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.
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
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 >
Shade gardens are often good locations to plant annuals such as begonias, coleus and impatiens, all of which love shade, reports Lowe's. Additionally, there are a wide variety of plants and shrubs, most of which are known more for their foliage than their flowers, are capable of thriving in the shade.Full Answer >
It has been proven that coffee and coffee grounds make plants grow faster. However, no one is certain whether the growth has anything to do with caffeine or if the other ingredients found in coffee are responsible.Full Answer >
Ideal conditions for a plant will vary by species. For example, the soggy soil that would kill a cactus is a must for bog-loving plants like Venus flytraps.Full Answer >
