Cell Anatomy and Physiology

Microscopes allowed scientists to view organisms and their subunits.  This new advance in technology allowed us to better understand how organisms are organized on a small scale and see that all organisms at least have one cell.

The first microscopes were simple using one lens and natural light.


Scientists like Antonie van Leeuwenhoek used these simple microscopes to study the small world once unknown.






Robert Hooke used a compound light microscope to study cells and develop his cell theory.  These microscopes use a series of lenses to magnify the image to an even greater degree.  He coined the term "cells" because he thought that the compartments looked likes cells in a monastery.  










Current microscopes used electricity and provide even more detailed images for scientists to study.

We also discussed cell anatomy and function.  Below are diagrams and charts to help you study!

Tomorrow we look at our own cheek cells and possibly plant tissues.

Out until then,  Bode!

  1. Awesome blog. I enjoyed reading your articles. This is truly a great read for me. I have bookmarked it and I am looking forward to reading new articles. Keep up the good work! I also agree that Scientists like Antonie van Leeuwenhoek used these simple microscopes to study the small world once unknown. compound microscope
