The students of 4th of ESO are doing a project related with cell’s division and cancer. This week in the lab they have discovered the different phases of mitosis. The aim of this experience is to observe and possibly photograph the process of cell multiplication called mitosis. In order to do this, they used onion root tips, where the growth is greatest and therefore the number of duplicating cells is relatively high. They enjoyed the experience because they could observe that those images that usually appear in books were actually happening under their miscroscopes.
