IA Nucleus • cgraphy yetephan plane cambrane 100X 400X 2. At what magnification were you able to clearly observe the cell and its nucleus? 3. Using cell model and your textbook, label the following structures in the cell diagram: centrioles, chromatin, cytoplasm, Golgi complex, lysosome, mitochondrion, nuclear envelope, nucleolus, plasma membrane, ribosome, rough endoplasmic reticulum, smooth endoplasmic reticulum, nucleus. begin

Answer 1

QUESTIONS In this context, the word parfocal refers to those objectives that are able to no refocus when they are changed. For example, when we change the magnification to another, the lens wont lose their focus, the parfocal lens makes this possible. QUESTION 2 In most of the cases, the 400x allows you to observe a more detailed imagen of the nucleus Plasma membrane Ribosome Cytoplasm Smooth endoplasmic reticulum Rough endoplasmic reticulum Centrioles Golgi complex E G 4 Chromatin Chromatin Nuclear envelope Nucleolus Nucleus a envelope le h Lysosome Mitochondrion
