Cell is called the fundamental unit of life. A cell is capable of independent existence and can carry out all the functions which are necessary for a living being. A cell carries out nutrition, respiration, excretion, transportation and reproduction; the way an individual organism does. A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.

Sap is a fluid transported in xylem cells (vessel elements or tracheids) or phloem sieve tube elements of a plant. These cells transport water and nutrients throughout the plant. Xylem sap consists primarily of water, along with hormones, minerals, and nutrients. Phloem sap consists primarily of water, in addition to sugar, hormones, and mineral elements dissolved within it. Tree sap flows through sapwood, which produces carbon dioxide.
