Question

a.the nucleolus
b.transport vesicles
c. mitochondria
d.ribosomes
e. No organelles are found inside of other organelles.

Answer 1

Ribosomes are the organelles that might be found inside other organelles such as mitochondria. The nucleolus is involved in ribosome assembly but is not inside other organelles, while mitochondria, which contain ribosomes and have their own DNA, are considered the power plants of the cell and support the endosymbiotic theory.

Step-by-step explanation:

Regarding which organelles might be found inside other organelles, the answer is ribosomes. Ribosomes can be found within other cell components; specifically, they can be found inside mitochondria and chloroplasts. The nucleolus is where ribosome assembly begins within the nucleus but is not an organelle contained within another organelle. Transport vesicles are used for moving materials within the cell, rather than being housed inside other organelles. Mitochondria, referred to as the cell's power plants due to their role in ATP production, do not reside inside other organelles.

Endosymbiotic theory relates to mitochondria and suggests that mitochondria were once independent prokaryotic organisms that were engulfed by an ancestral eukaryotic cell. One piece of evidence supporting this theory is the fact that mitochondria have their own DNA and ribosomes, similar to those found in prokaryotic cells.
