Cells and tissues are both structurally introduced in all organism and both have equal importance. There are no tissues without the cells and cell make-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 vs Tissue
|Cells are the smallest, structural and functional unit of an organism, which is characteristically microscopic.||Tissues are the distinct types of material consisting of specialized cells and their products.|
|Found in both unicellular and multicellular organisms.||Found only in multicellular organisms.|
|Are microscopic.||Are macroscopic.|
|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.|
|Developed from mitosis and meiosis cell divisions.||Repair through regeneration and fibrosis.|
Functions include Growth, metabolism, and reproduction.
|Has its own unique function. A group of similar cells combines together to perform a similar function and to form organs.|
The cell is the smallest structural and functional unit of life. There is no living creature existing on the planet earth without the cell. 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, algae, bacteria, fungi, protista etc. Multicellular organisms consist of different types of cells which have specialized functions. Plants, animals, human beings, 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. They are structurally and functionally similar to the cells. The word tissue is mainly derived from a Latin word meaning 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, tendon, adipose, and ligament are examples of Connective Tissue.
- Muscle Tissue: Skeletal muscle, Cardiac muscle, and Smooth muscle are examples of Muscle Tissue.
- Nervous Tissue: Brain, spinal cord, and the peripheral nervous system are examples of Nervous Tissue.
- Epithelial Tissue: Surface of the skin, the reproductive tract, the airways, and the inner lining of the digestive tract are examples of Epithelial Tissue.
