Yes.
yeswithout the cell the jellyfish is dead
One cell that a jellyfish has is nematocysts(stinging cells on tentacles).
No.
No, jellyfish do not have cell walls. They belong to a group of animals called cnidarians, which have cells surrounded by a cell membrane but no cell wall like plants do. Jellyfish have a simple body structure with a jelly-like substance called mesoglea between their outer and inner cell layers.

there is the stinger cell the outer cell and iner cells
jelly fish do not have a cell wall because they are not plants, only plant cells have cell walls.
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
A cell doesn't have a skeleton. Neither does a jellyfish though it's alive. (That last thing was just so you believed me.)
The jellyfish-like substance inside the cell but outside the nucleus is called cytoplasm. It is a gel-like fluid that contains various organelles, enzymes, and other substances necessary for cellular functions. The cytoplasm plays a crucial role in maintaining the cell's shape and facilitating the movement of materials within the cell.
The Nematocysts is a venomous cell that helps jellyfish catch their prey, and because it is filled with venomous materials, it insures that their food doesn't escape. It appears as if the nematocyst cell can sting itself and other jellyfishes. This cells also helps protect them from other sea predators.
