Biology: Cell Structure I Nucleus Medical Media
Nucleus Medical Media・2 minutes read
Cells have common features like a cell membrane, cytoplasm, and DNA, with eukaryotic cells containing organelles like the nucleus, in contrast to prokaryotic cells without a nucleus or membrane-enclosed organelles. Organelles in cells have specific functions, including the nucleus for DNA storage, ribosomes for protein synthesis, and chloroplasts for photosynthesis in plant cells.
Insights
- Eukaryotic cells have a nucleus and organelles, while prokaryotic cells lack a nucleus and membrane-enclosed organelles, distinguishing them in structure and function within organisms.
- Organelles in cells, such as the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, vacuoles, lysosomes, and mitochondria, play essential roles in DNA storage, protein synthesis, material transport, protein modification, waste breakdown, and energy production, highlighting the complexity and specialization of cellular machinery.
