In the context of prokaryotes vs. eukaryotes, which type of cell is generally more structurally complex?
A
Prokaryotic cells, because they are always larger and have more DNA than eukaryotic cells
B
Prokaryotic cells, because they have a nucleus and extensive internal compartmentalization
C
Both are equally complex because both have membrane-bound organelles and linear chromosomes
D
Eukaryotic cells, because they contain membrane-bound organelles and a nucleus
검증된 단계별 안내1
Step 1: Understand the basic structural differences between prokaryotic and eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
Step 2: Recognize that eukaryotic cells contain a nucleus, which houses their DNA, and various membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, contributing to their complexity.
Step 3: Note that prokaryotic cells generally have circular DNA located in a nucleoid region, and they do not have internal compartments separated by membranes.
Step 4: Compare the size and DNA content: prokaryotic cells are usually smaller and have less DNA than eukaryotic cells, which contradicts the incorrect options stating the opposite.
Step 5: Conclude that eukaryotic cells are more structurally complex due to their compartmentalization and presence of a nucleus, which allows for specialized functions within the cell.
