Eukaryotic Structures NOT Found in Prokaryotes:
* Nucleus: Contains the cell's DNA, which is organized into chromosomes.
* Nuclear Envelope: A double membrane surrounding the nucleus, regulating what enters and exits.
* Nucleolus: A dense region within the nucleus where ribosome assembly occurs.
* Endoplasmic Reticulum (ER): A network of interconnected membranes involved in protein synthesis, lipid synthesis, and detoxification.
* Golgi Apparatus: A stack of flattened sacs that modify, sort, and package proteins and lipids.
* Lysosomes: Membrane-bound organelles containing enzymes for breaking down cellular waste and debris.
* Mitochondria: The "powerhouse" of the cell, responsible for cellular respiration and ATP production.
* Chloroplasts (in plants): Sites of photosynthesis, where light energy is converted into chemical energy.
* Vacuoles: Large, fluid-filled sacs that store water, nutrients, and waste products.
* Cytoskeleton: A network of protein fibers that provide support, shape, and movement.
Key Differences Between Prokaryotic and Eukaryotic Cells:
* Genetic Material: Prokaryotic DNA is located in a region called the nucleoid, which is not enclosed by a membrane. Eukaryotic DNA is contained within a true nucleus.
* Organelles: Prokaryotes lack the complex, membrane-bound organelles found in eukaryotic cells.
* Size: Eukaryotic cells are generally larger than prokaryotic cells.
