Structures:
* Plasma membrane: A phospholipid bilayer that encloses the cell, regulating what enters and leaves.
* Cytoplasm: The gel-like substance that fills the cell and contains various organelles and molecules.
* Ribosomes: Essential for protein synthesis.
* DNA: The genetic material that carries the cell's instructions.
* RNA: A molecule that plays a key role in protein synthesis.
Processes:
* Cellular Respiration: The process of breaking down glucose to produce energy.
* Transcription: The process of copying DNA into RNA.
* Translation: The process of using RNA to build proteins.
Key Differences:
While these structures and processes are found in both eukaryotes and prokaryotes, there are significant differences between them:
* Eukaryotic cells are generally much larger and more complex than prokaryotic cells.
* Eukaryotic cells have a membrane-bound nucleus that contains their DNA, while prokaryotic cells lack a nucleus and have their DNA located in a region called the nucleoid.
* Eukaryotic cells have a variety of membrane-bound organelles, such as mitochondria, chloroplasts (in plants), endoplasmic reticulum, Golgi apparatus, etc. Prokaryotic cells lack these organelles.
