Question

body systems
consider the functions of the digestive system. which organelle has a function most like that of the digestive system?
a vacuoles store materials much like the digestive system does for the body.
b the ribosomes assemble proteins for the cell like the digestive system does for the body.
c the endoplasmic reticulum moves materials throughout the cell as the digestive system moves nutrients throughout the body.
d the mitochondria breaks down food nutrients into usable energy for the cell, just as the digestive system does for the body.

Explanation:

The digestive system breaks down food into usable nutrients. Mitochondria break down food nutrients into usable energy for the cell. This is a functional analogy. Vacuoles store materials (more like storage in the body, not digestion). Ribosomes assemble proteins (not related to digestion). Endoplasmic reticulum transports materials (transport, not digestion).

Answer:

D. The mitochondria breaks down food nutrients into usable energy for the cell, just as the digestive system does for the body.
