Question

How many cells do humans have?

Answer 1

Hint: A cell is the basic unit of life. All living beings are made up of cells. The cells are capable of performing all the functions. Human beings are Eukaryotic multicellular organisms.

Complete answer:
The cells are the fundamental unit of life. The living beings are made up of several cells similar or dissimilar which all together perform a specific function. A cell is an autonomous body that can work on its own and perform all its metabolic activities by itself. For example, a unicellular prokaryotic cell-like cyanobacterium performs all its functions and metabolic activities including photosynthesis on its own.

In the case of multicellular organisms like humans, the group of similar cells forms tissues and the group of tissues forms organs and thus organisms. Humans’ cells are made up of approximately 100000 million cells that are similar and dissimilar in structure and function but work together to form a living being. And also Most recent estimates put the number of cells at around 30 trillion.

The cells have a capacity for dividing and redividing. The cells divide for growth development and repair of the body. As the age of an individual increase, the number of cells in the living being decreases. An infant has the maximum number of cells. The cells differentiate and ultimately lead to death.

Thus we can conclude that humans have approximately 100000 million cells.

Note: The cell is made of several membrane-bound and non-membranous organelles which perform various functions. These organelles are enclosed within a cell membrane and are dispersed in a fluid matrix called cytoplasm. Some organelles are mitochondria, Golgi apparatus, ribosomes, lysosomes etc.
