What is an organelle in a cell synonymous to in an animal?

The similarity between an organelle and an organ lies in
that their function within the bodies in which they operate is very specific. In the
eukaryote cell (the type of cell that is one of the three branches of living beings),
the organelles are different sub-parts within it which carry a specific function to
protect it. Each organelle has an assigned duty within the cell. It can be anything,
from producing the cell's energy (mitochondria), to conducting the process of
homeostasis (vacuole). Also, each organelle works separately for the same purpose: To
maintain the cell alive and functioning well.

Given that
each organelle within the eukaryote cell works for the optimal function and welfare of
the cell, we can compare it to the organs within the human (or animal) body. The human
organs also work, both separately and together, using their own protective ways to
remain healthy. Also in a similar way to the organelles, animal organs have specific
functions. In humans and animals, for example, the heart pumps the blood, carrying air
to the lungs. The lungs, on their part, do the function of providing oxygen to the
entire body and to convert oxygen into the carbon monoxide that we breathe out after
excreting it from the air we breathed in. The liver helps eliminate toxins, and each
intestine is in charge of absorbing nutrients and eliminating
waste.

In smaller words, organelles are the cell's
"organs", and organs are the animal's version of organelles- to put it in a more
colloquial and mundane way. :)
