Why animals do not have a cell wall?
Asked by | 10 Apr, 2008, 02:47: PM
Expert Answer
The lack of a rigid cell wall allowed animals to develop a greater diversity of cell types, tissues, and organs. Specialized cells that formed nerves and muscles—tissues impossible for plants to evolve—gave these organisms mobility.
