The delta is the landform that is formed by the process of deposition of sediments that are carried by the free flowing rivers from landforms. The delta forms when the river enters into the sea, lake, estuary, ocean, reservoir and also forms when the another kind of river cannot carry away the already deposited sediments from delta.
Eukaryotes are larger cells with membrane-bounded organelles. Prokarotes are not that large and do not have a nucleus or any memberane-bound organelles.
