Difference between tissue and organ

The main difference between tissue and organ is that tissue is the group of cells that perform a similar function, while the organ is the group of tissues that perform a similar function …

Tissue vs. Organ

There is a great diversity of life that exists on earth, but the cell is known as the basic structural and functional unit of life. All life forms are made up of the cell, but its complexities differ from one organism to another. That is why there are different types of species on earth. Some are unicellular while others are multicellular. Unicellular organisms are organisms that are made up of a single cell, for example protozoa, while multicellular organisms are organisms that are made up of a large number of cells. Such multicellular organisms require proper organization of the body’s cells to perform different jobs.So in multicellular organisms, the cells are properly organized at different specific levels. The cell, tissue, organ, and organ system are the level of organization in multicellular organisms. Some cells combine to make tissue; tissues combine to form an organ, different organs combine to form an organ system, and different organ systems combine to form a complete individual. So the tissue is the group of cells that perform the same function, while the organ is the group of tissues that work together. Connective tissue is an example of a tissue, while the stomach is an example of an organ.In this article, we will highlight the important differences between them. tissues combine to form an organ, different organs combine to form an organ system, and different organ systems combine to form a complete individual. So the tissue is the group of cells that perform the same function, while the organ is the group of tissues that work together. Connective tissue is an example of a tissue, while the stomach is an example of an organ.In this article, we will highlight the important differences between them. tissues combine to form an organ, different organs combine to form an organ system, and different organ systems combine to form a complete individual. So the tissue is the group of cells that perform the same function, while the organ is the group of tissues that work together. Connective tissue is an example of a tissue, while the stomach is an example of an organ.In this article, we will highlight the important differences between them.

The word “tissue” is derived from the French word “tissu”which means something that is woven. Tissue is a group of related cells that perform a specific function in the body. So tissue is a level of cellular organization that exists between a cell and an organ. The study of animal or human tissues is known as histology, while that of plant tissues is known as plant anatomy. Animals are made up of four types of tissues, that is, epithelial tissue, muscle tissue, connective tissue, and nervous tissue. Epithelial tissue is the type of tissue that lines the body’s cavities and surfaces and protects the body from mechanical damage and dehydration. Connective tissue connects and joins separate tissues and organs. Muscle tissue provides movement to the body and its different parts. Nervous tissue provides coordination to different parts of the body by transmitting nerve impulses in response to any external or internal stimulus. Plants are also made up of three types of tissues known as epidermis, soil tissues, and vascular tissues. The epidermis is the tissue that covers all parts of the plant’s body, such as leaves, stem and roots. Vascular tissues carry water, food, and nutrients, etc. throughout the body of the plant. Soil tissue is the tissue that plays an important role in photosynthesis and food storage. throughout the body of the plant. Soil tissue is the tissue that plays an important role in photosynthesis and food storage. throughout the body of the plant.

An organ is the part of an organism that performs a set of specific functions in the body and is made up of various types of tissues. Different types of organs are present in a multicellular organism and perform different specific functions. Some major organs in the body are the brain, lungs, liver, heart, and kidneys. The brain is part of the central nervous system and provides coordination in response to any external or internal stimulus. The lungs participate in the exchange of gases between the individual and their environment. The liver acts as a storage organ of the body and stores glycogen, etc. The heart is the organ that pumps blood to all parts of the body. The kidney is the body’s main excretory organ and plays an important role in removing waste products from the body. In plants, stem root and leaves, etc. are considered organs. The different organs of the body combine to form an organ system.

Key differences

1. A group of cells that performs a specific function in the body of an organism is known as a tissue, while a group of tissues that performs a specific function in the body of an organism is known as an organ.
2. The tissue is a uniformly distributed structure while the organ is a hollow structure.
3. Tissue is made up of similar cells, whereas an organ is made up of different types of tissues.
4. A tissue is a smaller level of organization, while an organ is a larger one.
5. A tissue requires less energy to perform its function, but an organ requires a greater amount of energy to do its job.
6. A tissue is a structural component of an organ, while an organ is a structural component of an organ system.
7. Tissue is capable of performing only one body function while an organ is capable of performing several body functions.
8. In the event of injury, the tissue can be repaired through fibrosis and regeneration, while the organ repairs itself by repairing its tissues.
9. Connective tissue and muscle tissue, etc. are examples of tissues, while the heart, liver, and kidneys, etc. are examples of organs.

From the above discussion, it is concluded that both the tissue and the organ are the organizational levels of a multicellular organism. While the tissue is a smaller level that is made up of similar cells and performs a specific function, the organ is a higher level that is made up of a group of tissues and performs different specific functions. Connective tissue is an example of a tissue, while the liver is an example of an organ.
