We all reside in a world where non-living things coexist. And, since we are human beings and have the power to speak and understand and make others understand, we always ask ourselves - "what makes a living organism, living? The answer to all such questions is the presence of the basic unit of life in living organisms, i.e. the Cells. All types of living organisms are made from cells, which is present inside their body. Some living creatures consist of just a single cell who are termed unicellular organisms.
While others who are made up of many cells are known as multicellular organisms. So, the "Cells - The Unit of Life" chapter in NCERT Solutions for class 11 Biology is everything about Cells. The sub-topics covered under Cells are as follows:
A cell is defined as the functional and structural unit of a living organism, and this chapter discusses every detail about cells, like the meaning & types of cells, composition of cells, functions of cells, etc. Earlier, we have learned that entities possessing a single cell are called unicellular entities, and those composed of multiple cells are termed multicellular organisms.

A cell comprises various components, a few of which are absent in plants, while few are missing in animal cells.
