  • 6. 

    Which organelle holds the cells genetic material and is in charge of cellular reproduction and growth?

    • Nucleolus

    • Ribosome

    • Rough endoplasmic reticulum

    • Nucleus

    Correct Answer
    A. Nucleus
    Explanation
    The nucleus holds the cell's genetic material, which is responsible for controlling cellular reproduction and growth. It contains the DNA and RNA necessary for these processes. The nucleolus, located within the nucleus, is involved in the production of ribosomes, which are responsible for protein synthesis. The other options, ribosome and rough endoplasmic reticulum, are involved in protein synthesis and transportation, respectively, but do not directly hold the cell's genetic material or have a primary role in cellular reproduction and growth.

    Rate this question:

  • 7. 

    Which Cellular component is accountable for protein synthesis from amino acids?  

    • Smooth endoplasmic reticulum

    • Ribosome

    • Golgi Apparatus

    • Nucleus

    Correct Answer
    A. Ribosome
    Explanation
    Ribosomes are responsible for protein synthesis from amino acids. They are small, spherical organelles found either free in the cytoplasm or attached to the rough endoplasmic reticulum. Ribosomes read the genetic information in mRNA and use it to assemble amino acids into a polypeptide chain, which then folds into a functional protein. Thus, ribosomes play a crucial role in the synthesis of proteins within cells.

    Rate this question:

  • 8. 

    A collective group of filaments that provides support for and helps the cell conserve its shape.

    • Cytoplasm

    • Centriole

    • Cytoskeleton

    • Cell membrane

    Correct Answer
    A. Cytoskeleton
    Explanation
    The cytoskeleton is a collective group of filaments within the cell that provides support and helps maintain the cell's shape. It is responsible for organizing the cell's internal structure and plays a crucial role in cell movement, division, and maintaining cell integrity. The cytoskeleton is composed of three main types of filaments: microfilaments, intermediate filaments, and microtubules. These filaments work together to provide structural support and allow for cell motility and shape changes. Therefore, the cytoskeleton is the correct answer as it fits the description given in the question.

    Which organelle is responsible for producing lipids, membrane phospholipids, calcium concentration regulation?

    • Smooth endoplasmic reticulum

    • Golgi complex

    • Rough endoplasmic reticulum

    • Nucleus

    Correct Answer
    A. Smooth endoplasmic reticulum
    Explanation
    The smooth endoplasmic reticulum is responsible for producing lipids, including membrane phospholipids. It also plays a role in regulating calcium concentration within the cell. The Golgi complex is involved in modifying, sorting, and packaging proteins and lipids. The rough endoplasmic reticulum is responsible for protein synthesis. The nucleus contains the cell's genetic material and is not directly involved in lipid production or calcium regulation.

    • Rough Endoplasmic Reticulum

    • Smooth Endoplasmic Reticulum

    • Ribosomes

    • Mitochondria

    Correct Answer
    A. Rough Endoplasmic Reticulum
    Explanation
    The rough endoplasmic reticulum (ER) is responsible for the synthesis and packaging of proteins. It contains ribosomes, which are responsible for protein synthesis. The rough ER is involved in the production of proteins that are intended for secretion or for use in the cell membrane. It works together with the Golgi apparatus in transporting these newly synthesized proteins to their designated locations within the cell. The smooth ER, on the other hand, is involved in lipid metabolism and detoxification. Mitochondria are responsible for energy production in the cell and do not play a direct role in protein synthesis or secretion.

    What is the phase in the cellular reproduction of animals in which the sister chromatids separate?

    • Metaphase

    • Telophase

    • Anaphase

    • Prophase

    Correct Answer
    A. Anaphase
    Explanation
    Anaphase is the phase in the reproduction of animals in which the sister chromatids separate. During anaphase, the microtubules attached to the sister chromatids shorten, pulling them apart and towards opposite ends of the cell. This ensures that each new daughter cell receives a complete set of chromosomes. This phase is characterized by the visible movement of the separated chromatids towards the poles of the cell.

    Circular parts of DNA which compel bacteria to adapt  

    • Pilus

    • Nucleoid

    • Ribosome

    • Plasmid

    Correct Answer
    A. Plasmid
    Explanation
    Plasmids are small, circular DNA molecules that are separate from the bacterial chromosome. They can replicate independently and are often found in bacteria. Plasmids can carry genes that provide advantages to the bacteria, such as antibiotic resistance or the ability to break down certain substances. These genes can be transferred between bacteria through a process called horizontal gene transfer. Plasmids can therefore play a role in bacterial adaptation by providing the bacteria with new genetic material that allows them to survive and thrive in changing environments.

    • Mitochondria

    • Golgi Complex

    • Rough Endoplasmic Reticulum

    • Smooth Endoplasmic Reticulum

    Correct Answer
    A. Smooth Endoplasmic Reticulum
    Explanation
    The smooth endoplasmic reticulum is responsible for metabolizing carbohydrates and steroids, as well as detoxification processes. It also plays a role in regulating the concentration of calcium in the cell. Additionally, the smooth endoplasmic reticulum produces steroids and fats, and attaches receptors on the proteins of the cell membrane. Therefore, the smooth endoplasmic reticulum is the cellular component that performs all of these functions.
