  1. 1.
    The endoplasmic reticulum primarily functions in
    Show explanation
    The endoplasmic reticulum forms a network of membranes involved in transporting materials and synthesizing proteins and lipids.
  2. 2.
    Which cell organelle is directly responsible for aerobic respiration?
    Show explanation
    Aerobic respiration occurs in the mitochondria where energy is released from food molecules.
  3. 3.
    The nucleolus is mainly involved in the production of
    Show explanation
    The nucleolus synthesizes ribosomal RNA and helps in the formation of ribosomes.
  4. 4.
    Which of the following cell structures is non-living?
    Show explanation
    The cell wall is a non-living structure secreted by the cell, while the other options are living components of the cell.
  5. 5.
    A red blood cell is adapted to its function by lacking a nucleus mainly to
    Show explanation
    Mature red blood cells lose their nucleus to create more space for haemoglobin, thereby increasing oxygen-carrying capacity.
  6. 6.
    The basic unit of life is the?
    Show explanation
    The cell is the smallest structural and functional unit of life.
  7. 7.
    Which of the following is found in both plant and animal cells?
    Show explanation
    Both plant and animal cells have a cell membrane controlling movement of substances.
  8. 8.
    The control center of the cell is the?
    Show explanation
    The nucleus contains genetic material and controls cell activities.
  9. 9.
    The cell membrane is also known as the?
    Show explanation
    The cell membrane is also called the plasma membrane.
  10. 10.
    Which organelle is responsible for photosynthesis?
    Show explanation
    Chloroplast contains chlorophyll and carries out photosynthesis.
  11. 11.
    The jelly-like substance inside the cell is called?
    Show explanation
    Cytoplasm contains organelles and supports cellular activities.
  12. 12.
    Ribosomes are responsible for?
    Show explanation
    Ribosomes are the site of protein synthesis.
  13. 13.
    The structure that gives plant cells a definite shape is the?
    Show explanation
    The rigid cell wall provides shape and support in plant cells.
  14. 14.
    Mitochondria are known as the powerhouse of the cell because they?
    Show explanation
    Mitochondria release energy through respiration in the form of ATP.
  15. 15.
    The movement of substances across the cell membrane without energy is called?
    Show explanation
    Passive transport does not require energy.
  16. 16.
    Which organelle modifies and packages proteins?
    Show explanation
    The Golgi apparatus processes and packages proteins for secretion.
  17. 17.
    Osmosis is the movement of water molecules from a region of?
    Show explanation
    Osmosis is diffusion of water through a semi-permeable membrane from high to low concentration.
  18. 18.
    The site of respiration in the cell is the?
    Show explanation
    Mitochondria are responsible for aerobic respiration.
  19. 19.
    The nucleolus is responsible for the formation of?
    Show explanation
    The nucleolus produces ribosomes.
  20. 20.
    Diffusion is fastest in?
    Show explanation
    Particles in gases move freely, making diffusion fastest.
