Question
Based on current evidence, one of the events leading from the first eukaryotic common ancestor to the modern eukaryotic cell would be:Question 9Select one:a.A vesicle forms in the cytoplasm of an Archaea and forms the outer membrane of the mitochondria.b.A vesicle forms in the cytoplasm of a cyanobacterium and forms the inner membrane of the mitochondria.c.A vesicle forms in the cytoplasm of a bacterium and forms the outer membrane of the mitochondria.d.A vesicle forms in the cytoplasm of a cyanobacterium and forms the outer membrane of the mitochondria.
Solution
The correct answer is c. A vesicle forms in the cytoplasm of a bacterium and forms the outer membrane of the mitochondria. This is based on the endosymbiotic theory, which suggests that mitochondria were once free-living bacteria that were engulfed by a primitive eukaryotic cell. Over time, the engulfed bacteria became a symbiotic part of the cell, evolving into the mitochondria we see in eukaryotic cells today. The outer membrane of the mitochondria is thought to be derived from the host cell's membrane, while the inner membrane is derived from the engulfed bacterium.

What components of the modern eukaryotic cell supports the archaeal origin of the eukaryotic cell.
irst appeared during the Paleoproterozoic era, likely as flagellated cells. The prevailing evolutionary hypothesis is that they arose through symbiogenesis between an anaerobic Asgard archaean and an aerobic proteobacterium, leading to the formation of mitochondria. A subsequent symbiogenesis event with a cyanobacterium gave rise to plants, incorporating chloroplasts. Eukaryotic cells possess membrane-bound organelles like the nucleus, endoplasmic reticulum, and Golgi apparatus. Eukaryotes can exist as unicellular or multicellular organisms. In contrast, prokaryotes are typically unicellular. Unicellular eukaryotes are sometimes referred to
