Cells Alive Page 1 of4 Nome Alive- fnternet Cells Lesson URL: www.cel lsol ive.com-*-' Objective: You will look ot computer models of cells,leorn the functions qnd the descriptions of the cells and their components. Novigoting the site: Cells.alive hos o novigotion bor ot theleft. After occessing the poge, click on CELL \TOLOGY on the leftside novigotion bor. From here, you will occess the links: "How Big is o..", the onimol cell model, the plont cell model, and the bqcteriol cell model. Port A. "HOW 816 I5 A. .. ." Here you will look ot objects found on the head of o pin. Your job is to rank them in order of size on the chort below ond estimote the length of eoch (in nonometers, micrometers, or millimeters). The line in the bottom right corner of lhe screen is used to help you estimote. Sketch each of the objects. Object Sketch Size in nanometers, micrometers or millilmeters Human hair Dust Mite Red Blood Cells E. coli Staphylococcus Ebola virus Rhinovirus Port B: Bocteriol Cell Model - (you will need to return to the "Cell Biology" link to occess this poge, or hit your bock button) http /iwww.biolo gycorner. com/worksheets/cel1salive. html : U612009 Page 2 of 4 Cells Alive {. tliilt{.,iri,fiiri#"i:':%,, €ffir .,. .1q:li1*?i!tliii; .f :tIitri,, , . ::11ill:lrlirlrlh" , ,.,,,! t' 't lrt,llflJtir' ;1i':11t,i .
