Nerve cells are specialized to transmit chemical signals throughout the body. Some nerve cells in humans can be several feet long. Nerve cells transmit signals by allowing chemicals to enter and exit the cell very quickly. Which organelle helps the most with this process?
A
the chloroplasts because they provide the energy needed to allow chemicals in and out of the cell
B
the cell membrane because it acts as a filter to allow nutrients and chemicals in and out of the cell
C
the cell wall because it provides support and structure for the cell as chemicals are moving in and out
D
the nucleus because the genetic material contains the plans for how the chemicals enter and exit the cell
