Multiple Choice
Which of the following characteristics clearly marks fungi as eukaryotes?
A
Presence of membrane-bound organelles
B
Ability to photosynthesize
C
Prokaryotic cell structure
D
Cell walls composed of peptidoglycan
Verified step by step guidance
1
Understand the key difference between eukaryotic and prokaryotic cells. Eukaryotic cells have membrane-bound organelles (e.g., nucleus, mitochondria), while prokaryotic cells lack these structures.
Recall that fungi are classified as eukaryotes. This means they must possess membrane-bound organelles, which is a defining feature of eukaryotic cells.
Analyze the options provided: 'Presence of membrane-bound organelles' aligns with the characteristics of eukaryotes, while 'Prokaryotic cell structure' is incorrect because fungi are not prokaryotes.
Evaluate the other options: 'Ability to photosynthesize' is not a universal characteristic of fungi, as most fungi are heterotrophic and do not perform photosynthesis. 'Cell walls composed of peptidoglycan' is incorrect because peptidoglycan is found in bacterial cell walls, not in fungi. Fungal cell walls are primarily composed of chitin.
Conclude that the correct answer is 'Presence of membrane-bound organelles,' as this is the characteristic that clearly marks fungi as eukaryotes.
