                        Transpiration    Requirements  :  1 - Bottle  2 - Oil 3 - Water 4 - Bled  5 - Marker 6 - Leaf with petiole of Colocasia esculenta Method  :  1 -  A leaf with petiole of Colocasia esculenta   cut from the plant . 2 - I filled a bottle with water. 3 - I dipped some part of petiole in bottled water. 4 - I put the oil on the top of the bottled water in such a way that a layer of the whole oil falls on the to. 5 - Then I put a mark on the bottled water. Observation  :  After 10 hours it was noticed that the leaf was slightly bent and the water level in the bottle was slightly reduced.           Then I again marked the water level of the bottle . Inference  :  It was seen that no part of the bottle was evaporated by it, only the leaf.        So, it proved that transpiration takes place t...

      Xylem is the path of water conduction Requirements : 1 - Bottle  2 - Lequid Red colour 3 - Bled  4 - Stem with leaves of  Syngonium podophyllum 5 - Water Method :   1 - First I filled the bottle with water. 2 - Then i mixed some liquid red color in the water. 3 - Then I noticed that the whole water was red. 4 - Then I put the stem with the leaf of Syngonium podophyllum tree in the bottle in such a way that the leaf is on the mouth of the bottle. 5 - In this way I left the bottle for 12 hours. Observation :  After 12 hours the stems turned red and the leaves turned light red. Inference :  The stems and leaves turn red because the red water in the bottle has reached the stems and leaves through the xylem vessels .             So, it is proved that Xylem is the pathway of water conduction.                            Experiment was...
