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 often called the âbuilding blocks of lifeâ. They are the basic unit of living organisms. Anything that is living is made of cells. This means you are made of cells, trees are made of cells, an ant is made of cells, and an apple is made of cells. Can you name other things that are made of cells? Long ago, people did not know that cells even existed. Cells are so tiny, we cannot see them with our naked eyes. The invention of the microscope gave people to see and discover cells for the very first time. The first recorded discovery of cells was in 1655, when an English scientist named Robert Hooke took Anton van Leeuwenhoek's light. microscope and improved upon its design and studied a slice of cork under the lens.
