Cells and tissues form a vital part of living entities. There are no tissues without cells and cells are responsible for making up the different types of tissues in all multicellular organisms. A cell is mainly found in every living organism.
Here are some basic differences between the cell and the tissue.
Cell and Tissue – Differences
|Cells are the smallest structural and functional units of an organism, which are characteristically microscopic.||Tissues are clusters of cells, specialized cells.|
|Found in both unicellular and multicellular organisms.||Found only in multicellular organisms.|
|Comprise of different cellular organelles, including the nucleus, mitochondria, lysosomes, Golgi apparatus, etc.||Comprise of similar types of cells, specialized for a unique function.|
|Two types of cells – Eukaryotic cells and prokaryotic cells.||Four main types of tissue- Epithelial tissue, Connective tissue, Muscular tissue, and Nervous tissue.|
|Functions include Growth, metabolism, and reproduction.||Has its own unique function. A group of similar cells combines together to perform a similar function. Example – Nerve cells of the nervous system are involved in different functions of the nervous system.|

A cell is the smallest structural and functional unit of life. Therefore it is referred to as a fundamental unit of life. Every function of the body is executed through these minute cells.
The term cell was first coined in the year 1665 by an English scientist Robert Hooke. Among all the living organisms, some organisms are unicellular, consisting of only one cell, which is capable of performing all the life functions. These unicellular organisms include amoeba, bacteria, Protista (majorly unicellular, few protists are multicellular) etc. Multicellular organisms consist of different types of cells which have specialized functions. Plants, animals, human beings, and birds are examples of multicellular organisms.
There are two different types of cells, the prokaryotic cells and the eukaryotic cells and these differences are mainly based on the presence and absence of the nucleus in their cell.
Tissues are groups of similar cells, working together to perform a specific function. The word tissue is mainly derived from “tissue” – a French word which is the past participle of the tisser (verb), “to weave”.
In the plant kingdom, tissues are divided into two different types: Meristematic tissue and Permanent tissue.
In the animal kingdom, tissues are divided into four different types:
- Connective Tissue: Blood, bone, cartilage, adipose, and lymph are examples of Connective Tissue.
- Muscle Tissue: Skeletal muscle, Cardiac muscle, and Smooth muscle are examples of Muscle Tissue.
- Nervous Tissue: Nervous tissue is seen in the brain, spinal cord, and nerves
- Epithelial Tissue: The surface of the skin, the reproductive tract, the airways, and the inner lining of the digestive tract are examples of Epithelial Tissue.
