  • 2. 

    The genetic material of an animal cell is found in the

    • Nucleus

    • Cytoplasm

    • Ribosome

    • Vacuole

    Correct Answer
    A. Nucleus
    Explanation
    DNA (genetic material) is found in the nucleus.

    Rate this question:

  • 3. 
    The structures labeled A, B, C, and D in the following diagram represent - ProProfs

    The structures labeled A, B, C, and D in the following diagram represent

    • Organelles

    • Organs

    • Nuclei

    • Mitochondria

    Correct Answer
    A. Organelles
    Explanation
    A nucleus and mitochondrion is selected, but they all are organelles.

    Rate this question:

  • 4. 

    The cell nucleus functions

    • In obtaining energy for the cell

    • In the storage of digestive enzymes

    • As the center of control for cell metabolism and reproduction

    • In the transport of materials throughout the cell

    Correct Answer
    A. As the center of control for cell metabolism and reproduction
    Explanation
    The nucleus contains DNA, which is necessary for reproduction.

    Rate this question:

  • 5. 

    Mitochondria are organelles in which

    • Digestive enzymes are stored

    • Secretory products are packaged and stored

    • The energy needed by the cell is released from nutrients

    • Protein manufacture occurs

    Correct Answer
    A. The energy needed by the cell is released from nutrients
    Explanation
    The mitochondria release energy from glucose in the form of ATP.

    Rate this question:

  • 6. 

    Which cell organelles are most closely associated with energy changes in a plant?

    • Mitochondria and chromosomes

    • Chloroplasts and mitochondria

    • Chromosomes and nucleus

    • Chloroplasts and nucleus

    Correct Answer
    A. Chloroplasts and mitochondria
    Explanation
    CHLOROPLASTS create glucose using the energy from the sun. MITOCHONDRIA release the energy stored in glucose in the form of ATP.

    Rate this question:

  • 7. 

    Current evidence indicates that ribosomes are most closely associated with 

    • Contraction of the cytoplasm

    • Production of DNA

    • Synthesis of protein

    • Regulation of mitosis

    Correct Answer
    A. Synthesis of protein
    Explanation
    RIBOSOMES make proteins. SYNTHESIS means "to make."

    Rate this question:

  • 8. 

    In both plant and animal cells, the cell membrane 

    • Produces enzymes

    • Controls reproduction

    • Is composed of sugars

    • Regulates diffusion

    Correct Answer
    A. Regulates diffusion
    Explanation
    The cell membrane controls what goes in and out of a cell. Substances get into and out of a cell membrane through the process of diffusion.

    Rate this question:

  • 9. 
    Structure A is most probably a  - ProProfs

    Structure A is most probably a 

    • Mitochondrion

    • Ribosome

    • Vacuole

    • Nucleus

    Correct Answer
    A. Vacuole
    Explanation
    Vacuoles are for storage. That substance is being stored inside the cell in a VACUOLE.

    Rate this question:

  • 10. 

    Which is the most accurate statement concerning protein synthesis in cells?

    • Proteins are synthesized at the mitochondria in all living cells.

    • Proteins are synthesized at the ribosomes in all living cells.

    • Proteins are synthesized at the ribosomes in plant cells only.

    • Proteins are synthesized by nuclei in animal cells only.

    Correct Answer
    A. Proteins are synthesized at the ribosomes in all living cells.
    Explanation
    Proteins are synthesized by the ribosomes. LOOK IN YOUR NOTES!!!
