Fascinating Facts About The Cell
A cell is the smallest, fundamental unit and building blocks of all living organisms. The term ‘cell’ is initially derived from the Latin word “cella” meaning a small room. The single and minute cell carries out numerous biological activities of a living organism. Therefore, the cell is called the structural and functional unit of all the living species existing on the planet earth.
Some organisms like bacteria are made up of a single cell, while other living species are made up of trillions of cells, including animals, birds, plants and human beings. As per the levels of the organization, a group of cells form tissues, tissues make up organs, and organs form an organ system.
Let us know some interesting facts about cells.
The first cell to originate on Earth was a Prokaryotic cell, and later evolved the Eukaryotic cells.
The size of a human cell varies between 10 µm and 100 µm. Furthermore, the size of a cell is generally determined by its surface area and not by the length.
There are two main types of cells – the Prokaryotic and the Eukaryotic cells and are classified based on the presence of cell organelles and the true nucleus.
The human body is composed of trillions of cells, which have their specialized functions. Every day billions of cells are created and more than 200 million cells die per minute.
Plants are the main source of food on the planet earth. Comparable to the animal cells, plants do have their specialized cells, which are involved in performing specific cell functions.
The average size of a human cell ranges from 10 µm and 100 µm. Furthermore, the size of a cell is generally determined by its surface area to volume ratio.
The feminine egg is the largest cell in the human body and the smallest is the male sperm cell.
The longest cell in the human body is the motor neuron which measures 1 meter in length and about 0.1 millimetres in diameter.
A cell contains a specialized subunit or cellular components, which are collectively called the Cell Organelles. All these cell organelles function together to keep the cell active and alive.
All the biochemical reactions in a cell, including the growth and development and cell expansion are carried out by the Cytoplasm. Apart from these, the centrioles function as the microtubule-organizing centre, which is involved in the arrangement of the cell organelles.
