Match-

1. Irrigation → Sprinkler

2. Alexander Fleming → Antibiotic

3. PVC → Thermoplastic

4. Sodium → Kept in kerosene

5. Living material of cell → Protoplasm

6. Aluminum → Wrapping food

7. Fertilized egg → Zygote

8. Cell wall → Plants

9. Wildlife sanctuary → Panchmarhi

10. Fire extinguisher → Carbon Dioxide

( a ) Irrigation is the process of supplying required amount of water to the crops and plants.There exists modern methods of irrigation and traditional methods of irrigation. Sprinkler system is the type of modern method of irrigation,thus Irrigation → Sprinkler.

( b ) Alexander Fleming discovered penicillin which is an antibiotic. Pencillin is made from penicillium which is a fungi.Thus,Alexander Fleming → Antibiotic

( c ) Thermoplastics are those plastic that can be moulded and heated again after it used to any substance.PVC is the type of thermoplastic and it can be moulded and can change its shape when heated again.Thus,PVC → Thermoplastic.

( d ) When sodium is kept freely,it reacts vigorously with air. Potassium and sodium both reacts vigorously with air. That's why they are kept is kerosene. Thus,Sodium → Kept in kerosene.

( e ) Living material of cell → Protoplasm .Protoplasm is living material of the cell.It was discovered by Dujardin and he named it "sarcode".

( f ) Aluminium which is used in making aluminum foil that is used for wrapping foods.As aluminum don't react with food, either the food is acidic or basic.We use it as food wrapper.Thus,Aluminum → Wrapping food

( g ) The fusion of a male gamate and female gamete is called fertilization to form zygote.Zygote is single cell which contains one nucleus. Thus,Fertilized egg → Zygote.

( h )Cell wall is present only in plant cells,it provides a fixed shape to the cell. Cell wall is non-living component .Thus, Cell wall → Plants.

( i ) Wildlife sanctuary is a protected land that is created/made for the protection of wild animals . Some wildlife sanctuaries are Gandhi wildlife sanctuary,Bharatpur bird sanctuary,panchmarhi etc .Thus, Wildlife sanctuary → Panchmarhi

( j ) Carbon dioxide is used as fire extinguisher because carbon dioxide is heavier than oxygen encloses the combustible substance land cuts off the supply of oxygen to the combustible substance,which extinguishes fire. Thus,Fire extinguisher → Carbon Dioxide
