This article discusses the cell both as an individual unit and as a contributing part of a larger organism. Cells make tissues for organs. Atoms and molecules are atomic scale (sometimes called nanoscale or molecular scale) objects. What are molecules? (c) baking powder. WebBy far the largest portion of macromolecules are the proteins. Macroscopic-scale objects can be seen with the naked eye. Consider only the contents of the glass, not the glass or the container. WebEven though molecules, proteins, viruses, and cells are all tiny, there are significant size differences between them. Now that seems super small, so in some ways it's okay to categorize that into your super As long as all of the atoms are the same, the substance is an element. Direct link to s20161056's post how many kinds of cell is, Posted 5 years ago.
