Answer:

The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.

Answer:

The correct answer is glands.

Explanation:

It is known that brain monitors movement, therefore, one can definitely correlate movement of muscles with the brain that comprises the role of sensory and motor neurons. When a stimulus is obtained by the sensory organs, it is transmitted by the sensory neuron to the brain and from their information is further conducted to the effector organs like muscles by the motor neuron. The glands are the group of cells, which takes part in the secretions when instigated by any particular hormone.
