This question is describing the organelles found in a cell. An organelle is a structure that performs a specific FUNCTION (1) in a cell. There are different kinds of organelles with each possessing its own peculiar function. Some of them are as follows:
- NUCLEUS, which is regarded as the brain of a cell because it directs or controls a cell's activities just like the brain of an organism does.
- MITOCHONDRIA is an organelle that produces the energy storing compound called ATP (adenosine triphosphate), hence, it is called power house of the cell.
- CHLOROPLAST is an organelle found in plant cells that functions in the conversion of light energy (from sun) into GLUCOSE (chemical energy) in a process called PHOTOSYNTHESIS.
- RIBOSOMES is an organelle found in both prokaryotic and eukaryotic cells that serves as the site of PROTEIN production in a cell.
<span>Of these choices, neuronal communication between the brain and the muscles of the leg is best conceptualized as electrical and chemical signaling.
The brain sends signals of the electrical and chemical type to reach the leg and move its muscles. Once these signals get to the muscles of the leg, they are moved into motion as a result of the brain "ordering" the leg to move so that a person could get up or get to another place.
