Final answer:
Roots are responsible for the absorption of water and minerals, providing anchorage, and storing carbohydrates. However, the process of making food, or photosynthesis, occurs in the leaves, not the roots.
Step-by-step explanation:
Roots are crucial to a plant's ability to take up nutrients and water from the soil via thin-walled epidermal cells and root hairs. Additionally, roots play a significant role in anchoring and supporting the plant. They allow plants to be firmly attached to the ground and grow tall without toppling over. In terms of storage, the ground tissues in roots can store the carbohydrates produced by leaves through photosynthesis. However, one function that roots do not perform is making food. This process takes place in the leaves of the plant through photosynthesis, which involves the conversion of light energy into chemical energy. Therefore, the correct answer to the question is that roots usually do not have the function of making food.
