Hypothesis- The distribution and growth of grass are influenced by slope, water, and sunlight.
Theoretical basis of my research project
Although this might vary based on the overall topography of the entire area, water naturally tends to accumulate near the foot of a slope while the top stays drier. For optimal results, plant water-loving, cold-hardy plants toward the bottom of your slope and drought-tolerant, sun-loving plants toward the top.
Water facilitates the movement of vital nutrients through a plant. Plants take up and utilize nutrients from the soil. Water keeps a plant erect because it prevents the plant from drooping in the absence of enough water in the cells. Sugar and other dissolved nutrients are transported through the plant by water. Thus, in addition to being undernourished, the plant becomes physically feeble and is unable to sustain its own weight in the absence of the right water balance.
All green plants need photosynthesis to function because it turns light, carbon dioxide, and water into glucose, a sugar that is the major source of energy for plant development and upkeep. Plant cells contain structures called chloroplasts that contain chlorophyll and are where the process of photosynthesis occurs. The green pigment called chlorophyll absorbs sunlight and converts it into glucose and oxygen (O2), which is released as a byproduct. Photosynthesis efficiency is contingent upon the quality and intensity of light that a plant receives. To optimize photosynthesis and foster growth and development, plants require an adequate amount of sunlight. Reduced growth rates and poor plant health can result from little sunlight.
Keywords for Publication- The three keywords that will describe my research project are the water gradient, slope gradient and exposure to sunlight.
A good start to ideas that could go in your introduction. Keep in mind that different plants have different tolerances for either sun / shade and it is not a simple relationship between sun and growth for plants in general.
