- IT'S A PROCESS IN WHICH PLANTS MAKE FOOD
- GOOD MORNING STUDENTS . TODAY WE'LL LEARN ABOUT PHOTOSYNTHESIS . WHAT DOES PHOTOSYNTHESIS
- YES , PHOTOSYNTHESIS IS THE PROCESS IN WHICH AUTOTROPHS TAKE IN SUBSTANCES FROM THE OUTSIDE AND CONVERT THEN INTO STORED FORM OF ENERGY
- BUT WHAT ARE THE SUBSTANCES THAT AUTOTROPHS TAKE FROM OUTSIDE ?
- YOU SEE IN THE AIR THERE ARE MANY GASES AND FROM THAT GASSES THE PLANTS TAKE CO2 GAS AND WATER FROM RAIN OR WE USUALLY WATER THEM . THESE AUTOTROPHS ARE CONVERTED INTO CARBOHYDRATES IN PRESENCE OF SUNLIGHT AND CHLOROPHYLL
- WHAT DO CARBOHYDRATES DO ?
- CARBOHYDRATES ARE UTILISED FOR PROVIDING ENERGY TO THE PLANT
- THE CARBOHYDRATES WHICH ARE NOT USED IMMEDIATELY ARE STORED IN THE FORM OF STARCH
- MAAM HOW DOES PHOTOSYNTHESIS OCCUS ?
- SO IT OCCUR IN 3 STEPS1.ABSORPTION OF LIGHT ENERGY BY CHLOROPHYLL.2.CONVERSION OF LIGHT ENERGY TO CHEMICAL ENERGY AND SPLITTING OF WATER MOLECULES INTO HYDROGEN AND O23. REDUCTION OF CO2 TO CARBOHYDRATES
- IN THE END WE CONCLUDED THAT PHOTOSYNTHESIS IS A PROCESS BY WHICH GREEN PLANTS AND SOME OTHER ORGANISM USE SUNLIGHT , CO2 , WATER ETC TO MAKE THERE OWN FOOD LIKE GLUCOSE
- SO , WHAT DO WE CONCLUDE IN THE END ?
