A prokaryote (/proʊˈkærioʊt, -ət/, also spelled procaryote) is a single-cell organism whose cell lacks a nucleus and other membrane-bound organelles. The...

wall Capsule Pili Marine prokaryotes are marine bacteria and marine archaea. They are defined by their habitat as prokaryotes that live in marine environments...

They constitute a major group of life forms alongside the two groups of prokaryotes: the Bacteria and the Archaea. Eukaryotes represent a small minority...

Phototrophs (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light', and τροφή (trophḗ) 'nourishment') are organisms that carry out photon capture to produce...
