Introduction:
Every living thing reproduces, this means that has the ability to produce more living things. In this web quest you will learn and review the processes in which the cell is able to reproduce itself either for sexual or asexual types of reproduction.
The task:
In this Web Quest you will fin a list of questions that you need to answer correctly. For each question you will find an specific Internet address that you will have to visit to find out the proper information. Send your answer sheet (create a WORD document) to the address vanevet77@hotmail.com (send it to yourself also for backup)
Process:
Instructions: Answer the following questions by going to the specific Internet address below each of the questions.
Evaluation:
You will be graded as follows (rubric description):
Ø Followed instructions precisely: Student followed all directions given by the teacher at the beginning of the class. (20 points)
Ø Quality of writing: There is a thesis that summarizes upcoming content. Grabs the reader’s attention uses proper vocabulary terms for the science content, correct punctuation and grammar (20 points)
Ø The question is answered correctly and in a concise and clear matter (20 points)
Ø Usage of Internet addresses and info: uses the specific address that is published and if not cites the author or source (20 points)
Ø Completeness: The work is finished completely at the end of the 45 minute period class. If not, it will be graded according to how many questions are answered of the total (20 points)
TOTAL. 100 points

Conclusion:
By now you should now the Difference between the processes of mitosis and meiosis and how they are involved in the two types of cell’s reproduction (sexual and asexual. These processes also may go through mistakes caused by various factors, when there is a mistake in mitosis the result is cancer, and mistakes in meiosis are collectivly called nondisjunction.
