week 10- Cell Biology sites--

I found the Intro to Cell and Virus Structure site to be very useful-- I loved the relative sizes and detection devices diagram. Interesting data point: human body has 75 trillion cells!

I took a lot of notes about these sites on my assignment sheet. Too tired to copy them all down now, but I swear I looked at them all!  Another interesting factoid-- "modern biology" is only since 1839 -- the idea that all living things are made of cells concept......

Also interesting-- questions about cellular evolution-- cells came from non-living chemicals--volcanic eruptions plus lightening plus UV radiation = amino acids rain down and form CELLULAR SOUP!  Or.... up from hydrothermal vents, or fell from meteors....... hmmmmmm?

Spikes Gallery-- I want to have a blown up picture of the fossil diatoms from Oamaru in my living room!   Absolutely magnificent.
