Do all the cells of the body look like one another? Do they perform the same jobs?

Not all cells look the same because they are found in different parts of the body and they all do different things. Usually the ones that look the same will perform the same tasks but if a cell looks completely different then another then most likely the cells will not perform the same tasks. There are three main functions for cells, they are: reproduction, growth and repair. So they all have three things in common but other than that they can be mainly for building, repairing reproduction or defend against sickness (white cells only). They can also be different because a skin cell and a brain look different act differently reproduce at different times and just are for different purposes.
No not all cells look the same. This is because not all cells do the same job. There are three different jobs for cells and they are reproduction, repair and growth. Reproduction cells look different from repair cells because these cells do not do the same task. What makes cells look diferent aswell is the parts that the they have in them. reproduction cells may not have a part that a repair cell has, so that also factors into the whole appearence of cells.
No, not all cells in the body look the same. This is because they have different functions. Some cells reproduce and grow much quicker than others to fit there purposs in the human body. For example, some cells may be more permiable than others so they can take in more or less nutrients. Some cells are required to reproduce more qickly such as skin cells to repair a wound, compared to braincells which are harder to replace in the event of dammage. Although all cells grow, reproduce and repair, they all function at different rates. Because of there different tasks, not all cells in the body look alike.
