Hint: The organelles which contain their own DNA are the semi-organelles. As compared to the nuclear genes that obey the Mendelian, biparental inheritance, the genes found in semi-autonomous organelles follow cytoplasmic inheritance. This implies that the cytoplasm transmits these genes.
Complete answer:
In most eukaryotic cells that are part of the endomembrane system in the cytoplasm, the Golgi body is an organelle that bundles proteins within the cell into membrane-bound vesicles and lacks their DNA. In lipid transport and lysosome formation, the Golgi apparatus is also involved. Ribosomes are minute particles that are composed of RNA and associated proteins that operate to synthesize proteins and lack DNA as well.
Chloroplast and mitochondria are referred to since semi-autonomous organelles as they have their own DNA with single stranded DNA. As compared to the nuclear genes that follow the Mendelian, biparental inheritance, the genes found in chloroplast and mitochondria follow cytoplasmic inheritance. This implies that the cytoplasm transmits these genes.
They cannot exist independently, because they rely on the nuclear gene for biogenesis and the ground cytoplasm for biosynthetic activities. They are thus classified as semi autonomous organelles.
So, the correct answer is “Option B”.
Note: Depending on the tissue and the organisms, mitochondrial proteins (proteins transcribed from mitochondrial DNA) differ. 615 distinct forms of proteins from cardiac mitochondria have been described in humans. Chloroplasts are extremely dynamic and circulate within plant cells and are passed around and sometimes pinched in two to replicate. Ecological factors such as light color and intensity strongly affect their behavior.
