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.
Plan Ahead. Gather your bridesmaids and choose the desired dresses roughly six months before your wedding. Once you order the dresses, it can take as long as three months for them to arrive. When the shop receives the dresses, arrange a day for you and your bridesmaids to meet for the dress fittings. Accounting for the potential for delays and the necessity of second fittings, expect up to six weeks to have the garments altered. Each of your bridesmaids should have her dress ready about six weeks before the wedding.
