Transport of Water and Minerals in Plants
Transportation is the process of movement of water and minerals to all parts of the plant body. Plants have a specialized system that enables them to distribute water and nutrients throughout their body. They use several processes such as translocation, absorption, storage and utilization of water.
Transportation in Plants:
The water and minerals are transported in plants by two types of conducting tissues:
- Xylem: The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves.
- Phloem: The phloem carries food downward from the leaves to the roots.
The three modes of transportation:
- Diffusion: The molecules in this system travel from a high-concentration region to a low-concentration region. This procedure does not necessitate the use of any energy.
- Facilitated diffusion: With the help of a carrier, usually a protein, the mechanism transports molecules from an area of higher concentration to a region of lower concentration. Because this process does not require any energy, it is referred to as a passive process.
- Active Transport: With the help of membrane proteins, this mechanism transports molecules from a lower to a higher concentration region. Because it requires ATP to function, this system is referred to as active transport.
