A. assemble amino acids
Mycorrhizae are fungal colonies that are in a mutualistic relationship with plants. These fungi help the plant absorb more nutrients and water from the soil, while the plant provides the fungus with carbohydrates that it generates through the process of photosynthesis. Mycorrhizae do not carry out the assimilation of amino acids, this is a process carried out the plant by itself.

On a graph of temperature vs. time, it shows pure substances exhibit a sharp boiling point and a sharp melting point as a horizontal flat line wherein the temperature does not change over time up until all the pure substances boiled or melted. The temperature stays stable at 160°C between 4 minutes and 11 minutes. This horizontal flat line part of the graph is normal of a pure substance. The melting point of a solid substance is usually used to specified if the substance is pure. Likewise, the boiling point of a "liquid" substance can be used to specify if the substance is pure as well.
