11-41. At least two things that all cells have in common? (use notes if necessary)?

REVIEW

11-51. Cells are the basic units of ___________ and ___________ in living things.

11-5Describe 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 don’t know, ask)

Go to shssci.wikispaces.com

Go to CP Bio

Go to CP Bio Unit 3After 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.

11-111. How are prokaryotic and eukaryotic cells different? as many ways as you can think of

11-11Describe 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 As prokaryotic cells evolved they

engulfed other prokaryotic cells, engulfed other prokaryotic cells, which eventually became eukaryotic which eventually became eukaryotic cellscells

– Scientists think that this is how Scientists think that this is how mitochondria and plastids became mitochondria and plastids became incorporated into plant and animal incorporated into plant and animal cellscells

– Evidence?Evidence?– Mitochondria and plastids have DNA Mitochondria and plastids have DNA

that varies from the rest of the cellthat varies from the rest of the cell Mitochondria have their own DNA and only Mitochondria have their own DNA and only

reproduce from division of preexisting reproduce from division of preexisting mitochondriamitochondria

Plastid DNA is very similar to DNA of some Plastid DNA is very similar to DNA of some photosynthetic bacteriaphotosynthetic bacteria

How to remember prok vs euk cells It’s 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
