Cell as the basic unit of life
Cells are the basic and smallest unit of life. A microscope is needed to see cells because they are so tiny. A microscope has lenses, clips, and a stage to hold samples, as well as focus knobs, to magnify cells and their structures, like the nucleus, cell membrane, and cytoplasm in cheek and onion cells. Different plant cells like onion cells have additional structures, such as a cell wall, chloroplasts, and vacuoles.
