In this experiment, we test to see how differently the pea plants grow when one plant has fertilizer, one plant has rice, and one plant has nothing. We are also testing to see how the sun affects the growth of the peas by having more plants with the substances in them in the sun. In order to carry out this experiment, one must understand what a pea plant is, the life cycle of a pea plant, what fertilizer is, and how fertilizer affects the plant. Pea plants are plants with small, flowers and long green pods that have green seeds that are edible. Plants are living organisms, that usually grow in a permanent site, and absorb inorganic substances and water through its roots. Plants create nutrients with photosynthesis. Photosynthesis is the process when chlorophyll converts sunlight and carbon dioxide into sugar, which the plant will use for energy. Fertilizer is a natural or chemical substance that adds nutrients to a plant to affect its fertility. The fertilizer we are using is 14-14-14. The first number is the amount of nitrogens in the fertilizer, the second number is the amount of phosphate and the last number is the amount of potassium. Plants can’t without nitrogen, phosphorus, and potassium. Within the cells of a plant, there are certain chemical metabolic reactions that deal with reproduction and growth. The plant depends on the nutrients in the soil in order for these chemical metabolic reactions to happen.Pea plants go through multiple phases while growing. Pea plants start off as nothing more than a seed. That seed needs warmth and water in order for the outer shell to soften and the roots to start growing and taking in nutrients from the soil. While the roots start to grow, small shoots are also forming upwards, towards the surface of the soil. Then tiny leaves begin to unfold and begin photosynthesis, so the growing pea plant has food. While the plant is growing, it sends out tendrils, a specialized stem with a threadlike shape, used to attach to things such as trellis’ or fences, to keep itself up. Flowers then grow, with both male and female reproductive organs. Pea plants are self-pollinating meaning that the pollen drops from the anthers onto the stigma. Pea plants do not depend on any outside forces to help them pollinate. As soon as the pea plant self pollinates, it begins to fertilize. The pollen travels down the inner tube of the style to the ovaries of the plant. The pollen fertilizes the ovules, which become the seeds. The flowers will then wilt and the ovaries will begin to swell to protect future seeds. Plants that have flowers and produce seeds within a carpel are called angiosperm. A carpel is the female reproductive organ in a plant. I hypothesize that the pea plant with the fertilizer in the sun is going to grow the tallest. I hypothesize this because fertilizer provides plants with extra nutrients that they need and the sun gives the plant more energy by turning the light into food for itself, through photosynthesis. While pea plants can fix nitrogen from the soil, meaning their fertilizer requirements are fairly low, I believe that if we put too much fertilizer in the pea plant that it will not help the plant grow, but hurt it.
