Xylem tissue is mainly concerned with the

The correct answer is: B. Transport of water and mineral nutrients in plants.

Xylem is a type of plant tissue that is responsible for the transport of water and mineral nutrients from the roots to the leaves. It is made up of long, dead cells that are arranged in tubes. The cells are filled with a substance called xylem sap, which is a mixture of water and minerals. Xylem sap is transported up the plant by a process called transpiration. Transpiration is the process by which water evaporates from the leaves of plants. As the water evaporates, it creates a vacuum that pulls the xylem sap up the plant.

The other options are incorrect because:

• Photosynthesis is the process by which plants use sunlight to create food. It takes place in the leaves of plants.
• Storage of prepared foods in plants is the function of phloem tissue. Phloem is another type of plant tissue that is responsible for the transport of food from the leaves to other parts of the plant.
• Transport of enzymes in plants is not a specific function of any type of plant tissue. Enzymes are proteins that are involved in many different processes in plants, including photosynthesis, respiration, and digestion.
