Introduction:
In plants, there are different types of tissues that perform various functions. One of the most important tissues is vascular tissue, which includes xylem and phloem. These tissues are responsible for the transport of water, minerals, and nutrients throughout the plant.

Explanation:
Xylem and phloem are both types of vascular tissues found in plants. They are located in the stem, roots, and leaves of the plant and are responsible for the transport of substances essential for the plant's growth and survival.

Xylem:
Xylem is a complex tissue that primarily transports water and minerals from the roots to the other parts of the plant. It consists of various types of cells, including tracheids, vessels, fibers, and parenchyma cells. Tracheids and vessels are long, tube-like cells that form a continuous pathway for water movement. They are dead cells and have thick walls that provide strength and support. The movement of water in xylem is primarily driven by transpiration, which is the loss of water from the plant through small openings called stomata.

Phloem:
Phloem, on the other hand, transports organic nutrients, such as sugars and amino acids, from the leaves to the other parts of the plant. It consists of sieve tube elements, companion cells, fibers, and parenchyma cells. Sieve tube elements are specialized cells that form a continuous tube-like structure for the movement of organic substances. They are living cells and are connected end-to-end through sieve plates. Companion cells are closely associated with sieve tube elements and provide metabolic support.

Vascular Tissue:
Xylem and phloem together make up the vascular tissue of plants. This tissue is responsible for the long-distance transport of water, minerals, and organic nutrients. Xylem transports water and minerals from the roots to the leaves, while phloem transports organic nutrients from the leaves to the rest of the plant. The movement of substances in the vascular tissue occurs through a process called translocation.

Conclusion:
In conclusion, xylem and phloem are the two main components of vascular tissue in plants. They play a crucial role in the transport of water, minerals, and organic nutrients, which are essential for the plant's growth and survival. Therefore, the correct answer to the given question is option 'C' - vascular tissue.

Because xylem are transport the water and nutrients to all body parts of the plant and phloem are transport the food to all body parts of the plant
