Final answer:
The statement that eukaryotic cells are more complicated and contain organelles while prokaryotic cells are composed of simpler structures is true. Eukaryotic cells have a nucleus and other organelles that allow for compartmentalization of functions, unlike the simpler prokaryotic cells.
Step-by-step explanation:
It is true that eukaryotic cells are more complicated and contain organelles, while prokaryotic cells are composed of simpler structures. Eukaryotic cells, including those of plants and animals, boast a more complex structure with various organelles like the nucleus, mitochondria, and endoplasmic reticulum allowing them to compartmentalize different functions. The presence of a nucleus, which houses multiple rod-shaped chromosomes, is one of the key differences between eukaryotic and prokaryotic cells, the latter of which do not have a nucleus and typically contain a single, circular chromosome. Prokaryotic cells, such as bacteria and archaea, are generally simpler and lack many of the complex organelles found in eukaryotes. However, prokaryotic cells can often exchange nutrients with the environment more rapidly than eukaryotic cells due to their simpler structures.
