Chloroplasts are least affected by the absence of sunlight.
Chloroplasts are a plastid that contains chlorophyll and in which photosynthesis takes place. Chloroplasts are highly dynamic. They circulate and are moved around within plant cells, and occasionally pinch in two to reproduce.
EXPLANATION: Desulforudis Audaxviator is a monotypic bacteria found in the gold mines of South Africa living at depths of about 1.86 miles below the Earth's surface. It is almost four centimeters in length and survives on the chemical food sources from the radioactive decay of minerals. It doesn't need sunlight for its existence and is known as the only species to be alone in the ecosystem. It is also known as D. audaxviator and has genes for extracting carbon from dissolved carbon dioxide.
It involves inserting a long needle to extract fetal cells from the fetus's surrounding fluid for these diagnostic purposes. It is a risky procedure that has since been widely replaced by cell-free DNA testing.
