Answer 1

            
                                                   Stroma    
                                                =========          

Stroma is seen in leaves of plants inside the chloroplast as its cytoplasm. Stroma is a fluid which consists of grana, thylakoids and other enzymes necessary for photosynthesis.

                                                  Photosynthesis
                                                =============

The process of preparation of food by plants with the presence of water, sunlight, carbon dioxide, chlorophyll, etc....

                                                     Chlorophyll
                                                     =========

The green pigment present in the surface of leaves which is essential for photosynthesis as it obtain sunlight for photosynthesis.

                                            Photolysis in water
                                           ===============

Photolysis of water means molecules splits into component when light strikes. 

Equation for photolysis follows, 

$H2O ----\ \textgreater \ H+ + Oh-  ; 2OH ----\ \textgreater \ 2H+ + O2$
