Estonia has been extremely successful in its re-integration with Europe. We joined the European Union in 2004, and slightly less than 7 years later (namely on 1 January 2011), we have adopted the common currency of the European Union â the euro.
When cells divide, they make new cells. A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process cell division and cell reproduction, because new cells are formed when old cells divide. The ability of cells to divide is unique for living organisms.n cell division, the cell that is dividing is called the parent cell. The parent cell divides into two daughter cells. The process then repeats in what is called the cell cycle. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins.
Cells are the building blocks of life. All living organisms are made up of cells. The cells were discovered by Robert Hooke in 1665. In the human body there are about 100 trillion to 1014 cells. hey are made up of a single cell. O rganisms like the amoeba, P aramecium are single-celled organisms, they are the oldest forms of life, they existed about 3.8 million years ago. Bacteria, a rchaea, protozoa, unicellular algae and un i cellular fungi are the main groups of unicellular organisms.
