Introduction to the Eukaryotic Cell
Exercise 9
+Announcements
Students have time to observe Week 8 plates and finish their LNAs.
Post Lab 9/Pre Lab 10 are due by the time your lab meets next.
LNA Eukaryotic Cell is due next week in lab.
+Goals
To learn the basic structures associated with eukaryotic cells.
To identify the differences between animal and plant cells.
To understand the basis of cell culture, and the changes imposed on cells under culture conditions.
To understand the techniques of fluorescence and electron microscopy and cell culture.
+Animal Cell
+Plant Cell
+The Exercise Part I: Plant cells: Onion epidermis
Basic cell structure of a plant lacking chloroplasts Iodine: observe nucleolus Janus Green: observe mitochondria
+
Part II: Animal cells: Human squamous epithelium Observe differences from the plant cells Do the mitochondria vary in size from those found in
plant cells?
The Exercise
+
Part III: Autofluorescence View Tradescantia under the fluorescent microscope Chlorophyll pigments autofluoresce
The Exercise
+
Part IV: Anacharis Leaf Cells View a living plant cell with chloroplasts
The Exercise
+
Part V: Electron Micrographs and Cellular Infrastructure View EM transparencies Identify organelles You may want to take notes for future identification (i.e. Exam 2 and
Final)
