Vascular tissue is essential for the transportation of water, nutrients, and food throughout the plant. The two main types of vascular tissue are xylem and phloem.

Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, primarily upward. It contains specialized cells that facilitate this process and helps support the plant structure through lignin, which strengthens cell walls.

Phloem, on the other hand, transports the products of photosynthesis, such as sugars, from the leaves where they are produced to other parts of the plant where they are needed or stored. This process is often referred to as translocation.

Together, xylem and phloem constitute a vascular system that is crucial for maintaining plant vitality, as they enable the distribution of essential resources necessary for growth and development. Other options like stomata and chloroplasts, roots and stems, or leaves and flowers refer to different plant structures or functions but do not pertain to the vascular tissues responsible for transportation.
