Photosynthesis Big Ideas

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

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

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

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

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

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

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