Organelles Wrap up

First, If you didn’t yesterday, I asked you to turn in:

Cell diversity lab (only 4 need completed – everyone needs #6- Bacteria and #7(plant leaf))

SAS questions

Vocabulary Review

 ***This will be the last grade of this nine weeks***

Then to our DQ's

Daily Questions – Thursday October 25^th

Studies of fat cells and thyroid cells show that fat cells have fewer mitochondria than thyroid cells. A biologist would most likely infer that fat tissue….

a. does not require energy

b. Has energy requirements equal to thyroid tissue

c. requires less energy than thyroid tissue.  This question did not require you to know anything about the thyroid or fat cells, but simply what the function of the mitochondria is.  Remember, mitochondria convert organic compounds into usable energy for the cell.  That "Usable" energy comes in the form of ATP

d. requires more energy than thyroid tissue.

After germination, continued plant growth pushes first the shoot and then the leaves through the soil.  We would expect the emergent leaf cells to contain many Chloroplast for photosynthesis.  Because the developing stem must support the plant, we would expect those cells to develop Thick Cell Walls

Again - this question did not require you to know about plant germination and growth, it simply was seeing if you knew some features that were found in plant cells and how their structre relates with the function.

After this we went through the "organelles worksheet." I then showed you the animation from the university of Utah's "Learn Genetics" site on cell size and scale.  This is a great way to put into perspective the things we have been talking about.  Check it out here at http://learn.genetics.utah.edu/content/begin/cells/scale/

Here is another way to look at it!  Check out this video on Youtube to put the microscopic world into perspective!!

Again - just as a reminder - Make sure you check edline to see how you are doing, get the extra credit option and see if there is a Daily Question quiz you would like dropped!  It's hard to believe but we are 1/4 of the way done guys!!!
