How can so many types of tissues in our body arise from a single cell?
In: Biology
So, real quick, tissue is just a bunch of cells working together to do a specific job. They are specialized cells.
Now, everyone here has started out as one cell. Eventually, over time, that one cell divided again and again and again. Until there is a bunch of cells. During that time, they decide, “you know what guys, this is gonna be a big organism, so to make sure everything runs smoothly, we are gonna have divide up to do different jobs. ” So they do, which is when the cells specialize in a job. Some cells focus on being heart cells, others work at being an brain, and so on and so forth.
Another bit of information that you might not be looking for is that each cell have DNA, and in that DNA they have the tools (genes) to perform every function for every type of specialized cell. But, cells can permanently turn off those tools so they don’t end up making the wrong proteins in the wrong place.
