The organelle that serves as a storage area for starch in a plant cell is the amyloplast.

Here's why:

* Amyloplasts are specialized plastids (a type of organelle) that are responsible for storing starch.

* They are colorless and lack chlorophyll, unlike chloroplasts, which are responsible for photosynthesis.

* Amyloplasts are particularly abundant in storage tissues like roots, tubers, and seeds.
