Final answer:
The lysosome is an organelle that is associated with the terms contractile, digestive, storage, pigment, and poisonous due to its role in digestion and waste removal in the cell.
Step-by-step explanation:
When considering the terms contractile, digestive, storage, pigment, and poisonous in the context of cell organelles, the organelle that comes to mind is the lysosome. These organelles are known to contain digestive enzymes that break down macromolecules and have a role in autophagy, digesting cellular components, including damaged organelles and pathogens. Lysosomes are involved in a variety of cellular processes, including digestion and waste removal. Waste materials within a lysosome are excreted from the cell as the lysosome fuses with the cell membrane, a process known as exocytosis.
This is demonstrated by unicellular organisms like amoeba, which excrete waste by merging food vesicles containing digested food with lysosomes, leading to excretion through exocytosis. In multicellular organisms, lysosomes serve as the cell's waste disposal system, breaking down excess or worn-out organelles, destroying cells in the process of apoptosis, and defending against invading bacteria and viruses.
