How do scientists summarize the process of photosynthesis?

plants need photosynthesis to produce their own food,co2 enters air spaces through the stomata,this co2 enters cobines with H2O,light energy splits H2O molecules,H2O enters from xylem vessels,light is absorbed by pallisade,spongy,mesophyll and gaurd cells by chlorophyll,carbohydrates and oxygen are produced as by products
