Introduction

What are cells?

Cells are the structural, functional, fundamental and biological unit of life. These are a building block or smaller unit from which all organism is made up of. A sentence is made up of alphabets similarly life in the form of humans, animals and plants are made up of one or more than one cells.

It can provide support and structure, facilitates reproduction, help in transportation and energy production etc.

They are made up of proteins and organelles.
They collectively form tissue and ultimately forms a system.
The study of cell is also known as cell biology or cytology.

Who discovered cell and how?

Discovery of cells was the first step to modern technology and the field of science.

It was discovered by a biologist “Robert Hooke” in 1665. He observed a piece of bottle cork under a compound microscope and come up with small roomkind of figure that he eventually termed as “cells”. He saw the same thing which one can find in dry leaves. Thus, the discovery begins and it is being continued till now.

Types of cells:

As we studied, cells are the smallest unit. As per the organism and their organisation, cells are found in them which carry different and definite function.

Unicellular contains a single cell like the amoeba and multicellular contains many cells like animals.On this basis it is classified into two:
Prokaryotes – primitive celldoes not have a membrane bound nucleus. *Eukaryotes – developed cells have a membrane-boundnucleus.
