  2. Basic Description In every plant, water moves from the ground, through the roots, up the stem, enters the leaves, and finally exits from the plant through the leaves. The roots are covered in fine root hairs. The stem contains a tube known as the xylem. The leaves use the water to make energy. There are openings called stomata in the leaves to allow the water to escape.

  3. WHATactuallyhappens ? Water enters the ground when it rains and moves through the Earth in the direction of the fine root hairs. Because the hairs are so fine they can easily absorb water through a process known as osmosis. Osmosis describes how an area of high concentration of water moves to an area of low concentration. This fact is true for all cells in animals, as well as plants.

  4. WHATactuallyhappens ? If there is water in the ground, it will move in the direction of the roots. Because there are thousands of tiny root hairs they are able to absorb the water easily and allow it to start its journey through the plant. From the root hairs, the water drop enters the roots and continues to move by cohesion.

  5. Cohesion Cohesion means sticking together, and water drops stick together as they move through the plant. The force which makes the water move is caused by transpiration, which means that because of the effects of heat, humidity, or strong winds, water escapes through the stomata in the leaves. This causes water to evaporate into the atmosphere and to pull more water up the stem.

  6. BenefitsofWater Firstly, water allows a plant to take in minerals from the soil. Plants need minerals to help them grow. Secondly, water gives shape and rigidity to the leaves so that if there is not enough water for the plant, it’s leaves begin to wilt. Finally, water is used in the leaves to make energy through the process of photosynthesis.

  8. Photosynthesis Plants are the only organisms which can make their own food. In the leaf, water combines with energy stored from light and carbon dioxide in the chloroplast to make glucose or starch. This is the food for the plant.

  9. Photosynthesis Equation carbon dioxide +water(+ light energy) → glucose +oxygen = 6 CO2+6 H2O →C6H12O6+6 O2

  10. What Next ? After photosynthesis takes place, the plant has energy in the form of glucose and starch, but it also has extra water and oxygen. On the under side of a leaf, there are small openings called stomata. These let water out and carbon dioxide in. The water is moved out of the leaf, into the atmosphere by the process of respiration.

  11. Respiration The respiration takes place all the time but photosynthesis only takes place in the day. Some of the water is kept inside the plant to move the glucose or starch around, through tubes called the phloem. As water exits the leaves, new water is drawn up the stem and into the leaves to be used for photosynthesis again.
