essay on water and plants
Answers
Answer:
Water is a vital component to the survival of every plant in the world as it is aids in the way that they obtain their food (through the process of photosynthesis), grow (cell division, mitosis), respire (cellular respiration) and how they keep their formation (rigidity). Water helps plants maintain their formation by transporting dissolved nutrients, amino acids and sugars from the soil to areas where it is of high demand. It flows through cell membranes from an area of high concentration to an area of low concentration (osmosis) (A Sanders, 2010). Water allows plants to survive by being one of the vital reactants in the chemical reaction of photosynthesi

Every molecule of water contains two hydrogen atoms and one oxygen atom which are tightly held together by covalent bonds. This molecule contains 10 protons, 10 electrons and 8 neutrons (refer to fig 6) (Answers Cooperation, 2010). Water has a boiling point of 100°C and a freezing point of 0°C. In our world water is found in three different states; ice, liquid and as steam or water vapour. Due to cohesive forces, the molecules of water are strongly attracted to each other and therefore the surface tension (the charge of the water molecules attract eachother to form a ‘skin’ across the surface of the water) that is created is vital to the survival of many animals (e.g. pond skater). Water molecules have dipoles due to the electrons being shared from both hydrogen atoms to the oxygen atom (refer to fig 6). This means that the electrons spend more time near the oxygen atom then near the hydrogen atoms resulting in a slight negative charge on the side of the molecule which contains the oxygen atom and a slight positive charge on the side of the molecule which contains both hydrogen atoms
