Study Notes
Prokaryote vs. Eukaryote
- Cell Type: Prokaryotes lack a nucleus and other membrane-bound organelles. Eukaryotes have a nucleus and other membrane-bound organelles.
- Cell Wall: Many prokaryotes have a cell wall, while some eukaryotes (like plants and fungi) also have cell walls. Animal cells lack cell walls.
- Body Type: Prokaryotes are unicellular organisms. Eukaryotes can be unicellular or multicellular.
- Nutrition: Prokaryotes can be autotrophic (make their own food) or heterotrophic (consume food from other organisms). Eukaryotes can be autotrophic, heterotrophic, or a combination.
- Reproduction: Both prokaryotes and eukaryotes can reproduce asexually, but eukaryotes can also reproduce sexually.
Nuclear Membrane
- Prokaryotes lack a nuclear membrane, while eukaryotes have a nuclear membrane that encloses the cell's DNA.
- Prokaryotes have a single copy of chromosomal DNA, while eukaryotes have multiple copies of chromosomal DNA.
