Hi folks,
Today we got into cells and cell structure.
For homework this week please read chapter 4 (pg 68) and answer the following questions based on the reading and on your notes. (I've included the answers below for you to check yourself.)
I would also recommend watching the video we saw in class today again. It's a fantastic overview of everything we discussed today.
WARNING! WARNING! WARNING! THERE WILL BE A QUIZ NEXT WEEK and it will be based strongly on these questions. Be sure to memorize ALL of these answers. I would recommend doing the homework, studying the homework and then printing off a blank version of these questions to take as a practice quiz. If you can get all of these questions right without looking at your notes your grade will thank you.
