Difference Between Tissue and Cell

Tissue vs Cell
 

There are many differences between cells and tissues, and which are important to notice. Cells are the building blocks of tissues; tissues make systems, and finally all those together form an organism. There are different types of cell, as well as different types of tissues, but the basic properties of cells and tissues do not overlap with each other, to make it difficult to understand. Therefore, considering the difference between cells and tissues would be of much importance for anyone. This article intends to discuss those important differences between cells and tissues after following some basic characteristics about those.

Tissue

A tissue is an assemblage of cells of the same origin according to the definition. This assemblage mainly focuses in fulfilling one common function. It is important and should be noticed that the tissues are present only in the multicellular animals and plants only. The cells in a tissue may not be identical to each other, but the origin is the same for each one. There is always a substance known as the plasma between cells to keep it as a unit. There are four main types of tissues in animals known as Epithelial, Connective, Muscle, and Nervous. Those four types of tissues are present in all the multicellular animals in general, and the proportions of each type of tissue vary among species as well as individuals according to the genome. Therefore, it could be envisaged that different individuals of a particular species vary among themselves in the proportions of the different tissue types that each one has. That is one of the reasons for individual specialities of animals including humans, as well. Tissues account for all the activities performed by an organism, and all those basic types of tissues function as a whole unit through coordinating via hormonal and nervous signals. Generally, the nervous tissues coordinate a particular function, and muscle tissues execute it with the assistance of connective and epithelial tissues.

Cell

Cell is the basic functional unit of life according to the definition by many textbooks and scientists. A cell could be either the whole unit of an organism (unicellular organisms) or the very basic unit of a large multicellular animal or tree. However, all those big made multicellular organisms such as elephants or whales start their lives as a basic cell formed from a sperm cell and an ovum. However, a typical cell consists of few organelles such as mitochondria, Golgi bodies, lysosomes, ribosomes, nucleus, and some more. These minute organelles have different functions, and interestingly the proportions of the density of those organelles vary according to the basic function of a particular cell. Nucleus contains all the genetic information of the cell or animal and regulates all the activities inside a cell. Mitochondria is responsible for performing the metabolic activities. Additionally, the Golgi complex and lysosomes function in defending the cells. Each cell has a defined margin formed by the cell membrane, and the membrane is semipermeable. In addition, all the organelles are covered separately by membranes, which are similar to the cell membrane. Every function of the body is executed through cells and the importance of each cell of a particular animal or plant could never be underestimated. The importance could be clearly understood when a slight alteration of a particular cell results in a deadly cancer or an irreversible mutation.

 

What is the difference between Cell and Tissue?

• The density of particular organelles inside a cell differs among different types of cells whereas the presence of different types of cells differs among different tissue types.

• Tissues are found only among multicellular organisms, but obviously, not among unicellular animals.

• Cells are formed from organelles and cells form tissues. However, tissues form organs and systems.

• All the cells have a defined margin known as the cell membrane while not all the tissues have defined margins.
