What is the body made of?
   (metaphorically: love;)

What are cells? Cells are the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.  Plant cells are different than animal cells because unlike animal cells, plant cells are shaped like a quadralaterall instead of a round oval.  And, plant cells have larger vacuoles.

Differences between plant and animal cells.

Plant's have chloroplasts inside of their cells which help them produce food while the animal cell doesn't need these because they are consumers.  The nucleus acts as a brain for the cell, the mitochondria is like the engine of the cell.  The cell membrane filters what comes in and out of the cell.  Vacuoles are used to store nutrients for the cell.  The endoplasmic reticulum manufactures  and packages items for the cell.  Muscle cells in an organism help the body move by expanding and shrinking.  The nerve cells in an organism tell the muscle cells what to do and they tell the brain what the body feels, smells, hears, sees, and tastes.  Bone cells in an organism provide structure for the organism.  Muscle tissue in the heart makes the heart pump blood through out the body to provide nutrients to the body.  The respitory system in a human provides oxygen to the body and its organs including the heart which pumps blood through out the body.  The heart pumping blood is called the circulatory system which provides blood for the digestive system system which processes nutrients consumed by the body and eliminates left over waste.

Parameciums are single celled organisms that have some features that are the same as regular, multi cell organisms but they also have different parts like the cilia wjich is how the cell moves.
