Plants need water to grow because plants require internal water pressure to strengthen the stems and leaves, and plants need water to create energy. Water is also necessary for photosynthesis, which occurs in the plant's leaves with water from the stem.Know More
All living things need water to grow. Plants are made up of about 90 percent water and therefore require more water than animals. Water pressure inside a plant is called turgor. Without turgor, the plant wilts and dies. The internal water pressure is created when the plant absorbs water from the ground, up through the stem, to the leaves. The water is needed to create a skeleton for the plant so the plant can remain upright.
Once the water reaches the leaves, photosynthesis occurs during the daylight hours. During photosynthesis, the plant creates food. Without water, the plant could not create the sugar it needs for energy. Water travels up the stem to the leaves, and there, the water is exchanged for carbon dioxide during transpiration. This natural process only occurs when sunlight is present. Transpiration also serves to cool down the plant, much like sweating cools a human being. The water exits the leaves through small holes called stomata.Learn more about Botany
Plants grow fastest when they get the proper amount of light, water and soil. How a plant thrives is dependent on the species, whether they are placed inside or outside.Full Answer >
Respiration, in which energy is released from carbohydrates for metabolic needs, takes place in plants through a process which can be expressed in a word equation as: glucose + oxygen = energy + carbon dioxide + water. The chemical equation for this process can be expressed as: C6H12O6 + 6O2 = energy + 6CO2 + 6H2O. Respiration, which is a breaking-down process that releases energy, can be viewed as the opposite of photosynthesis, which is a building-up process that takes in energy in the form of light and uses it to produce carbohydrates.Full Answer >
Water lilies grow from a tuber underneath the water. As the plants grow, the stems and leaves break the surface of the water, and the blossoms begin to float. A person is able to grow water lilies in a tub at home as well.Full Answer >
Some of the plants found in the Indian Ocean are species of mangrove trees in Madagascar's mangrove forests, India's coastal sea grass and West Australia's macroalgae. The Indian Ocean covers a variety of biologically diverse ecological regions, including Africa's eastern shores, western Australia and the southern coastlines of Asia.Full Answer >
