Answers
Answer:Our bodies are made up of about a hundred million million (100,000,000,000,000) tiny cells. You can only see them under a microscope.
Cells group themselves together to make up the tissues and organs of our bodies. They are a bit like building blocks. The diagram below shows what cells look like when they are grouped together.
Explanation:
Body tissues grow by increasing the number of cells that make them up. Cells in many tissues in the body divide and grow very quickly between conception and adulthood.
When we are grown ups, many cells mature and become specialised for their particular job in the body. So they don't make copies of themselves (reproduce) so often. But some cells, such as skin cells or blood cells are dividing al the time.
When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on. The diagram below shows cells dividing.
