What part do all cells contain?

Answer 1

All cells have a plasma (cell) membrane, cytoplasm, and hereditary material. The plasma membrane controls what enters and leaves the cell. Cytoplasm is where most of the life processes occurs. The activities of the cell are controlled by the hereditary material. In small, simple cells called prokaryotes, this coded hereditary material floats free inside the cytoplasm. In larger, more complex cells called eukaryotes, the coded DNA is contained in a membrane bound structure called the nucleus. Eukaryotic cells have other cell part (organelles) that prokaryotes don't. So both prokayotes and eukaryotes have the three cell parts described above.
