Life Abounds Photosynthesis http://quest.arc.nasa.gov/projects/astrobiology/astroventure/index.html

Today’s Objectives By the end of today, you will be able to: recognize that all consumers directly or indirectly eat green plants. explain the process of photosynthesis

Lesson 5—Photosynthesis What do plants need for photosynthesis??? Sunlight Carbon Dioxide Chlorophyll/Chloroplasts Water Clipart

Lesson 5—Photosynthesis SUNLIGHT and Chlorophyll Absorbed by the chlorophyll in the leaves of plants Chlorophyll interacts with sunlight to split the water in the plant into its basic components Provides energy that drives photosynthesis Artificial light can be used to drive process as well Clipart

Lesson 5—Photosynthesis WATER Transported through plants in tubes called xylem CO2 combines with water in chloroplasts to begin synthesis (making of) sugars Water is split into its hydrogen and oxygen parts, and oxygen is released Clipart

Lesson 5—Photosynthesis CARBON DIOXIDE Co-dependency between plants and animals! Carbon Dioxide enters the leaves through stomata Plants take in CO2 and release O2 Plants will also release water through the process of transpiration Clipart
