The vessels that transport water and minerals in plants are called xylem. The xylem is one of the two types of transport tissues found in plants, the other being the phloem. The xylem tissue is responsible for the transport of water and minerals from the roots to the rest of the plant.
Xylem tissue is composed of several different types of cells, including tracheids and vessel elements. These cells are dead at maturity and have thick walls containing a substance called lignin, which provides strength and support to the tissue.
The transport of water and minerals in xylem occurs through a process called transpiration. Transpiration is the loss of water vapor from the leaves of the plant through small openings called stomata. As water is lost from the leaves, it creates a negative pressure or tension in the xylem vessels, which pulls water up from the roots.
The movement of water and minerals through the xylem is mainly due to two physical properties: cohesion and adhesion. Cohesion is the attraction between water molecules, while adhesion is the attraction between water molecules and the walls of the xylem vessels. These properties allow water to form a continuous column within the xylem, allowing it to be transported upwards against gravity.
In addition to water and minerals, the xylem tissue also transports certain substances, such as hormones, that are produced in the roots and need to be transported to other parts of the plant.
In summary, the vessels that transport water and minerals in plants are called xylem. The xylem tissue is composed of different types of cells, including tracheids and vessel elements, and it is responsible for the upward transport of water and minerals from the roots to the rest of the plant. This transport occurs through a process called transpiration, and is facilitated by the physical properties of cohesion and adhesion.
