B. Prokaryotic cells are typically smaller than eukaryotic cells
C. Prokaryotic cells share certain features
1. Plasma membrane
2. Nucleoid containing DNA
3. Cytoplasn
a. Cytosol: water, dissolved ions, water-soluble macromolecules
b. Ribosomes: Synthesize protein
D. Some prokaryotic cells have specialized features
1. Cell walls
a. Located outside plasma membrane
b. Peptidoclycan
c. Not a major permeable barrier
d. Capsule: slime like coating outside cell-wall for protection in bacteria
2. Internal Membranes
a. Photosynthetic bacteria use internal membranes for energy-releasing reactions
3. Flagella and Pili

b. Pili: adhere to other cells to exchange genetic material, food, protection
4. Cytoskeleton
a. Helical filaments composed of actin to maintain cell shape
No, the vast majority of prokaryotes are not harmful.
Yes, prokaryotes have liquid cytoplasm inside their cells.
Eukaryotes most likely evolved from prokaryotes.
Single-celled organisms that do not have organized nuclei are called prokaryotes. These organisms are simple in structure and lack a membrane-bound nucleus. Examples of prokaryotes include bacteria and archaea.
Since you asked about the main organelle, singular, I will have to say....The membrane bound nucleus that eukaryotes have and prokaryotes do not.
Prokaryotes are part of the Monera kingdom. They have the same characteristics.
Prokaryotes do not have a membrane-bound nucleus or other membrane-bound organelles.
Yes, eukaryotes have a nucleus. On the other hand, prokaryotes do not have a nucleus. Eukaryotes also have numerous other characteristics not found in prokaryotes, the nucleus is simply the most well known.
yes prokaryotes have prokaryotes
Eukaryotic organisms have a defined nucleus and membrane-bound organelles, while prokaryotes lack a nucleus and organelles. Eukaryotes are typically larger and more complex than prokaryotes, with a linear DNA structure and the ability to undergo sexual reproduction.
Bacteria is also known as prokaryotes Bacteria is also known as prokaryotes
The other domain of unicellular prokaryotes is Archaea. Archaea are a distinct group of single-celled organisms that have characteristics of both bacteria and eukaryotes. They are known for their ability to thrive in extreme environments, such as hot springs and deep-sea vents.
Prokaryotes are bacteria.
Bacterium are prokaryotes
Bacterium are prokaryotes
Prokaryotes are singular celled organisms. Bacteria (mainly)are known as Prokaryotes.
prokaryotes have a nucleas
