Eukaryotic Cells: Definition, Structure, and Characteristics

Eukaryotic Cells

Eukaryotic cells are complex cells that have a true nucleus enclosed by a membrane, which stores genetic material (DNA). They contain many specialized structures called organelles, such as mitochondria for energy production, ribosomes for making proteins, and, in plant cells, chloroplasts for photosynthesis. Eukaryotic cells are found in animals, plants, fungi, and protists. They are generally larger and more advanced than prokaryotic cells, allowing for greater specialization and complex functions.
