Question

Why are cells the basic unit of life?

Answer 1

A cell is a cytoplasmic mass that is outwardly attached by a cell membrane. Cells are the smallest structural units of living matter and make up all living things. They are usually tiny in size. Most cells have one or more nuclei, as well as additional organelles that perform various functions.

Complete answer:
The cell is the basic structural and functional unit of life.
The cell is the most basic building block of our bodies. Cells make up every organ in our body. To generate new organs and gametes, cells divide and multiply. Cells are also necessary for carrying out a variety of life-sustaining operations. Cells also offer shape and structure, as well as digest nutrients and transform them into usable energy.
Specialized cells fulfil distinct activities in multicellular organisms.
Example: RBC is a type of blood cell that is largely responsible for transferring oxygen and carbon dioxide. The photoreceptor cell in the eye is an example of a specialised cell. Light is converted into signals that can influence biological processes by this type of cell.
Because they come in discrete and easily recognised bundles, cells are considered the basic units of life. That's because all cells are surrounded by a structure called the cell membrane, which acts as a clear barrier between the cell's internal and exterior environments, much like the walls of a house.

Note:
A plasma membrane surrounds a cell, forming a selective barrier that permits nutrients to enter while preventing waste materials from leaving. The cell's interior is divided into several specialised compartments, or organelles, each with its own membrane.
