Show how water is necessary for …

Water is very necessary for photosynthesis. An experiment to show water is necessary for photosynthesis is given below:

Every plants need water for photosynthesis to make their food(glucose ). Plants absorb water through their roots. Then from roots, by their special part called xylem, water is taken up to their leaves where photosynthesis occur. Then from leaves food is distributed to different parts of the plant. So like that if plants do get water then there could be no more food produce and if there would be no more food produce then it means that there would be no more process called photosynthesis. So water is very important for photosynthesis.

(i) Water is used to transport the metabolic products from one part to the other where they are needed. So it acts as a vehicle for the transportation.
(ii) water is an electron source of photosynthesis.In this process six water molecules combine with six carbon molecules to form, oxygen and glucose.
(iii) Water is evaporated through the stomata present on the leaves. It cools the plant in the hot sunny days.
(iv) Water is necessary to maintain turgidity i.e. the pressure of water in the cells of plants which is important for the survival of plant else it will wilt. It is also required for the growth as it expands the plant cells.
(v) Water regulates the opening and closing of stomata, which in turn regulates transpiration and photosynthesis.
