3 TARGET GROUP 11Yrs.-14Yrs. 6 th -8 th AGE CLASS BACKNEXT

4 AFTER INTERACTIVE WITH THIS SOFTWARE THE LEARNER WILL BE ABLE TO : DEFINE AUTOTROUGH DRAW A DIAGRAM TO EXPLAIN THE PROCESS OF PHOTOSYNTHESIS. IDENTIFY THE PRODUCT OF PHOTOSYNTHESIS. WHICH PART IS KITCHEN OF PLANT. APPRECIATE THE ROLE OF PLANT IN LIFE. BACKNEXT

5 CONTENTS WHAT ARE AUTOTROUGH.AUTOTROUGH. PHOTOSYNTHESIS. ELEMENTSELEMENTS OF PHOTOSYNTHESIS. ABSORPTION OF CARBONDIOXIDE.CARBONDIOXIDE. PRODUCTION OF OXYGEN BY PLANTS.OXYGEN BY PLANTS. IMPORTANCEIMPORTANCE OF PLANTS. BACKNEXT

9 Carbon Dioxide is colorless, odorless, and slightly acid- tasting gas is used by plant for making their food.Plant absorbed CARBONDIOXIDE gas from atmospher through STOMATA in day time. BACKHOME NEXT

10 SOIL POT PLANT ROOT CO2 GAS SUNRLIGHT EXPERIMENT OF PHOTO SYNTHESIS CHLOROPLAST BACKHOME NEXT

11 PRODUCTS OF PHOTOSYNTHESIS 1. CARBOHYDRATES 2. OXYGEN GAS BACKHOMENEXT

12 Chloroplasts, minute green, spherical structures, are essential to the process of photosynthesis, in which captured sunlight is combined with water and carbon dioxide in the presence of the chlorophyll molecule to produce oxygen and sugars.

13 This electron microscope image of raw cane sugar reveals the shape of sugar crystals. CARBOHYDRATE CARBOHYDRATE GROUP CONSIST OF PRINCIPALLY OF SUGER,STARCH, CELLULOSE etc.THE MOLECULER FORMULA OF SUGER IS C 6 H 12 O 6 BACKHOME NEXT

14 ELEMENTS OF PHOTOSYNTHESIS WATER CARBON DIOXIDE SUN LIGHT GREEN LEAFY PLANT BACKHOMENEXT

15 PHTOSYNTHESIS IS: THE PROCESS BY WHICH THEGREEN LEAF OF PLANT MAKE THEIR OWN FOOD BY TAKING WATER FROM SOIL CARBONDIOXIDE FROM AIR AND IN PRESENCE OF SUN LIGHT. BACK HOME NEXT 6CO 2 +6H 2 O=C 6 H 12 O 6 +6O 2

17 PRODUCTION OF OXIGEN IN PHOTOSYNTHESIS WATER BEAKER LEAF FUNNEL TESTTUBE OXIGEN BUBBEL OXIGEN GAS SUNRAYS BACKHOME NEXT

18 REQUIREMENT FOR THE EXPERIMENT OF SHOWING PRODUCTION OF OXYGEN IN PHOTOSYNTHESIS. AQUATIC PLANT. BEAKER FUNNEL TESTTUBE BACKHOME NEXT

19 Photosynthesis, uses atmospheric carbon dioxide and water as building blocks. Organisms that have lost the ability to photosynthesize obtain their carbon indirectly, from plants that are able to photosynthesize. A by-product of photosynthesis is oxygen, necessary to almost all plants and animals to maintain life. Organisms that breathe in oxygen, exhale carbon dioxide. BACK HOMENEXT

20 BACKHOMENEXT IMPORTANCE OF PLANTS. PLANTS GIVES US OXYGEN GAS. PLANTS REDUCE CARBONDIOXIDE LEVEL IN ATMOSPHERE. PLANTS GIVES US FOOD.

21 PLANTS ARE LIVING OBJECTS. PLANTS NEED FOOD. PLANTS MADE THEIR FOOD THEMSELF. SO PLANTS ARE AUTOTROPH. AUTOTROUGH ARE: BACK HOMENEXT
