      They perform so many functions, and they are the energy/battery stores for our body to allow them to do all the functions that we need in order to do all our day to day activities! Super complex and still so much for us to learn 👍

      There are 37.2 TRILLION cells in our bodies. Each of them is a part of a different family and that family has a function in helping us to stay alive and do the things we do everyday. They are what make us so if we didn’t have cells, we wouldn’t exist most likely. They allow us to get the energy we need to move, talk, breathe, they digest our food, protect us from viruses and bacteria, help us to repair ourselves and so on and so on.

      If you mean why do we need cells for research purposes, well there are many reasons. Studying cells in a dish allows you to ask research questions about how they work so we can understand our bodies more. Once we know more about how our bodies work normally, we can use that knowledge to try and come up with new medicines and treatments. You can use cells now to start testing drugs. Using cells also means that we don’t have to test on animals, although that is a necessary evil.

      I hope that answers your question?

      Because we are made of them! They each do different things and help you move, breathe and function!

      We are made of cells! They do lots of different things to keep us alive – help us to breathe, digest food, send messages between different parts of the body, attack viruses, avoid getting hit by buses…

      I believe during the evolution, life found that it did better when it was organised as a compartment with smaller compartments in it, each in charge of different cellular processes. As unicellular life evolved, it found it did even better when more of these cells worked together.

      Sorry if this is not what you meant by this question!

      We’re made of cells! Without them, we wouldn’t exist.
