Pre-activity Assignment and Assessment Activity: “Cell Engineers and Cell Detectives” Post-activity Assessment –Assessment Ask “detectives” to guess the function of the mystery cell, and explain why. Ask “engineers” to respond. Encourage discussions and clear up any misconceptions –Mini lecture Mesophyll cells (photosynthesis) vs. storage cells –Both have (different types of) plastids Goblet cells vs. neuronal cells –Both have extensive ER/Golgi (one for secretion, one for making membrane) –Clicker activities Guess the functions of a series of cell types with specific organelle contents and structural features Conclusions and Perspectives –Linking micro (organelles and cell function) and marco (organism level) –Inspire students to think about bigger questions How are cells different (differentiation) How does one cell (zygote) make different cell types following a spatial and temporal program (development) How have all these cell types come into being (evolution)
What does a photosynthetic plant cell look like? –Individual cells: high chloroplast content and other features –Working together: difference between two major types of mesophyll cells http://www.uri.edu/cels/bio/plant_an atomy/images/01.gif https://faculty.unlv.edu/schulte/Anatomy/Leaves/PrivetLeaf.jpg
Avocado Potato What do these cells do? –They also contain numerous plastids Same type of organelle as chloroplasts –What do they do? http://www.emc.maricopa.edu/faculty/farabee/biobk/amyloplast.jpghttp://nickrentlab.siu.edu/PLB400/Peterson_Images/ Persea_Lipid.jpg
What does a goblet cell look like? –High abundance of ER and Golgi –A trans Golgi apparatus cisterna is converted to mucinogen granules every 3 to 4 minutes during active secretion http://www.baileybio.com/plogger/images/anatomy___physiology/12. _powerpoint_-_digestive_system/goblet_cell.jpg http://www.bio.davidson.edu/people/kabernd/BerndCV/Lab/Ep ithelialInfoWeb/goblet cells.jpg
