Phloem is actually composed of still-living cells that transport sap. Perhaps you are asking about xylem which is composed primarily of dead cells.
Cellulose
Muscles attach to the exoskeletons of invertebrates at sites called apodemes. Apodemes and the exoskeleton are primarily composed of a polymer called chitin.
