The organelle responsible for holding chemicals needed for digestion in an animal cell is the lysosome.

Here's why:

* Lysosomes are membrane-bound organelles that contain powerful enzymes capable of breaking down various substances, including:

* Worn-out organelles

* Cellular debris

* Engulfed bacteria or viruses

* Food particles

These enzymes essentially perform the digestive process within the cell.
