Tag: cell-the basic unit of life

The organism made up of many cells are known as multicellular.

• Cells are called the smallest structural and functional unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. 

• Organisms can consist of one cell to many cells. 
• The cell is the structural unit of life. Unicellular organisms are made up of one cell that performs all the functions.
•  Whereas, a multicellular organism that consists of multiple cells and a different group of cells perform different functions which give complexity to the multicellular organisms.

• The cells are the basic structural, functional and biological unit of all known living organisms. 
• Cells are the smallest unit of life that can replicate independently and are often called the building blocks of life. 
• The human body is composed of trillions of cells. 
• They provide structure for the body, take in nutrients from food, convert those nutrients into energy and carry out specialized functions. 
• Cells also contain the body's hereditary material and can make copies of them.

• The first characteristic of a living thing is that they are made up of cells. A cell is a basic building block of all organisms. 
• It is the smallest unit of organization in a biosphere. A cell performs the life process to maintains the survival of an organism.

Cells can be prokaryotic or eukaryotic. If the cells have dispersed nucleus i.e., nucleoid then these are called as prokaryotic cells. Eukaryotes are organisms, whose cells are organized into complex structures by internal membranes and a cytoskeleton.
So, the correct answer is option C.

• Cells are called the structural and functional unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. Cells provide specific conditions, for the occurrence of the metabolic reactions. These have specialized enzymes, which catalyze the biochemical reaction and regulates the functions of the body.

• Tissues are the group of cells, which may be similar or dissimilar in structures, but coordinates to perform specialized functions e.g., xylem.

The first man to witness a live cell under a microscope was Antonie van Leeuwenhoek, who described the algae, Spirogyra, in 1674. He named that cell as animalcules. He is also known as father of microbiology, as he was first to study the microorganism.
So, the correct answer is option D.

• The cell is considered to be the basic unit of life in many pathological processes. 
• In addition, the phenomenon of energy flow occurs in cells in processes that are part of the function known as metabolism. 
• Cells contain hereditary information (DNA), which is passed from cell to cell during cell division and from one generation to next. Thus, the correct answer is option D
