Endoplasmic reticulum
C
Mitochondrion
D
Lysosome
Verified step by step guidance
1
Understand the characteristics of prokaryotic cells: Prokaryotic cells are simpler in structure and lack a nucleus. They have their own DNA, ribosomes, and are capable of independent replication.
Review the structure and function of the mitochondrion: Mitochondria have their own circular DNA, similar to prokaryotic cells, and possess ribosomes that resemble those found in prokaryotes. They also replicate independently through a process similar to binary fission.
Compare the mitochondrion to other organelles listed: The Golgi apparatus, endoplasmic reticulum, and lysosome do not have their own DNA or ribosomes, nor do they replicate independently. These organelles are more integrated into the eukaryotic cell's overall function.
Understand the theory of endosymbiosis: This theory suggests that mitochondria originated from free-living prokaryotic cells that were engulfed by ancestral eukaryotic cells, which explains their prokaryotic-like features.
Conclude that the mitochondrion most closely resembles a prokaryotic cell due to its independent replication, circular DNA, and prokaryotic-like ribosomes.
