Plasmid DNA, organelles that are not membrane bound, a capsule, mesosomes etc.
Eukaryotes have a nucleus and membrane-bound organelles, such as mitochondria and endoplasmic reticulum, which prokaryotes lack. Eukaryotes also have linear chromosomes, while prokaryotes have circular chromosomes. Additionally, eukaryotes often have multicellular organization, which is less common in prokaryotes.
Since you asked about the main organelle, singular, I will have to say....The membrane bound nucleus that eukaryotes have and prokaryotes do not.
The biggest difference between prokaryotes and eukaryotes is the presence of a distinct nucleus in eukaryotes, which houses the genetic material. Prokaryotes lack a nucleus and their genetic material is located in the cytoplasm. Eukaryotes also have membrane-bound organelles, whereas prokaryotes do not.
Prokaryotes lack a nucleus and membrane-bound organelles, while eukaryotes have both. Prokaryotes typically have a single circular chromosome, while eukaryotes have multiple linear chromosomes. Additionally, prokaryotes tend to be smaller and simpler in structure compared to eukaryotic cells.
No, eukaryotes do have a true nucleus and organelles. What you're describing is a prokaryote.
Bacteria lack nuclear membranes, but they're called prokaryotes, not eukaryotes.
endoplasmic reticulum
Prokaryotes lack a nucleus.Eukaryotes have a nucleus.
Eukaryotes have a nucleus and membrane-bound organelles, such as mitochondria and endoplasmic reticulum, which prokaryotes lack. Eukaryotes also have linear chromosomes, while prokaryotes have circular chromosomes. Additionally, eukaryotes often have multicellular organization, which is less common in prokaryotes.
Since you asked about the main organelle, singular, I will have to say....The membrane bound nucleus that eukaryotes have and prokaryotes do not.
Eukaryotes have a defined nucleus and membrane-bound organelles, while prokaryotes lack a nucleus and organelles. Eukaryotes are typically larger and more complex than prokaryotes.
It is in eukariyotes. Mitochondria is an organelle
Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles, while eukaryotes have a true nucleus and membrane-bound organelles. Eukaryotes are typically more complex and can be single-celled or multicellular, while prokaryotes are only single-celled.
The biggest difference between prokaryotes and eukaryotes is the presence of a distinct nucleus in eukaryotes, which houses the genetic material. Prokaryotes lack a nucleus and their genetic material is located in the cytoplasm. Eukaryotes also have membrane-bound organelles, whereas prokaryotes do not.
Eukaryotes are characterized by having a nucleus in their cells. Prokaryotic cells do not have this organelle, and their genetic material is located in the cell membrane instead.
Prokaryotes lack a nucleus and membrane-bound organelles, while eukaryotes have both. Prokaryotes typically have a single circular chromosome, while eukaryotes have multiple linear chromosomes. Additionally, prokaryotes tend to be smaller and simpler in structure compared to eukaryotic cells.
Eukaryotes have membrane-bound organelles such as the nucleus, endoplasmic reticulum, Golgi apparatus, and mitochondria, which prokaryotes lack. Eukaryotes also have a cytoskeleton for structural support and transport, which is absent in prokaryotes. Additionally, eukaryotes have a more complex and organized internal structure compared to prokaryotes.
