Welcome Biologists! How often have you wondered how our skin heals when it's cut or how we can recover after an illness or how we develop from a baby to a teenager in a span of several years? Your questions will be answered soon enough as you embark on this scientific journey through the life of a cell! Many of the reasons why you can do all the things you do is because of an ity bitty structural and functional unit found in all living things - the cell. An adult human body is made up of about 60-90 trillion cells, each with a special purpose to help keep you alive. Yes ladies, you read that right....60 to 90 TRILLION cells! With that said, your task is to become a master biologist on a specific cell in the human body. Click on the TASK button to find out exactly how you will be doing this.
