Cells and Viruses
Observe and draw the following cells.
Plant cell (slide) – Note cell wall,
chloroplast
What does this tell you about the functions of this cell?
Pancreatic cell (slide) – Note large amounts of
endoplasmic reticulum and ribosomes.
What do these structures reveal about its function?
Virus (Electron micrograph) – Note the lack of
organelles. Why do viruses need to infect a host cell to
reproduce?

Summarize your...
Multicellular organisms have a complex organization of cells
into tissues. Discuss the roles of cell-cell adhesion and
cell communication in forming these structures. Be sure to
address these processes in molecular detail.
Using what you know about stem cells and cell differentiation,
explain HOW bone marrow cells can travel to the brain and
differentiate into neurons. Make sure to discuss the role of cell
signaling processes and cellular induction.
Explain the composition of the bacterial cell envelope including
plasma membrane (Gram-&+), cell wall (Gram-&+) and outer
membrane (only Gram-) as well as their individual components.
Compare Gram+ and Gram- with regards to differences &
similarities.
