Receiving sensory information and carrying commands to the muscles.
Explanation:
The spinal cord serves as the transmission conduit for the passage of action potential as sensory information through the sensory/afferent neurons to the dorsal roots of the spinal cord.The information synapse with the inter neurons,branching off to the brain and emerged as the response through the motor/efferent neurons to the effectors(muscles).
This pathways is called reflex arc. Thus most of the involuntary action of the body is conducted through the spinal cord

Answer: Chloroplast
Explanation:
The presence of chloroplast would have been the last organelle which appeared in the eukaryotic cell. Chloroplast helps in photosynthesis which means prepare food from the inorganic compounds.
But here the cell obtains energy from the organic compounds which states that there is no need of chloroplast in the cell as they obtain energy by hetero tropic mode of nutrition.
Hence, chloroplast is the correct answer.
Both have a sporophyte generation and gametophyte generation. Also both have pollination, sperm cells travel through tube to reach ovule, and fertilization of egg cell with sperm cell produces zygote
