Photosynthesisand respiration By Jessica Thole
What is photosynthesis? • Photosynthesis is • the process by which plants turn raw materials into food
Steps to photosynthesis • Step 1 • CO2 enters leaf or stomata • step 2 • H2O enters root system • step 3 • Sun causes a chemical • change: glucose • Step 4 • inside leaf plant makes food • Step 5 • O2 is released
What is respiration? • Plants are self-sufficient. They make their own food thru the process of photosynthesis using light energy to make sugars from carbon dioxide (C02) and water (H20).
