Hint:
Xylem and phloem are the complex tissues. These are the conducting tissue in plants. Conducting tissues are those tissues which are responsible for transporting the materials from one part to another part of the plant. Xylem transports water and minerals whereas phloem transports food.
Complete answer:
Complex tissues are those tissues which are made up of more than one kind of cells and these different kinds of cells work together to perform a specific function. Hence they work as a single unit.
Xylem and phloem are the examples of conducting tissues.
Xylem is responsible for transporting the water and minerals from the root to the upper part of the plant. The movement of water and minerals is unidirectional. Because it translocates the water and minerals in one direction.
Components of Xylem:
Phloem is responsible for conducting the food material in a bidirectional manner. It transports the food from leaves to the other parts of the plant.
Components of phloem:
Note:
Xylem and phloem cells are not the examples of simple tissues. Because xylem and phloem are made up of more than one kind of cells and they work together to perform a single function. Simple tissues are remade up of one kind of cell and they perform the same functions.

Components of Xylem:
S.No. | Name of Xylem Component | Function |
1 | Tracheids | These are responsible for water conducting cells in non-flowering plants as well as flowering plants. |
2 | Vessels | These are present in flowering plants. These provide rigidity to the cell wall. |
3 | Xylem parenchyma | These are the living cells of xylem. These cells store food materials. |
4 | Xylem fibres | These fibres have thickened walls. These fibres provide the support to the plant |
Phloem is responsible for conducting the food material in a bidirectional manner. It transports the food from leaves to the other parts of the plant.
Components of phloem:
S.No. | Components of Phloem | Function |
1 | Sieve tube elements | These cells help in conducting the food from the leaves to the other parts of the plants. |
2 | Companion cells | These cells help in sieve tube cells for conducting the food material. They also help in maintaining the pressure gradient in sieve tube elements. |
3 | Phloem parenchyma | These cells store food materials. |
4 | Phloem fibres | These cells provide the mechanical strength to the plants. |
