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 ofendoplasmic reticulum and ribosomes.

What do these structures reveal about its function?

Virus (Electron micrograph) – Note the lack oforganelles. Why do viruses need to infect a host cell toreproduce?

Tissues Dense regular connective tissue

You can determine function from the types and placement of thefibers. Look at the two slides.

Slide 1 – Dense regular unilateral fibers

Slide 2 – Dense regular fibers swirl in more than onedirection.

Which do you think undergoes forces in many directions?

Which supports forces in predominantly one direction?

Tissue Type	Draw the tissue which represents the relevant structuralfeatures. Be sure to include total magnification!	Describe the structure or form of this tissue	Location in Animal Body (possibly indicated on the slide)?
Simple Squamous
Simple Cuboidal
Simple Columnar

Through an investigation of the physical characteristics of eachfish, what can you conclude about the fish’s habitat orlifestyle?
