What is the function of the Body Tube in a microscope?

Back

The Body Tube holds the eyepiece and the objective lenses at the correct distance from each other, allowing for proper magnification and focus.

Front

What distinguishes a Eukaryotic cell from a Prokaryotic cell?

Back

Eukaryotic cells contain a nucleus and membrane-bound organelles, while Prokaryotic cells do not have a nucleus and are generally simpler in structure.

Front

What is the role of the Golgi Apparatus in a cell?

Back

The Golgi Apparatus modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage or transport out of the cell.
