Final answer:
The purpose of vascular tissue in plants is to move water, food, nutrients, and materials dissolved in water, hence the answer is e. All of the above.
Step-by-step explanation:
The main purpose of vascular tissue in plants is to transport various substances throughout the organism. The two primary types of vascular tissues are xylem and phloem. Xylem is responsible for the movement of water and dissolved minerals from the roots to the rest of the plant. On the other hand, phloem transports sugars and other metabolic products throughout the plant, mainly from the sites of photosynthesis to where they are needed for growth, storage, or consumption.
The correct answer to the student's question is e. All of the above, which includes water, food, nutrients, and water-soluble materials that are transported by the vascular tissue in plants.
