Which of the following best explains a method by which plants use long-distance signaling to carry out cell communication?

1. Gas hormones are released and travel through the air to reach their target cells.
2. Growth factors are released into extracellular fluid toward target cells via
paracrine signaling.
3. Molecules travel down a concentration gradient to target cells through
plasmodesmata.
4. Neurotransmitters carry chemical signals from dendrites to axons across
synapses.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.

The correct answer is b
