Chloroplasts
Chloroplasts capture the energy in sunlight and use it to synthesize energy-rich carbohydrates. This food made by chloroplasts provides the chemical energy needed by all forms of life. Mitochondria help cells to extract the energy in food molecules efficiently to power cellular activities.
A nerve cell is a cell that travels in a nerve bacilcly it is neuron and it transmits signals to the brain to do something so if we want the wave our hand the nerve cell/neuron transmits signals to the brain.
They can both be used to identify organisms. Also, the phenotype of an organism is different depending on the genotype of the organism, making them relate to one another.
Hope this helps. Good luck! :)
