Much of this movement is to regulate the contents of the cell. This includes bringing material into the cell from the extracellular environment or the plasma membrane (endocytosis) or releasing material made within the the cell to the outside (exocytosis).
It really is an easy project...it just takes a little time. All and all, it took me about 6-8 total hours to make 4 bouquets, 10 bouts (my mom made those though) and about 15 centerpieces. I made two bouquets the day before our wedding and the other two the day of the wedding.
Asker's rating. 1  Between 8 and 6 weeks before the wedding you want to mail out the invitations. 2  8 weeks at the very latest. 3  The invites are mailed out 6-8 weeks before the wedding date. 4  I just sent out my invites for a April 25th date, with a reply of 50 days in advance (caterer needs at least 45 days).
