Answer 2

a) Leaves prepare the food by the process of photosynthesis .

by this equation :-

CO2 + H20 in the presence of CYTOPLAMS and SUNLIGHT it produce C6H12O6 (glucose) .

and this is food for a plant .

● ROOTS UTILISE it by producing themselves to reach to the near water .

b) WAter is absorbed by the ROOTS HAIR and then it went up to the leaves by PHOLEM .

● Leaves lost extra water through the stomata which open themselves due to extra water in plats leaves .

THIS PROCES IS ALSO CALLED photosynthesis .
