A medley of questions - diameter of flagella, age, and W7

Three questions that have persistently been gnawing at me that I am submitting
for the expertise of the Chlamydonas community:

1.  What is the approximate diameter of the flagella in C. reinhardtii?

2.  Is there an approximate age that C. reinhardtii cells live to?  Days, weeks?

3.  I have come across a number of different descriptions of the W7 cell wall
layer in C. reinhardtii.  Is it now better understood to have a specific
function or fate?  For example, is it transient and en-route to being secreted
into its environment, is there any evidence that it adsorbs or incorporates
compounds from its surroundings, does it serve a structural purpose?

I would be grateful for any enlightenment on these topics.  Many thanks in advance. 

Sincerely yours,
Doug Weibel
