The absence of a nucleus.
The presence of a membrane-bound nucleus containing genetic material (DNA) is a key observation that proves a cell is a eukaryote. Eukaryotic cells also contain membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
which observation proves that cells is eurkaryote
prokaryote cells
If an organism's cells contain a nucleus that is enclosed by the nuclear envelope, which contains the genetic material, this proves it is a eukaryote. The presence of a nucleus gives eukaryotes their name, which comes from the Greek ευ.
The presence of a nucleus surrounded by a membrane is a key observation that proves a cell is a eukaryote. Eukaryotic cells also typically have membrane-bound organelles, such as mitochondria and endoplasmic reticulum, which are not found in prokaryotic cells. Additionally, eukaryotic cells are generally larger and more complex in structure compared to prokaryotic cells.
Prokaryote
prokaryote
A eukaryote under observation has no membrane to separate the nucleus.
A eukaryote under observation has no membrane to separate the nucleus.
A eukaryote under observation has no membrane to separate the nucleus.
No, only in eurokaryotic cells.
hmm extracellular DNA perhaps? Eukaryotic cells however have lots of things prokaryote cells don't have like a nucleus and mitochondria.
