What type of cells lack a nucleus?
This is a biology question, but the answer is Prokaryotic. ------------------------------------------------------------------------------------ Red blood cells also lack a nucleus.
What do all prokaryotic cells have in common?
All prokaryotic cells lack a nucleus and membrane-bound organelles. They typically have a single circular chromosome, a cell wall, and ribosomes for protein synthesis. Prokaryotic cells are also generally smaller and simpler in structure compared to eukaryotic cells.
What distinguishes eukaryotic cells from prokaryotic cells?
Eukaryotic cells have a defined nucleus containing their genetic material, while prokaryotic cells do not. Eukaryotic cells also contain membrane-bound organelles, like mitochondria and endoplasmic reticulum, which are absent in prokaryotic cells. Eukaryotic cells are generally larger and more complex than prokaryotic cells.
Do sloths have prokaryotic cells?
No, sloths do not have prokaryotic cells; they are eukaryotic organisms. All animals, including sloths, are composed of eukaryotic cells, which have a defined nucleus and membrane-bound organelles. Prokaryotic cells, on the other hand, are simpler and lack a nucleus, and they are typically found in bacteria and archaea.
What cell can you see ribosomes but not mitochondria?
Prokariyotes do not have mitochondria. But they have ribosomes
All cells are eukaryotes EXCEPT for what?
Prokaryotic cells, such as bacteria and archaea, are not eukaryotic. These cells lack a distinct nucleus and do not have membrane-bound organelles like eukaryotic cells do.
Do all cells have Golgi bodies?
No, not all cells have Golgi bodies. Golgi bodies are found in eukaryotic cells, where they are involved in modifying, sorting, and packaging proteins for secretion or for use within the cell. Prokaryotic cells typically lack Golgi bodies.
What is a example of a prokaryotic cell?
An example of a prokaryotic cell is a bacterium like Escherichia coli (E. coli). Prokaryotic cells lack a membrane-bound nucleus and other membrane-bound organelles, and their genetic material is found in the nucleoid region within the cytoplasm.
What is the composition of cell?
Prokaryotic cells are, much like eukaryotic cells, filled with proteins, DNA, and other assorted chemicals. However, unlike a eukaryotic cell, prokaryotic cells lack a membrane-bound nucleus, and all its organelles are likewise not membrane bound.
Do prokaryotic cells have flagella?
Not all prokaryotic cells have flagella only some do. The flagella in prokaryotic cells are made up of the hook, filament and basal body.
Which feature is found only in prokaryotic cells?
Prokaryotic cells have a feature called nucleoid, which is a region within the cell that contains the genetic material (DNA). This is not surrounded by a membrane, unlike the nucleus found in eukaryotic cells.
Do all cells have a cell envelope?
No, not all cells have a cell envelope. While many prokaryotic cells (such as bacteria) have a cell envelope composed of a cell wall and cell membrane, eukaryotic cells (such as those in plants and animals) do not have a cell envelope in the same sense. Eukaryotic cells have a plasma membrane but lack a rigid cell wall like prokaryotic cells.
