Biology - March 2007

If you're growing fungi in a petri dish with agar, clearly it will grow up as well as out, so would it be possible to limit the space above the fungus, ie place a lid over it at a certain distance from the agar, so that it will just grow outwards, or will this affect the overall area result?

I would like to become a scientist and so i choose to go for biotechnology after I graduate from high school. But what I saw from websites on careers offered to biotechnology are so limited and kind of lame like glasswasher somemore! I thought in my mind that biotechnology studies and research new things, invent tools or weapons for society, but what it was was just not i imagine to be! Do they really has a name scientist on it too? Does biotechnology really have a bright future? Then in a way how? It saddens me when i read even more about biotechnology.. Heres the link.. http://www.accessexcellence.org/RC/CC/bio_intro.html to it..
