Photosynthesis is the formation of organic material or food from combination of carbon dioxide and water while respiration is the breakdown of food to energy.

Neurons are the building blocks of the nervous system. They are the links so that information could be processed as electrochemical signals. There are three fundamental kinds of neurons in our body:
1. Motor neurons - they carry signals from the central nervous system (CNS) to the body parts such as muscle movement
2. Sensory neurons - they carry signals from other body parts to the CNS
3. Interneurons - interlinking neurons between the brain and the spinal cord
Thus, the correct and complete statement above should be
<span><em>Motor (efferent) neurons carry information </em><em>from </em><em>the brain whereas sensory (afferent) neurons carry information</em><em> to</em><em> the brain.</em></span>
Continuous conduction takes place in unmyelinated axon.
Explanation:
Based on the presence and absence of myelin sheath, the neurons had been classified as myelinated and non-myelinated neurons respectively.
In myelinated neurons the transmission of impulse takes place only at the non myelinated region called nodes of Ranvier. Due to this, the conduction in Myelinated neuron is saltatory.
The conduction in non-myelinated neuron takes place throughout the length of axon and it is continuous.
Saltatory conduction is faster than continuous conduction.
