WARM UP TASK 11/27 Read each statement on your “Intro to Cells video sheet” and put a T or F on the LEFT SIDE ONLY. (you are making your best guess)
AGENDA 11/27 • Ch 4 Notes #1 Intro to cells • Intro to cells video • Do you know your own cells? * Can get EC from this! *** MISSING TESTS – TAKE TOMORROW!!!!
LEARNING TARGETCHAPTER 4 #1 I can explain the major events in cell history.
Ch 4 NOTES #1 11/27 THE CELL intro
3.6 billion years ago – 1st cells PROKARYOTE - bacteria No nucleus
1.3 billion years ago EUKARYOTE CELLS – do have nucleus ; also organelles
Over time …. Cells became specialized – different cells do different things Brain cell Blood cell Skin cell…. and grouped together to become multicellular.
TAKE YOUR INTRO TO CELLS VIDEO SHEET OUT CELL VIDEO – while watching, write down if the statement is T or F. See how many you got right!
