A mycorrhiza is a mutualistic relationship between fungal hyphae and the roots of true plants. The fungal hyphae increase the absorptive surface area of the roots of the plant by aiding in the absorption of water, phosphorus, and other mineral ions from the soil to the roots of the plant. The plant is photosynthetic and provides the fungus with carbohydrates. An experiment was conducted to determine the effect of mycorrhizal associations on plant growth. Two groups of plants were grown. One group was planted in soil that had been sterilized. The other group was planted in the same type of soil, but the soil had not been sterilized. All other factors remained the same between the two groups. The plants were allowed to grow for 8 weeks. Each week, the height (in centimeters) of each plant was measured. The picture below shows the plants after 8 weeks of growth. The data table provides quantitative data on the growth of the plants over the 8-week period.
