Water makes up 80-95% of the mass in plant tissues. Transpiration is the loss of water from plants in vapor form. 95% of the water is absorbed from the soil for transpiration and 5% is absorbed during photosynthesis for producing necessary carbohydrates for growth. The rate of transpiration is dependent on the amount of water in which is available within the plant, soil, and on sufficient energy to vaporize water.
Hot, bright weather increases the rate of transpiration and creates risk for wilting if there is an inadequate amount of water available. Over time plants have adapted to tolerate weather conditions. Therefore If wilting takes place during hot, sunny days It Is possible for them to reheated over night when the temperate Is lower. However; If the solo dries without additional water from proclamation of Irrigation It Is possible for the plant to permanently wilt and soon after die.For optimal growth and quality of plants It Is crucial to manage and maintain the water status and irrigation based on the soil moisture the plant requires.
The Rhapsodies thaliana is a small flowering plant that is related to cabbage and mustard. It is one of the model organisms used for studying plant biology and the first to have its entire genome sequenced. The life cycle for these plants is extremely short, about six weeks from germination to seed maturation. The Rhapsodies is native to Europe, East Africa, Asia, and Japan.The Rhapsodies was first discovered in the Hard Mountains in Germany, 1577 by Johannes Tall. A key feature of the Rhapsodies plant Is that it's relatively small making It easy and inexpensive to grow them under a variety of research conditions.
Another key aspect of the Rhapsodies Is that It develops, reproduces, and reacts to disease and environmental tresses In ways comparable to many crop plants. Hypothesis and Objective: Does the amount of water affect the growth of Rhapsodies plants?Design of Experiment: Materials: - 8 Rhapsodies plants - Tap water - Ruler - Marker Procedure: the plants each week. The dependent variable is the growth amount of the plants. The growth will be determined by measuring the height and width of the plants each week.
The control group will receive no water over the 8 weeks. 2. There will be four different groups each containing two plants. The first group (also known as the control group) will receive no water, the second group will be watered once a week, the third group will be watered twice a week and the fourth group will receive water three times a week. . .
AL will be used consistently throughout the experiment every time a plant is watered. 4. The 8 pots will be placed in a location where they will each receive the same amount light exposure each day. 5. The growth of the plants will be recorded into the appropriate table below.
This number will be found by averaging the height growth of the two plants as well as the width growth of the two plants. The growth of the plants will be calculated every week for the next 8 weeks. 6. We will also be noting how the amount of water affects the overall appearance of the plant.We will do this by recording if there was an increase, decrease, or no change after each week.
7. Following the conclusion of the experiment, we will calculate the average growth of each plant over the entire 8-week period.
