Answer:
Sensory neurons
Explanation:
On the basis of direction of conduction of nerve impulse, neurons are classified as sensory neurons, motor neurons, and interneurons. Sensory neurons are the afferent neurons and serve to carry the sensory information from sense organs to the central nervous system. These neurons have sensory receptors at densities to sense the stimulus or are associated with individual sensory receptors. As the stimulus is sensed by the receptor, the sensory neuron fire the action potential which is conveyed to the central nervous system.
Answer:
B. Chloroplasts have flagella and cilia and these structures are similar in shape and function to flagella and cilia found in bacteria.
Explanation:
The ENDOSYMBIOTIC THEORY is a theory that suggests the evolution of eukaryotic cells from prokaryotes. The theory explains that some organelles such as MITOCHONDRIA and CHLOROPLAST found in eukaryotic cells were once free-living prokaryotes. This theory was based on certain evidences that backed up the claim that chloroplasts were endosymbiont i.e a cell that lived in another cell. The evidences include:
- Chloroplasts have their own genome whose circular structure of DNA is identical to that of bacterial DNA.
- Chloroplasts replicate and divide through fission, the way bacteria divide
- Chloroplasts can be affected by antibiotics, a class of drugs that target bacteria.
However, among these evidences, the possession of flagella or cilia by chloroplasts is not included.
