There seems to be a misunderstanding in your question. Corpse flowers do not have specialized cells that produce strong doors. They are plants, and plants do not have doors.

Here's what's likely confusing you:

* Strong odor: Corpse flowers are known for their incredibly strong, foul odor that resembles rotting flesh. This odor is produced by specialized cells that release volatile compounds. The purpose of this odor is to attract pollinators, primarily flies and beetles, that are drawn to decaying meat.

* Large structure: The "corpse flower" actually refers to the giant, fleshy flower bud (inflorescence) of the plant, which can grow to be incredibly large, sometimes reaching over 10 feet tall. This structure is not a "door" in any sense, but it does serve a purpose in attracting pollinators.

In summary: Corpse flowers do not have cells that produce doors. They do, however, have specialized cells that produce strong odors to attract pollinators.
