Cells can be divided into two types, prokaryotic cells and eukaryotic cells, but it has also been suggested that they should be divided into three types, namely, the ancient nucleus cells that originally belonged to prokaryotic cells are independently separated as a class. The discipline of studying cells is called cell biology .
The cells are so tiny that they can be seen under a microscope , and they come in many shapes. It is mainly composed of the nucleus and cytoplasm, with a cell membrane on the surface. There are cell walls outside the cell membrane of higher plants, and there are often plastids in the cytoplasm, chloroplasts and vacuoles in the body , and mitochondria . Animal cells without cell walls, often cytoplasm central body , and higher plant cells.
- Cells have functions such as exercise, nutrition and reproduction.
