Abyssal plain consists of uneven surface of oceanic crust covered by fine grain sediments such as clay and silt. They have major reserve of deep ocean biodiversity.

An abyssal plain is an underwater plain on the deep ocean floor, usually found at the depths between 3000 and 6000 m. Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface. They are among the flattest, smoothest, and least explored regions on Earth.

Common to all cells (prokaryotes and eukaryotes), the ribosome (and especially its composition) varies according to the organisms, even if it is always composed of two distinct subunits.

The ribosome is a huge ribonucleoprotein complex that allows the translation of mRNAs into proteins.
