Transports FOOD/GLUCOSE
Xylem
Phloem
Stomata
Chloroplast
Roots
Leaves
Food Storage Bulb
Transports FOOD/GLUCOSE
Pore/hole that allows gas exchange (CO2 in and O2 out)
Plant cell organelle where photosynthesis takes place; contains chlorophyll – pigment that captures sunlight
Absorb water from the ground
Contain stomata for gas exchange
Plant stores food here until needed

6. Radiant Energy Chemical Energy
Chemical Equation: 6CO2 + 6H2O + Energy C6H12O6 + 6O2
Radiant
Energy
Chemical
Energy
Glucose (Sugar)
Carbon dioxide + Water + Sunlight Glucose (Sugar) + Oxygen

7. Photosynthesis Transforms Radiant Energy  Chemical Energy
Water + Carbon Dioxide sunlight Glucose (sugar) + Oxygen
H2O + CO2  C6H12O6 + O2
Reactants  Products
Chemical change b/c NEW substances are formed
Where? PLANTS LEAF Organelle: CHLOROPLAST

8. How photosynthesis fits into a food chain/web
All energy on Earth originates from the Sun
