Prokaryotic vs Eukaryotic Cells

Ever wondered why bacteria and human cells are so different? It's all about their internal structure! Prokaryotic cells (like bacteria) are simpler and much smaller than eukaryotic cells (found in plants, animals and fungi).

Both cell types share some basic features - they both have a cell membrane, cytoplasm, and ribosomes for making proteins. However, eukaryotic cells contain membrane-bound organelles that prokaryotes lack. The most important difference is that eukaryotic cells have a nucleus that houses their DNA, while prokaryotic cells have their genetic material floating freely in a region called the nucleoid.

Eukaryotic cells also contain mitochondria (the powerhouse of the cell), and plant cells have chloroplasts for photosynthesis. Prokaryotes lack these structures completely. Additionally, many prokaryotes have a cell wall and some have flagella for movement, while eukaryotes may have permanent vacuoles for storage.

Did you know? Eukaryotic cells are typically 10-100 times larger than prokaryotic cells! This size difference allows eukaryotic organisms to form complex multicellular life, while prokaryotes remain unicellular.
