1. Membrane-Bound Organelles:
* Nucleus: Contains the cell's genetic material (DNA) enclosed in a membrane.
* Endoplasmic Reticulum (ER): A network of interconnected membranes involved in protein synthesis, lipid synthesis, and detoxification.
* Golgi Apparatus: Stacks of flattened membrane-bound sacs that process and package proteins and lipids.
* Mitochondria: Powerhouse of the cell, responsible for cellular respiration and energy production.
* Lysosomes: Contain enzymes that break down waste products and cellular debris.
* Peroxisomes: Small, membrane-bound organelles involved in detoxification and lipid metabolism.
2. Cytoskeleton:
* A network of protein filaments that provide structural support, aid in cell movement, and facilitate intracellular transport.
3. Linear DNA:
* Eukaryotic DNA is organized into linear chromosomes, while prokaryotic DNA is circular.
4. Larger Size:
* Eukaryotic cells are generally much larger than prokaryotic cells.
5. Cell Division by Mitosis and Meiosis:
* Eukaryotes divide through mitosis for growth and repair, and through meiosis for sexual reproduction. Prokaryotes divide through binary fission.
6. Compartmentalization:
* Eukaryotic cells have a high degree of internal compartmentalization, which allows for specialized functions within different organelles.
In summary: Eukaryotic cells are more complex and structurally organized than prokaryotic cells, which enables them to carry out a wider range of functions and adapt to diverse environments.
