Answer:
A Cell (from Latin cella, meaning "Small Room") is the basic Structural, Functional, and Biological unit of all known Living Organisms. A cell is the Smallest Unit of life that can replicate independently, and cells are often called the "Building Blocks of Life".
Discovery of the cell
Hooke saw honeycomb-like structure when he observed thin slices of cork under a microscope. He noticed that each box was separated from the other by a partition or a wall. He was the one to name each of these boxes as cells.
Organisms Show Variety in Cell Number, Shape and Size
There are billions and trillions of cells in a tall tree or a large animal. A human body also has trillions of cells which have different shapes, sizes and functions.
Organisms can be of two types:
Multicellular Organisms are made up of more than one cell. For Example, Mango Tree and Frog.
Unicellular Organisms are made up of a single cell. For Example, Amoeba and Paramecium.
Amoeba, which is a single-celled organism, does not have a definite shape. Its shape keeps changing as it moves or feeds, protruding parts of its body to form 'pseudo' (meaning 'false') 'podia' (meaning 'feet'). These projects are known as pseudopodia.
Most cells are round, spherical or elongated. Some are spindle-shaped which are long and pointed at both ends. Nerve cells or neurons are quite long and are branched out to receive and transfer messages.
