Question

What is a cell? plz have an explanation

Answer 1

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialised functions. Cells have many parts, each with a different function.

A cell is a membrane-bound structure that occurs as a functional independent unit of life (such as in unicellular organisms, e.g. bacteria, protozoa, etc.), or as the structural or fundamental unit in a biological tissue specialised to perform a particular function in multicellular organisms (e.g. plants and animals).
