## TL;DR

Cell structure includes membranes, cytoplasm, genetic material, and specialized eukaryotic organelles. This repair keeps biology claims mapped to textbook and reference sources.

## Core Explanation

The old public article had weak verified coverage. This version narrows to three source-backed facts about basic cell organization, eukaryotic nucleus, and mitochondria.
