Overview of Cell Structure
Nucleus Biology・2 minutes read
Cells are the smallest living units with common features like a cell membrane, cytoplasm, and DNA. Eukaryotic cells have organelles like the nucleus, while prokaryotic cells lack a nucleus and membrane-enclosed organelles.
Insights
- Eukaryotic cells, present in plants and animals, contain a nucleus and organelles, while prokaryotic cells, like bacteria, lack a nucleus and membrane-bound organelles, showcasing a fundamental distinction in cellular structure.
- Organelles within cells have specific roles, including the nucleus controlling DNA, ribosomes synthesizing proteins, and mitochondria generating energy, emphasizing the importance of these specialized components in cellular function and survival.
