(4)
All living things are composed of one or more cells.
Cells are organisms’ basic unit of structure and function.
Cells come only from existing cells.
Cells contain the information necessary for regulating cell functions and
transmitting information to the next generation of cells.
24. The cell in the diagram is a prokaryotic cell because it does not have a nucleus and the DNA is found in the
cytoplasm.
OTHER
25. All cells have a cell membrane, organelles, cytoplasm and DNA.
