Amoebas also known as are single celled that means they can be smaller than a hair on your head. However so amoebas can get to be as big as your thumb. Amoebas grow when they have bigger food source, and take in more energy. Amoebas also have to reproduce, but amoebas reproduce differently than humans. The life of an amoeba is different than ours, so they have different ideal places and body structures. Amoebas usually stay out of our lives but when they come into our lives, some bad things can happen.

How Amoebas Reproduce and Take in Energy

Amoebas reproduction is different than humans. Amoeba’s reproduce asexual this means they duplicate themselves. First start by duplicate the nucleus, “Membrane bound organelle which houses most of the cell’s genetic information and controls the actions of the amoeba.”
(“Structure and Functions”). Therefore the nucleus duplicates first to help duplicate the other organelles. Then they other organelles randomly duplicate. After all the organelles duplicate the second set of organelles move away and form another amoeba. Reproduction is important but they need energy to do this.

Amoeba’s way to take in energy is totally different than humans. Amoeba’s take in energy by many steps. First the is for the amoeba to surround the food particle. Next is for the amoeba to form a vacuole around the food particle. Third is that the lysosomes comes to the vacuole. Finally the lysosomes help the vacuole digest the food particles. This helps the amoeba take in the energy needed to survive. That’s the amoebas way of eating. However you should understand the life and body of the amoeba.

Amoeba's Preferred Habitat and How Amoebas Adapted

The life in the body of an amoeba is way different than a life of a human. Their body’s definitely affects their way of life.Amoebas are part of the food chain in ponds. Amoebas preferred habitat is warm water and, dim light. Amoebas actually don’t have any shape. The amoeba has highly elastic cell membrane, a cell membrane is the outside layer of most cells. The amoeba’s flexible body helps the amoeba surround its food. “This is a very thin membrane, with good regenerative abilities and elasticity.” (“Structure and Functions”) The elasticity of the membrane helps the amebas everyday life. Eating is important for the amoeba, but what happens when they find a food sources in us is crazy.

How Amoebas Affect Us

Amoebas usually stay out of the life of humans, But when they get in the way of humans some horrible things can happen. In most cases amoebas have had caused death to humans. Every year about two people get infected and die from amoebas. Amoebas harm humans by eating the host's brain. The amoeba enters the human body because the amoeba is attracted to a chemical your nerve cells use to communicate. The amoeba enters through the nose and make their way to the brain. After they make it to the brain they use it as a food source. The amoeba has normal flu like symptoms.“After symptoms start, the disease progresses rapidly and usually causes death within about five days”.(Brain-Eating Amoeba).
.You would think we would be able to tell if you had an amoeba in your brain but doctors can’t tell till it is either too late.

“The average size of A. proteus is 500-1000 µm – visible to the naked eye!” (“Structure and Functions”). Amoebas can grow larger but need our brain as a food source hurting our lives. Also amoebas reproduction is much different that ours and a little more complicated. The amoebas way of life is adapted due to their cell shape. Those few survivors of the brain eating amoeba have shared their story.
