Transportation In Plants
All the students should understand the important biology topic transportation in plants. Transportation in plants is very important, it is regulated by various mechanisms. Plants carry all the nutrients and water they need to survive, from the roots to the tips of the leaves. To overcome this problem, trees and other plants have perfect systems for absorbing and circulating water. Plants contain a large network of ducts made up of xylem and phloem. It is like the circulatory system that carries blood throughout the human body. Similar to the circulatory system in humans, the xylem and phloem tissues extend throughout the plant. These conductive tissues originate from the roots and travel up the stems. Later, they divide into branches, and then branch more into leaf interstitials, like spider webs. In the case of active absorption, water moves through the distribution system and is absorbed according to the changes of the diffusion pressure deficit. It includes osmotic force and non-osmotic force. Humidity and temperature can have an impact. The force of water attraction is mainly generated in the root cells themselves. The rate of water absorption will be reduced if metabolic inhibitors are used. It occurs in fast transpiration plants. Plant movement is through the apoplast and it is absorbed by the attraction of perspiration and is produced by the tension created in the sap of the xylem. The rate of absorption is significantly dependent on the rate of perspiration. The force of water attraction is mainly generated in the cells of the dermis. Hope that all the students have understood transportation in plants properly.
