The Nervous system of the body consists of all the nerve cells. It is the body's "speedy" electrochemical communication system.
every neuron (nerve cell) has a long process known as 'axon' which is used to contact the next cell in the circuit. The receiving cell (another neuron) has small processes called 'dendrites' which are contacted by the axon. Now the neurons, like all other cells in the body, are enclosed by a selectively permeable cell membrane - which means it allows certain chemicals to pass through, while others are prevented from entering or leaving the cell

Answer: A and B
Explanation:
Monosynaptic reflex arc consists of only two neurons, one motor neuron and one sensory neuron. Monosynaptic means the presence of a single synapse of chemicals. Monosynaptic reflex Arc simple reflection that involves transferring input from the sensory neuron to the correct motor neuron through a single synapse in the spinal cord.
For example: the action of knee-je.rk reflex.
As the A refers to sensory neuron and B refers to motor neuron, sysnapse between A and B is a part of Monosynaptic reflex arc .
Chloroplast is an organelle, having chlorophyll pigments in them. These pigments trap light energy to support photosynthetic reaction. Chloroplast are specific to plant cell because plants are the autotrophs which can prepare their own food by conversion of light energy to chemical energy.
