<span>Basically, the body needs to know what it is defending against. Your body can still (usually) fight off infection, even without an immunization, but it takes longer. Basically, your body creates cells with a receptor for a specific disease. When this cell finds the disease it is programmed for, it will send out signals to the "killer" cells to come and kill it. If your body doesn't have the "seeker" cells, it can't fight off the infection until it does. The opposite end are autoimmune diseases, where your immune system starts attacking itself.

The Euglena was green because it had chloroplasts in it, just like plants. The body structure at the base of the tail that relates to this is the photo receptor. These two enabled it to photosynthesize food like plants, but it could also take food from its surroundings like animals.
