Cells Cells The basic unit of living organisms Reinforced through the Cell Theory Robert Hooke in the 1600s observed cork under a microscope and named the structures he saw cells Many scientists then studied cells. Their work is summarized in the cell theory: All organisms are made up of one or more cells The cell is the basic unit of structure and organization of organisms All cells come from preexisting cells

Validating Cell Theory Types of microscopes Compound light microscopes: use lenses to magnify objects up to 1500 times Total magnification of the object is therefore calculated by multiplying the magnification of the ocular (eyepiece) times the objective (located in the revolving nosepiece) Our Lab Microscope can magnify (40x, 100x, 400x, 1000x)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
