Transportation in plants in Education

Transportation is a crucial process in plants. Tress transport to get all the water and nutrients they need to survive from their roots to the tips of the leaves. The biggest constraint in the transportation of plants is water when. It ends up being the factor that is limiting the growth of the plants. Therefore, to overcome this problem, trees and other plants have their system for the absorption and translocation of water. The plant contains a network of conduits containing xylem and phloem. It is more like a circulatory system where blood is transported throughout the human body. Similarly, the xylem and phloem tissues are extended throughout the plant, which supplies water. These tissues originate from roots and move to the trunks of the trees. Alter, they branch off into the branches, further branching into every leaf like spider webs.

Transportation of plants commonly occurs on three levels-

·   Transportation of substance from one cell to another

·   Release and uptake of water and solute by the individual cells

·   The long-distance transport of sap between the xylem and the phloem.

Additionally, the transportation in plants has different means, i.e.-

·   Diffusion- It involves the passive movement of a substance from one cell to another or from one plant par to the cell.

·   Facilitated Diffusion- The gradient is crucial for diffusion. Therefore, a smaller substance is diffused fast compared to larger ones. Facilitated diffusion comprises antiport, symport, and uniport.

·   Active Transport- It pumps molecules against the concentration gradient.
