The main difference between prokaryotic and eukaryotic is that eukaryotic cells contain membrane-bound organelles, such as the nucleus, and prokaryotic cells do not. Prokaryotic cells came in existence first, and eukaryotic cells were a result of evolution. Eukaryotic cells are multicellular, but prokaryotic cells are typically unicellular. Take advantage of this structured quiz learn everything there is to know about prokaryotic and eukaryotic cells.
- 1.
Which type of cell has a nucleus?
- A.
Prokaryote
- B.
Eukaryote
- C.
Bacteria
Correct Answer
B. EukaryoteExplanation
Eukaryotes are the type of cells that have a nucleus. Unlike prokaryotes, which do not have a nucleus, eukaryotic cells have a membrane-bound nucleus that contains the cell's genetic material. The nucleus is responsible for controlling the cell's activities and storing its DNA. Bacteria, on the other hand, are prokaryotes and do not have a nucleus. Therefore, the correct answer is eukaryote.Rate this question:

Which type of cell does not contain membrane-bound organelles?
- A.
Prokaryote
- B.
Eukarote
- C.
Virus
Correct Answer
A. ProkaryoteExplanation
Prokaryote is the correct answer because prokaryotic cells do not have membrane-bound organelles, such as a nucleus, mitochondria, or endoplasmic reticulum. Unlike eukaryotic cells, prokaryotic cells have a simpler structure and lack a true nucleus. They have genetic material floating freely in the cytoplasm and lack membrane-bound compartments.Rate this question:

In a prokaryotic cell, the DNA is ...
- A.
Wrapped around histone proteins
- B.
Contained in the nucleus
- C.
"naked" and "free-floating"
Correct Answer
C. "naked" and "free-floating"Explanation
In prokaryotic cells, the DNA is "naked" and "free-floating" because these cells lack a nucleus and do not have membrane-bound organelles. The DNA in prokaryotes is not associated with histone proteins or contained within a nucleus. Instead, it is found in the cytoplasm, where it exists as a single circular chromosome that is not enclosed by a membrane. This arrangement allows for easier access and regulation of the genetic material in prokaryotic cells.Rate this question:

Which type of cell is likely the most recently evolved?
- A.
Eukaryote
- B.
Prokaryote
- C.
Both evolved at the same time
Correct Answer
A. EukaryoteExplanation
Eukaryotes are likely the most recently evolved type of cell because they are more complex and have a nucleus, which prokaryotes lack. Eukaryotes also have membrane-bound organelles, such as mitochondria and endoplasmic reticulum, which allow for more specialized functions. These characteristics suggest that eukaryotes have undergone more evolutionary changes and adaptations over time compared to prokaryotes, making them the most recently evolved cell type.Rate this question:

Which type of cell has ribosomes?
- A.
Prokaryote
- B.
Eukaryote
- C.
Both prokaryotes & eukaryotes
Correct Answer
C. Both prokaryotes & eukaryotesExplanation
Ribosomes are present in both prokaryotic and eukaryotic cells. Ribosomes are responsible for protein synthesis, and they can be found in the cytoplasm of both types of cells. In prokaryotes, ribosomes are free-floating in the cytoplasm, while in eukaryotes, they can be found in the cytoplasm as well as attached to the endoplasmic reticulum. Therefore, both prokaryotes and eukaryotes have ribosomes.Rate this question:

Which type of cell is considered to be the largest and most complex cell type?
- A.
Prokaryote
- B.
Eukaryote
- C.
Both are the same size and complexity
Correct Answer
B. EukaryoteExplanation
Eukaryote cells are considered to be the largest and most complex cell type. These cells have a nucleus and membrane-bound organelles, which allow for compartmentalization and specialization of different cellular functions. In contrast, prokaryote cells do not have a nucleus or membrane-bound organelles, making them smaller and less complex in structure. Therefore, the correct answer is eukaryote.Rate this question:

Which type of cell is always a single-celled organism?
- A.
Prokaryote
- B.
Eukaryotes
- C.
Neither cell is single-celled
Correct Answer
A. ProkaryoteExplanation
Prokaryotes are always single-celled organisms because they lack a nucleus and other membrane-bound organelles. They are simple in structure and do not have the ability to form complex multicellular organisms. Eukaryotes, on the other hand, can be single-celled or multicellular, as they have a nucleus and other membrane-bound organelles that allow for more complex cellular functions. Therefore, the correct answer is prokaryote.Rate this question:

Where is the DNA of a eukaryotic cell typically located?
- A.
Nucleoid region
- B.
Mitochondria
- C.
Nucleus
Correct Answer
C. NucleusExplanation
In eukaryotic cells, the DNA, which carries the genetic instructions for the cell's functions and development, is typically found within the nucleus. The nucleus is a membrane-bound organelle that serves as the control center of the cell, protecting and organizing the DNA. While eukaryotic cells may also have DNA in other organelles like mitochondria and chloroplasts, the primary repository of the cell's genetic material is within the nucleus.Rate this question:

Which type of cell contains a cell membrane?
- A.
Prokaryote
- B.
Eukaryote
- C.
Both cell types contain a cell membrane
Correct Answer
C. Both cell types contain a cell membraneExplanation
Both prokaryotic and eukaryotic cells contain a cell membrane. The cell membrane is a thin, flexible barrier that surrounds the cell and separates the internal environment from the external environment. It controls the movement of substances in and out of the cell, allowing nutrients to enter and waste products to exit. Prokaryotic cells, which are simpler and lack a nucleus, have a cell membrane as their outermost boundary. Eukaryotic cells, which are more complex and have a nucleus, also have a cell membrane that encloses their organelles and cytoplasm. Therefore, both types of cells contain a cell membrane.Rate this question:

Prokaryotic cells are the oldest cells.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
False. While prokaryotic cells are among the oldest forms of life on Earth, it is not accurate to state that they are the oldest cells overall. The exact origin of life on Earth is still a subject of scientific inquiry, but it is believed that simpler forms of life, such as prokaryotic cells, existed before more complex eukaryotic cells. However, the concept of "oldest cells" is not straightforward, as it depends on the definition and context of "oldest."Rate this question:
