Hi everyone.
Mitochondria and chloroplasts have their own ribosome that is the 70s but According to endosymbiont theory, chloroplast and mitochondria are evolved from prokaryotes so it is a prokaryotic feature. But they live as endosymbionts in eukaryotes. I think option C is correct, but chloroplast and mitochondria are present in eukaryotes so it may be an Eukaryotic feature.

Chlotoplasts and Mitochondria are supposed to be decendents of bacteria so they have their own 70s ribosomes. 70s has 2 subunits 30s and 50s. The mRna moves between the two subunts during translation.
Eukaryotes do not have gas vacuoles so the correct optuon is D.
Eukaryotes do not have gas vacuoles so the correct optuon is D.

Eukaryotes ribosomes synthesized from the nucleus are 80s type but Mitochondria have their own Ribosomes, which are 70S Ribosomes.
So the answer is 'D' only.
So the answer is 'D' only.

Eukaryotic bacteria contents 80's Ribosomes which are usually bounds to membranes if endiplasmic reticulum not the mitochondria.

Gas vacuoles present in plant cell which is eukaryotes. Eukaryotes contains 80S ribosome not 70s.
So the answer is "C".
So the answer is "C".

No, answer is correct, all are true regarding eukaryotes.
Eukaryotes don't have a cell wall in case of animals.

The answer is C not D because eukaryotic do not have gas vacuoles and eukaryotic cells have 80s ribosome not 70s.

The answer is C as eukaryotes contain 80s ribosomes and prokaryotes have 70s ribosomes.

Eukaryotic cells contain 80S ribosomes, thats why the answer is C.

Gas vacuoles ar present in some bacteria. It Helps in floating.
