Question

what do plant get rich of raw material from the photosynthesis

Answer 1

there are two raw materials needed by plant 
first one is 
WATER{H2O}:--- PANTS GET WATER BY THE ROOT HAIRS IN THE SOIL
CARBON DIOXIDE{CO2]::-- PLANTS GETS CO2 BY AIR WITH THE HELP OF STOMATA

Answer 2

Green plants make their own food by the process of photosynthesis. Chlorophyll, the green pigment found in chloroplasts, traps light energy from the sun. The plant also takes in raw materials from the environment, water through its roots and carbon dioxide moves into the stomata by diffusion.
