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)

4 Pistol (female) Stamen (male) Petal Stomata Chloroplast Leaves Stem Roots Phloem Xylem Food Storage Bulb

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
