Please find below the solution to the asked query  
          
1. Lymph is called as the modified tissue fluid because it is a yellow coloured viscous fluid which is formed from the tissue fluid or the interstitial fluid which is present in the interstices of the body tissues. This fluid then circulates in the lymphatic system of the body with the help of lymph vessels. It also covers the cells of the tissues and plays a very important role in the exchange of the wastes, nutrients and gases between tissues and blood.


3.  Lymph helps in defence by killing bacteria and other pathogens with the help of lymphocytes.It also helps in carrying digested and absorbed fats from intestine.
 
4.  Role of transpiration in plants is as follows:
  • Creates transpirational pull for transport
  • Supplies water for photosynthesis
  • Transports minerals from soil to all parts of a plant
  • Cools the surface of the leaves (due to the evaporation of water)
  • Keeps the cells turgid; hence, maintains their shape

Q 1 ans) Lymph is also called tissue fluid because after being separated from the blood cells, it gets collected in the tissues and whenever there is low blood pressure ,it comes back into the blood from the tissues.Thus getting the name of tissue fluid.
