Penicillin kills bacteria by interfering with the ability to synthesize cell wall. In this sequence, Escherichia coli were incubated in penicillin for 30 minutes. The bacteria lengthen, but cannot divide. Eventually the weak cell wall ruptures (last panel). You can view the bursting bacteria in a 610K time-lapse movie. To learn more about how penicillin works be sure to check out " What the Heck is Penicillin" at Jack's "Bugs in the News". penicillin killing E. coli
Plant cell models. Add wooden popsicle sticks w/ tape for cell wall, Ziploc bag (cellular membrane), Aloe vera gel (cytoplasm), bottle cap nucleus, plastic beads (ribosomes), small blue balloon partially inflated ? (vacuole), plastic fishing lure (mitochondria), green oval bean shaped bead (chloroplasts),.... What a fun visual!
