why is cell called the structural and functional unit of life?

Question

Answer

Cell is called the structural and functional unit of life because all organs ,tissues and organ system is made up of cell.

Answer

Because they r a point from which our life starts........and all living being r made up by cell......and very interesting thing is that with the help of cell tissue,organ,organ system and even an organism is formed.....

Answer

Cell is a basic unit of life

Answer

Cell is called structural and functional unit of life because body of all the organisms is made up of cell and it performs all the functions of our body.
it is also called basic unit of life.

Answer

Introduction: The Cell as the Structural and Functional Unit of Life

The cell is often referred to as the structural and functional unit of life because it is the basic building block of all living organisms. Cells carry out essential functions that are necessary for the survival and maintenance of life. They are responsible for various processes such as metabolism, growth, reproduction, and response to stimuli. This article will explain in detail why the cell is considered the fundamental unit of life.

The Structure of a Cell

Cells can vary in size, shape, and structure depending on the organism and its specialized functions. However, all cells share certain common features:

1. Cell membrane: Also known as the plasma membrane, it forms the outer boundary of the cell and controls the movement of substances in and out of the cell.

2. Cytoplasm: This gel-like substance fills the cell and contains various organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes.

3. Nucleus: The nucleus houses the genetic material of the cell in the form of DNA. It controls cell activities and coordinates cellular functions.

Functions of a Cell

Cells perform a wide range of functions that are vital for the survival of living organisms. Some key functions include:

1. Metabolism: Cells carry out metabolic processes, including the conversion of nutrients into energy, the synthesis of proteins, and the elimination of waste products.

2. Growth and development: Cells divide and differentiate to allow for growth and development of the organism.

3. Reproduction: Cells are responsible for the reproduction of organisms through processes such as cell division and sexual reproduction.

4. Response to stimuli: Cells can sense and respond to changes in their environment, allowing organisms to adapt and survive.

5. Homeostasis: Cells maintain a stable internal environment through various mechanisms, ensuring the proper functioning of the organism.

Importance of the Cell as the Unit of Life

The cell is considered the structural and functional unit of life due to the following reasons:

1. Independence: Cells are capable of carrying out all essential life processes independently. They can obtain nutrients, produce energy, and eliminate waste.

2. Reproduction: Cells can divide and reproduce, allowing organisms to grow, repair damaged tissues, and replace old or dying cells.

3. Specialization: Cells can differentiate and specialize to perform specific functions, such as muscle contraction, nerve transmission, or hormone production.

4. Evolutionary significance: All living organisms are composed of cells, and the diversity of life forms arises from variations in cell structure and function.

5. Disease and health: Understanding cellular processes is crucial for diagnosing and treating diseases. Many diseases result from abnormalities at the cellular level.

Conclusion

In conclusion, the cell is rightfully called the structural and functional unit of life due to its indispensable role in carrying out essential functions necessary for the survival and maintenance of living organisms. Cells are responsible for metabolism, growth, reproduction, and response to stimuli. By studying cells, scientists gain valuable insights into the complexities of life and the mechanisms underlying

Answer

All living organisms are made up of cell

Answer

∆every living object is made up of cell.
∆for eg: in humans cells of similarly type unit to perform tissues.
∆ Tissues together form organ system.
∆organ together form organ system and finally a whole body.
∆the specific cells perform specific type of function.
∆for eg: the muscles cell help to contractions and expansion and so on.
∆This means that cell give structure to a body.just like a house get it's structure by arrangement of tricks.
∆tge body gets it's structure by the cell.hence the cell is called the structural and functional unit of life.

Answer

This is because 1. It is the only smallest part in our body which performs all the functions by combining together 2 It is organized to form tissue than organs than organ system and at the last organ system is organized to form a whole life .

Answer

Living organism organisms such as all plants and animals are made up of specific types of cells. cells from tissues and this furthers from organs and systems. the basic structural unit is there for cell. cell is also the smallest entity in the body.each living cell performs different functions with the help of cell organelles located in them. basic bodily functions such as nutrition respiration osmoregulation X creation becomes functional unit of the body.
