Option 4 : Lysosomes

The correct answer is Lysosomes.

  • A lysosome is a membrane-bound cell organelle that contains digestive enzymes.
  • Lysosomes are involved with various cell processes.
  • They break down excess or worn-out cell parts.
  • Besides degradation of polymers, the lysosome is involved in other processes, including secretion, plasma membrane repair, apoptosis, cell signalling, and energy metabolism.
  • They may be used to destroy invading viruses and bacteria.
  • If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
  • The lysosomes are the cell’s “garbage disposal.
  • ” In-plant cells, the digestive processes take place in vacuoles.

  • Vacuoles:
    • A vacuole is a membrane-bound cell organelle.
    • In animal cells, vacuoles are generally small and help sequester waste products.
    • In-plant cells, vacuoles help maintain water balance.
    • Sometimes a single vacuole can take up most of the interior space of the plant cell.
  • Endoplasmic reticulum:
    • The endoplasmic reticulum is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding.
    • It is a type of organelle made up of two subunits – rough endoplasmic reticulum, and smooth endoplasmic reticulum.
  • Vesicles:
    • In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer.
    • Vesicles form naturally during the processes of secretion, uptake and transport of materials within the plasma membrane.
