Voici pourquoi:
* noyau: The nucleus is a defining characteristic of eukaryotic cells. It houses the cell's DNA, which controls the cell's activities.
* Membrane-Bound Organelles: These are specialized structures within the cell that are enclosed by membranes. Les exemples incluent les mitochondries (pour la production d'énergie), l'appareil Golgi (pour le traitement des protéines), le réticulum endoplasmique (pour la synthèse des protéines et le métabolisme lipidique) et les lysosomes (pour la dégradation des déchets).
En revanche, cellules procaryotes , such as bacteria and archaea, lack a nucleus and membrane-bound organelles. Their DNA is located in a region called the nucleoid, and they have fewer internal compartments.
