Verified step by step guidance

Begin by understanding the basic differences between prokaryotic and eukaryotic cells. Prokaryotic cells, such as bacteria, lack a nucleus and other membrane-bound organelles, while eukaryotic cells, like those in plants and animals, have a nucleus and various organelles.
Consider the structural complexity of eukaryotic cells. The presence of organelles like mitochondria, endoplasmic reticulum, and Golgi apparatus contribute to their larger size compared to prokaryotic cells.
Examine typical size ranges: Prokaryotic cells usually range from 0.1 to 5 micrometers in diameter, whereas eukaryotic cells typically range from 10 to 100 micrometers.
Reflect on the implications of cell size on function. The smaller size of prokaryotic cells allows for faster growth and reproduction, while the larger size of eukaryotic cells supports complex functions and multicellularity.
Conclude by comparing the size: Prokaryotic cells are generally smaller than eukaryotic cells, which is consistent with their simpler structure and lack of organelles.
