Questions and Answers
  • 1. 

    Which type of cell has a nucleus?

    • A.

      Prokaryote

    • B.

      Eukaryote

    • C.

      Bacteria

    • D.

      All of the above

    Correct Answer
    B. Eukaryote
    Explanation
    Eukaryotes are the type of cells that have a nucleus. Unlike prokaryotes, which do not have a nucleus, eukaryotic cells contain a well-defined nucleus that houses the genetic material. The nucleus is a membrane-bound organelle that stores and protects the DNA. Bacteria, on the other hand, are prokaryotes and lack a nucleus. Therefore, the correct answer is eukaryote.

    Which type of cell does not contain membrane-bound organelles?

    • A.

      Prokaryote

    • B.

      Eukarote

    • C.

      Virus

    • D.

      None of them

    Correct Answer
    A. Prokaryote
    Explanation
    Prokaryotes are the type of cells that do not contain membrane-bound organelles. Unlike eukaryotic cells, prokaryotic cells lack a nucleus and other membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Instead, their genetic material is found in the cytoplasm, floating freely. Prokaryotes include bacteria and archaea, which are single-celled organisms that have simpler internal structures compared to eukaryotes.

  • 3. 

    In a prokaryotic cell, the DNA is ___________. 

    • A.

      Wrapped around histone proteins

    • B.

      Contained in the nucleus

    • C.

      Circular

    • D.

      Found in the nucleoid region

    • E.

      "free floating"

    Correct Answer(s)
    C. Circular
    D. Found in the nucleoid region
    E. "free floating"
    Explanation
    In a prokaryotic cell, the DNA is circular and found in the nucleoid region. Additionally, the DNA is "free floating" in the cytoplasm, meaning it is not contained within a membrane-bound nucleus like in eukaryotic cells. The circular shape of the DNA allows it to fit within the small size of prokaryotic cells. The nucleoid region is a concentrated area within the cytoplasm where the DNA is located, but it is not enclosed within a nucleus.

    Which type of cell is likely the most recently evolved?

    • A.

      Eukaryote

    • B.

      Prokaryote

    • C.

      Both evolved at the same time

    • D.

      None of the above

    Correct Answer
    A. Eukaryote
    Explanation
    Eukaryotes are likely the most recently evolved type of cell because they are more complex and have a nucleus, which prokaryotes do not have. The evolution of eukaryotes is thought to have occurred through a process called endosymbiosis, where a prokaryotic cell engulfed another prokaryotic cell, leading to the development of organelles such as mitochondria and chloroplasts. This suggests that eukaryotes evolved after prokaryotes.

  • 5. 

    Which type of cell has ribosomes?

    • A.

      Prokaryote

    • B.

      Eukaryote

    • C.

      Both prokaryotes & eukaryotes

    • D.

      None of them

    Correct Answer
    C. Both prokaryotes & eukaryotes
    Explanation
    Both prokaryotes and eukaryotes have ribosomes. Ribosomes are responsible for protein synthesis, and they can be found in the cytoplasm of both types of cells. In prokaryotes, ribosomes are smaller and free-floating in the cytoplasm, while in eukaryotes, they can be found both free-floating and attached to the endoplasmic reticulum. This is why the correct answer is both prokaryotes and eukaryotes.

  • 6. 

    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. Eukaryote
    Explanation
    Eukaryote is the correct answer because eukaryotic cells are generally larger and more complex than prokaryotic cells. Eukaryotic cells have a true nucleus and membrane-bound organelles, which allow for compartmentalization and specialization of cellular functions. Prokaryotic cells, on the other hand, lack a true nucleus and membrane-bound organelles, making them generally smaller and less complex. Therefore, eukaryotic cells are considered to be the largest and most complex cell type.

  • 7. 

    Which type of cell is always a single celled organism?

    • A.

      Prokaryote

    • B.

      Eukaryotes

    • C.

      Neither cell is single celled

    • D.

      None of the above

    • E.

      All of them

    Correct Answer
    A. Prokaryote
    Explanation
    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 multicellular organisms. Eukaryotes, on the other hand, can be single-celled or multicellular organisms as they have a nucleus and other membrane-bound organelles. Therefore, the correct answer is prokaryote.

    Rate this question:

  • 8. 

    The DNA of a eukaryotic cell can be found in the _________. 

    • A.

      Nucleoid region

    • B.

      Mitochondria

    • C.

      Nucleus

    • D.

      Cell membrane

    Correct Answer
    C. Nucleus
    Explanation
    The DNA of a eukaryotic cell can be found in the nucleus. The nucleus is a membrane-bound organelle that houses the cell's genetic material, including the DNA. It is responsible for controlling the cell's activities and is involved in processes such as gene expression and replication. The DNA in the nucleus is organized into chromosomes and contains the instructions for building and maintaining the cell and carrying out its functions.

  • 9. 

    Which type of cell contains a cell membrane?

    • A.

      Prokaryote

    • B.

      Eukaryote

    • C.

      Both cell types contain a cell membrane

    • D.

      None of the above

    Correct Answer
    C. Both cell types contain a cell membrane
    Explanation
    Both prokaryote and eukaryote cells contain a cell membrane. The cell membrane is a thin, flexible barrier that surrounds the cell and separates its internal environment from the external environment. It controls the movement of substances in and out of the cell, maintaining homeostasis and protecting the cell's internal components. Prokaryote cells, such as bacteria, have a simple cell structure and lack a nucleus, while eukaryote cells, found in plants, animals, fungi, and protists, have a more complex structure with a nucleus. However, regardless of their differences, both types of cells have a cell membrane.

    Correct Answer(s)
    C. Both have cell membranes
    D. Both have DNA
    E. Both have Ribosomes
    G. Both have a need for producing/using energy
    Explanation
    The given correct answer suggests that the similarities between prokaryotic and eukaryotic cells include having cell membranes, DNA, ribosomes, and a need for producing/using energy. This means that both types of cells have a protective barrier surrounding them, genetic material for carrying instructions, structures responsible for protein synthesis, and a requirement for energy production and utilization.

    • A.

      Animal cells

    • B.

      Plant cells

    • C.

      Bacteria

    Correct Answer(s)
    A. Animal cells
    B. Plant cells
    D. Fungi
    E. Protists
    Explanation
    Eukaryotic cells are characterized by having a true nucleus and membrane-bound organelles. Animal cells, plant cells, fungi, and protists all possess these features, making them eukaryotic. Bacteria, on the other hand, are prokaryotic cells that lack a nucleus and membrane-bound organelles. Therefore, the correct answer is animal cells, plant cells, fungi, and protists.

    Which cell types have/can have cell walls?

    • A.

      Prokaryotes

    • B.

      Eukaryotes

    • C.

      Both prokaryotes and eukaryotes

    • D.

      None of the above

    Correct Answer
    C. Both prokaryotes and eukaryotes
    Explanation
    Both prokaryotes and eukaryotes can have cell walls. Prokaryotes, such as bacteria, have a cell wall made of peptidoglycan, which provides structural support and protection. On the other hand, eukaryotes, including plants, fungi, and some protists, also have cell walls. In plants, the cell wall is primarily composed of cellulose, while in fungi it is made of chitin. The cell wall in eukaryotes serves similar functions, providing rigidity, protection, and support to the cell. Therefore, both prokaryotes and eukaryotes can have cell walls.
