Match the words of Column A with that of Column B.


Answer :

a) Phloem - ii) Translocation of food

Translocation of food means carrying the food from the location at which it is produced(source) to the location where it is needed(sink) I.e. from leaves to the other cells of plants.

Nephrons are the basic and functional units of kidneys that take part in blood filtration and removal of waste from it.
