Transpiration Diagram Xylem. Direction of travel in xylem. The cohesion tension model works like this.
In this lesson we will look at how this happens in vascular plants including the importance of xylem cohesion and transpiration in the process. Remember that in the monocot the xylem is found throughout the stem while in the dicot the xylem is found in rings like those you see in a tree trunk. During transpiration plants move water from the roots to their leaves for photosynthesis in xylem vessels.
The cohesion tension model works like this.
Plants perform a similar function of transporting these nutrients what we know as sap by using complex tissues called xylem and phloem. Water lost via transpiration at leaves must be replaced water molecules attracted to each other via cohesion caused by h bonds force strong enough to hold molecules together in a water column as water is lost via stomata water chain is pulled up transpiration stream. What is a xylem vessel. Transpiration evaporation occurs because stomata are open to allow gas exchange for photosynthesis.
