The Cell Wall is a rigid multi-layered structure found in plant and bacterial cells, designed to hold the cells together and protect the cell from injury. They break down carbohydrates and sugars, making energy from the food we eat.
Lysosomes are the disposal and recycling units of the cell.
The Nucleus is the center of the cell. It is the control center for all cell functions. The Centrioles are nine sets of three fused microtubles arranged in an open star shape and located just outside of the nucleus. Look for them online in January.
