  • 2. 

    Directs all cell activities

    • Cell membrane

    • Nucleus

    • Mitochondria

    • Lysosomes

    • Endoplasmic reticulum

    • Cell wall

    Correct Answer
    A. Nucleus
    Explanation
    The nucleus is the control center of the cell and directs all cell activities. It contains the cell's genetic material, DNA, which carries instructions for making proteins and controlling cell functions. The nucleus also regulates the cell's growth, reproduction, and metabolism. It is surrounded by a nuclear membrane that protects the DNA and separates it from the rest of the cell. The other options listed, such as the cell membrane, mitochondria, lysosomes, endoplasmic reticulum, and cell wall, all have important functions in the cell but do not directly control all cell activities like the nucleus does.

    Rate this question:

  • 3. 

    The ___ is a gelatinlike material inside the cell membrane

    • Cellulose

    • Chlorophyll

    • Chromatin

    • Cytoplasm

    Correct Answer
    A. Cytoplasm
    Explanation
    Cytoplasm is the correct answer because it is a gelatinlike material that is found inside the cell membrane. It is a fluid substance that fills the cell and contains various organelles, such as the nucleus, mitochondria, and ribosomes. Cytoplasm is responsible for supporting and protecting the organelles within the cell and facilitating various cellular processes, such as metabolism and cell division.

    • Nucleus

    • Nucleolus

    • Cell wall

    • Cell membrane

    • Golgi body

    • Mitochondria

    • Rough endoplasmic reticulum

    • Smooth endoplasmic reticulum

    • Ribosomes

    • Cytoplasm

  • 5. 

    Protects the plant cell

    • Cell membrane

    • Nucleus

    • Mitochondria

    • Lysosomes

    • Endoplasmic reticulum

    • Cell wall

    Correct Answer
    A. Cell wall
    Explanation
    The cell wall is a rigid layer that surrounds the plant cell, providing structural support and protection. It helps maintain the shape of the cell and protects it from external stresses and pathogens. Unlike the cell membrane, which is selectively permeable, the cell wall is permeable to water and other substances. The nucleus, mitochondria, lysosomes, and endoplasmic reticulum are all organelles within the cell that have specific functions, but they do not directly protect the plant cell like the cell wall does.

    Rate this question:

  • 6. 

    The chemical that contains the code for the cell's sturcture and activities is ___.

    • Chlorophyl

    • DNA

    • RNA

    • Anti-viral

    Correct Answer
    A. DNA
    Explanation
    DNA, or deoxyribonucleic acid, is the correct answer because it contains the genetic code that determines the structure and activities of a cell. DNA is located in the nucleus of a cell and is responsible for transmitting hereditary information from one generation to the next. It contains the instructions for building and maintaining an organism, including the production of proteins that are essential for cellular functions. DNA is composed of nucleotides, which are made up of a sugar, a phosphate group, and a nitrogenous base. The sequence of these bases in the DNA molecule determines the specific traits and characteristics of an organism.

  • 7. 

    Allows certain materials to move into and out of the cell

    • Cell membrane

    • Nucleus

    • Mitochondria

    • Lysosomes

    • Endoplasmic reticulum

    • Cell wall

    Correct Answer
    A. Cell membrane
    Explanation
    The cell membrane is responsible for allowing certain materials to move into and out of the cell. It acts as a barrier, controlling the passage of substances in and out of the cell. This selective permeability allows essential molecules like nutrients and oxygen to enter the cell, while waste products and other substances are expelled. The cell membrane also plays a crucial role in maintaining the cell's internal environment and protecting it from external factors.

    Rate this question:

  • 8. 

    Organelles that package cellular substances for export are ___.

    • Golgi bodies

    • Lysosomes

    • Ribosomes

    • Chloroplasts

    Correct Answer
    A. Golgi bodies
    Explanation
    Golgi bodies are responsible for packaging cellular substances for export. They receive proteins and lipids from the endoplasmic reticulum and modify them, sorting and packaging them into vesicles. These vesicles are then transported to the cell membrane, where they fuse and release their contents outside the cell. Therefore, Golgi bodies are the organelles that perform this important function of packaging and exporting cellular substances.

    Rate this question:

  • 9. 

    Organelles that digest food molecules and wastes inside the cells

    • Golgi bodies

    • Lysosomes

    • Ribosomes

    • Chloroplasts

    Correct Answer
    A. Lysosomes
    Explanation
    Lysosomes are organelles that digest food molecules and wastes inside the cells. They contain digestive enzymes that break down various substances, including proteins, carbohydrates, and lipids. Lysosomes also play a role in recycling cellular components and removing damaged organelles. They are responsible for maintaining the overall health and cleanliness of the cell by breaking down and recycling waste materials. Therefore, lysosomes are the correct answer for this question.

    Organelles where energy is released from food molecules

    • Cell membrane

    • Nucleus

    • Mitochondria

    • Lysosomes

    • Endoplasmic reticulum

    Mitochondria are organelles where energy is released from food molecules through a process called cellular respiration. They are often referred to as the "powerhouses" of the cell because they produce adenosine triphosphate (ATP), which is the main energy currency of the cell. Mitochondria have a highly folded inner membrane that allows for efficient production of ATP. This process occurs in eukaryotic cells, where mitochondria are present, and is essential for the cell's functioning and survival.

    • Chlorophyll

    • Chloroplasts

    • Cytoplasm

    • Cellulose

    Correct Answer
    A. Chlorophyll
    Explanation
    Chlorophyll is the pigment in plants that captures light energy and is responsible for photosynthesis. It is located in the chloroplasts, which are the organelles in plant cells where photosynthesis takes place. Chlorophyll absorbs light energy and uses it to convert carbon dioxide and water into glucose, a sugar molecule that serves as food for the plant. Cytoplasm, on the other hand, is the gel-like substance that fills the cell, and cellulose is a structural component of plant cell walls.

    Organelles that digest food molecules and wastes inside the cells

    • Cell membrane

    • Nucleus

    • Mitochondria

    • Lysosomes

    • Endoplasmic reticulum

    • Cell wall

    Correct Answer
    A. Lysosomes
