Reflection on the topic CELL...

I learnt that cells are very important to organisms.
They are classified in many ways. For example, harmful and helpful.
Harmful cells are bacteria, cancer cells etc. Helpful cells are white-blood cells and red-blood cells. However sometimes, too many of good cells may cause in greater harm. Thus both types must be in balance and not too much or too little.

Also, I leart that even a cell microscopic thing can cause a great change in the organism and the factors in life. A organism cannot live well with a part of itself missing, thus telling me that in all things must be balanced in order to have a healthy and happy life...
