Cells - The Real Thing

A cell is the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic. (Resource: www.dictionary.com)

Every human being has about 100,000,000,000,000 cells in their body. There are actually more than one type of cell. There are blood cells (red,white,etc.), skin cells, and a cell for every part of your body. There are two types of cells. The plant cell or an animal cell. The plant cell is surrounded by a thick and rigid membrane; the animal cell can take forms, it is without a cell wall. Plants, as you probably know, need to make thier own food. That's why plants use chloroplast to transfer sunlight in to energy. Every living organism on earth has a cell. A cell has many jobs, including digesting, traveling, and reproducing. When old cells die, new one should form.
