At least two things that all cells have in common? (use notes if necessary)?

REVIEW

Cells are the basic units of ___________ and ___________ in living things.

11-5 Describe and interpret relationships between structure and function at various levels of biological organization. TODAY: What organelles can be found in a cell and what do they do?

Teach an organelle: Groups of two w/ one laptop Time to prepare = 20 minutes Task: Prepare one ppt slide including a student friendly def. + at least 1 picture. 1 student will present def to class + the other will explain the picture(s) (I will decide who does what so both of you should be ready to do either!). Presenting time = 45 seconds – 1 minute …PRACTICE

When Done: Save under dsto… (if you dont know, ask) Go to shssci.wikispaces.com Go to CP Bio Go to CP Bio Unit 3 After Posting: What do you want your classmates to write down? What exactly are you going to say about your picture? Practice NOT reading the slide. My.hrw.com Chapter 4 Username = dhe5n Password = p5e8n

power house of the cell = (organelle notes)?

11-10 Describe and interpret relationships between structure and function at various levels of biological organization. TODAY: What organelles can be found in a cell and what do they do?

How are prokaryotic and eukaryotic cells different? as many ways as you can think of

11-11 Describe and interpret relationships between structure and function at various levels of biological organization. TODAY: How are prokaryotes and eukaryotes different? adding to what we already know

REVIEW

Which do you think is older? Scientists think prokaryotic cells evolved first, since they are less complex

Endosymbiosis: Endosymbiosis: –As prokaryotic cells evolved they engulfed other prokaryotic cells, which eventually became eukaryotic cells –Scientists think that this is how mitochondria and plastids became incorporated into plant and animal cells –Evidence? –Mitochondria and plastids have DNA that varies from the rest of the cell Mitochondria have their own DNA and only reproduce from division of preexisting mitochondria Mitochondria have their own DNA and only reproduce from division of preexisting mitochondria Plastid DNA is very similar to DNA of some photosynthetic bacteria Plastid DNA is very similar to DNA of some photosynthetic bacteria

How to remember prok vs euk cells Its all in a hand bag: Girls…when going to a wedding / fancy occasion describe your purse – –Small, compact, just the stuff you NEED The rest of the time, what are most of your purses like? – –Big. Lots of room, extra stuff you may not need
