12/6 Biology update and homework due 12/13

Hi folks,

Today we started our block on cell reproduction.  This will lead us directly into genetics and then evolution as we move forward.  Next week we will dive into mitosis and meiosis. 

For homework this week please do (and study) the following questions. Answers are included in an attached .pdf so that you can check and test yourself. The last thing you want to do is get one of these questions wrong and then study the wrong answer!

Remember, much of the following will be on next week's quiz.  However, any past quiz questions are fair game, so study all your old flash cards and quizzes.  It's been a while since we've seen those prefixes and suffixes so they are due to make a return visit as well. 

1.  What is a vesicle and what does it do?

2.  What does RNA polymerase do?

3.  What does DNA polymerase do?

4.  What is exocytosis?

5.  What is endocytosis?

6.  What is phagocytosis?

7.  What is pinocytosis?

8.  Would leaving the front do open so that flies can come in and out of the house at will be passive transport or active transport?

9.  Would kicking someone out of your house because he ate all the potato chips be active transport or passive transport?

10.  Is phagocytosis a from of endocytosis or exocytosis?

11.  What are the 3 steps of the cell life cycle (just interphase)?  

12.  What happens during each step?

13.  Why is the S step important?  In other words, what does it prepare the cell to do?

14.  What is the meaning of diploid?

15.  What is the meaning of haploid?

16.  Draw a picture and label the centromere and the sister chromatid.

17.  What is a chromatid?

18.  What is a chromosome?

19.  What is the difference between a chromatid and a chromosome?

20.  What is a somatic cell?  Are they diploid or haploid?

21.  What is a gamete cell?   Are they diploid or haploid?

22.   Which bio molecule is best for quick energy?

23.  What kind of molecule is a triglyceride and what does it do?

24.  In which bio molecule would you find nitrogen atoms?

25.  In which  2 bio molecules would you find a carboxyl?

26.  So in the cell we have transcription and translation and then the proteins wander into the rough E.R. or the Golgi body.  Now that they are all formed and trained, what do they do next?  In other words, what are their jobs?

27.  What does a lysosome do?

28. What's the difference between a vacuole and a vesicle?
