True or false: Nerve cells have chloroplasts to quickly receive and deliver messages.

False. Nerve cells do not have chloroplasts to quickly receive and deliver messages.


The reason why the statement is false is as follows.


Chloroplasts are organelles that are found in the cells of autotrophs. Multicellular organisms that would have nerves are not autotrophic. Chlorophyll is housed in the thylakoid membranes of chloroplasts. Chlorophyll is a green pigment. The function of chlorophyll is to capture sunlight energy that is used during photosynthesis. Photosynthesisis the...

The reason why the statement is false is as follows.


Chloroplasts are organelles that are found in the cells of autotrophs. Multicellular organisms that would have nerves are not autotrophic. Chlorophyll is housed in the thylakoid membranes of chloroplasts. Chlorophyll is a green pigment. The function of chlorophyll is to capture sunlight energy that is used during photosynthesis. Photosynthesis is the process by which carbon dioxide gas and water are converted into oxygen gas and a sugar that is called glucose.


Thus, chloroplasts are used for photosynthesis within autotrophs. Chloroplasts are not used to deliver messages between nerve cells.


It is the dendrites and axons of a nerve cell that receive and deliver messages (electrical impulses).
