So what are the basic processes of life?

1. growing

2. responding to its environment

3. reproducing

4. getting food

Thesecells have the ability to change into other types of cells. Stem cells are at the center of a new field of science called regenerative medicine. Because stem cells can become bone, muscle, cartilage and other specialized types of cells, they have the potential to treat many diseases, including Parkinson's, Alzheimer's, diabetes and cancer. Eventually, they may also be used to regenerate organs, reducing the need for organ transplants and related surgeries.

Some cells need more energy, so they have more mitochondria. What kind of cell do you think would have more mitochondria in your body?

An animal cell may have zero or several vacuoles. Plant cells only have one big one, but it's busy holding water. On a plant cell, the vacuole may be the largest organelle.

Its job is to cushion the organelles. It's mostly made of water, but it feels like a gel.
