GCSE Biology Revision "Eukaryotes and Prokaryotes"
Freesciencelessons・2 minutes read
Eukaryotic cells have genetic material enclosed in a nucleus, while prokaryotic cells lack a nucleus and have genetic material in a single loop of DNA, in addition to being smaller and featuring a bacterial cell wall.
Insights
- Eukaryotic cells, present in animals and plants, have DNA enclosed in a nucleus, along with a cell membrane and cytoplasm, distinguishing them from prokaryotic cells.
- Prokaryotic cells, such as bacteria, lack a nucleus and have DNA in a single loop, in addition to being smaller, possessing a cell membrane, cell wall, and cytoplasm.

Cell Structure: Eukaryotic vs. Prokaryotic Differences
- Eukaryotic cells, found in animals and plants, have genetic material enclosed in a nucleus, defined as cells containing DNA within a nucleus. They also feature a cell membrane and cytoplasm, distinct from a cell wall.
- Prokaryotic cells, like bacteria, lack a nucleus, with genetic material in a single loop of DNA. They are notably smaller than eukaryotic cells, possess a cell membrane, a bacterial cell wall, and cytoplasm.
