describe the Transportation system in plant
Answers
ÂnsWêR :
The system of moving substances in different parts of body is called transport system. In plants, food and water are transported by bundles of tubes present in stem called phloem and xylem. In animals, food, water and respiratory gases (oxygen and carbon dioxide) and other substances are transported by blood
ANSWER:−
In plants water is transported by the help of a tissue called Xylem in two ways:
1. Root Pressure .
2. Transpiration Pull.
Root Pressure :-
In this , water is transported by the Pressure of root. But this theory is only applicable to plants of certain height.
Transpiration Pull:-
In this , water is transported by transpiration force. Due to this a suction Pressure is created in the cells of leaves due to which they demand water from the neighbouring cells and ultimately from Xylem tissue.
