The most abundant element present in the plant is :-The organic compounds that make up the body of a plant (carbohydrates such as cellulose and starch, proteins, lipids and nucleic acids) are all built on a carbon skeleton.
Carbon, obtained from atmospheric $CO_2$ through photosynthesis, makes up about 45 percent of the dry weight of a plant, followed by oxygen and hydrogen.
Nitrogen is the most important mineral nutrient taken up from the soil, but its share is only about 1–4 percent of dry weight. Manganese and iron are micronutrients needed in very small amounts.
So the most abundant element present in the plant is carbon.
