Cellular Transportation, Mitosis & Meiosis
Webquest
Task 1:
Visit the website http://www.educypedia.be/education/biologycelldiffusion.htm
Pretend you want to design a website
about osmosis and diffusion involving cells.
You decide to visit some exiting websites for hints. Visit five of the
links from the website above about diffusion and osmosis. Read through their tutorials and look at
their animations. For each one, write
their explanation of diffusion and osmosis, make a simplified drawing of their
animation, and then indicate how accurate you believe their animation is and
how you would improve it.

Task 2:
Pretend that a philanthropist (person
who gives money to charitable causes) is thinking about giving money for cancer
research to a firm who claims cancer is caused by ghosts. Your job is to convince him that cancer is
caused by an error in cellular division.
Visit the following websites, outline the
process of cell division & mitosis, then write a SHORT letter to the
philanthropist explaining the link between cell division and cancer.

Task 3:
Start by reading the NOVA article “18
Ways to Make a Baby,” located at http://www.pbs.org/wgbh/nova/baby/18ways.html.
Pick any of the methods past 4 (that means 5 and up). Explain that process, outline
the process of meiosis, and then mention any problems that might arise between
the two processes. Meiosis animations
can be seen at:
