e Science Labs Lab 16: Plant Transpiration Pre-Lab Questions When did vascular plants evolve? How was this timeline uncovered? 2 How does a vascuiar system help a piant to grow bigger? 3 Discuss how gas exchange aftects transpiration Draw a diagram to iustrate your answerst 4 Why is water referred to as the "universal solvent? 5 Why is a water droplet not shaped ike a sphere? 6 In essay form, discuss three adaptations plants have made to thrive in different environments O eScience Labs, LLC 201

Explanation / Answer

The vascular plants are evolved during Silurian period in palaeozoic era .it was uncovered because it’ is placed under Carboniferous period but as per the research on fossil plants it was placed under Silurian period The circulatory system in plants as in animals is vascular system . Mainly it consists of xylem and phloem . These gives more nutrients as it grows bigger such away the plant vascular system was evolved .xylem tranports water from roots through out the plant. They may die after one year and replaced by New cells where as phloem will transport food from the leaves where photosynthesis takes place. These are always alive Exchange of gases takes place at the stomatal pores opening . While they are in opened condition the water Vapour moves outside and carbon dioxide moves inside .so, theoretically as the stomata opens the rate of transpiration increases Water can dissolve a wide variety of substances .so, called good solvent. It is called universal solvent because,it dissolves more different substances than any other liquid.it is also very important to every living thing on the earth According to my knownledge the water droplet is sphere in shape due to the internal surface tension inside the water droplet
