SUMMARY

The size order from smallest to largest is as follows: electron, atom, molecule, organelle, and cell. An electron is an elementary particle with a negative charge, while an atom is the smallest component of an element that retains its chemical properties. A molecule is defined as the simplest structural unit of an element or compound. Organelles are specialized parts of a cell, which is the basic structural and functional unit of all organisms. None of these components, except for cells, are visible under a compound light microscope.

PREREQUISITES
  • Understanding of basic biological concepts such as cells and organelles.
  • Familiarity with atomic structure, including electrons and atoms.
  • Knowledge of molecular composition and chemical properties.
  • Experience with microscopy techniques, particularly compound light microscopy.
NEXT STEPS
  • Research the structure and function of various organelles within eukaryotic cells.
  • Study atomic theory and the role of electrons in chemical bonding.
  • Explore the differences between prokaryotic and eukaryotic cells.
  • Learn about advanced microscopy techniques that can visualize smaller structures, such as electron microscopy.
USEFUL FOR

Students in biology or chemistry, educators teaching cellular biology, and researchers interested in microscopy and cellular structures will benefit from this discussion.

Homework Statement


4. atom, cell, electron, organelle, molecule. Define each of these terms and list them according to size from smallest to largest. Which of these, if any, are visible in the compound light microscopes we use in lab?

Homework Equations


The Attempt at a Solution


largest to smallest:
cell - the basic structural and functional unit of all organisms
organelle - a specialized part of a cell; analogous to an organ
molecule - the simplest structural unit of an element or compound
atom - the smallest component of an element having the chemical properties of the element
electron - an elementary particle with negative charge
is this right?

yup. Your definition of molecule and atom could be a little more precise/clear.
