No, bronchioles (except in the whale) do not contain cartilage.
The bronchioles in whales contain cartilage in order to prevent them from collapsing before other parts of the airways (and trapping gas in the alveoli). This helps prevent the bends - as nitrogen is removed from the alveoli before large pressures cause it to diffuse across the thin walls present there.

The function of cartilage in the lungs is?
Cartilage keeps bronchi open
Why are the cartilages rings incomplete?
This is very good question. Which haunted me for decades. If you have no cartilage, then your larynx and bronchi will collapse. If you have full cartilage ring, then your bronchi can not get constricted. Incomplete rings of cartilage has solved the problem. Your bronchi and trachea do not collapse and can constrict also.
Do bronchioles have cartilage rings?
No, cartilage is only contained up until the bronchi. The bronchioles and onward do not contain any cartilage rings, only smooth muscle.
How does the structure of the primary bronchi compare with that of the trachea?
Trachea contain cartilage rings, and is the long tube that goes to the lungs. The bronchi contain cartilage plates and are the branching tubes that go to the lungs.
Which has more cartilage the primary bronchi or the bronchioles?
primary
What is the diffirence of bronchi and bronchioles?
Very small bronchi are called as bronchioles. You have cartilage rings in case of the bronchi. Such rings are absent in case of the bronchiloles. You need such C shaped cartilage rings in case of bronchi, so that they should not get collapsed. The bronchioles are in periphery and they can not collapse because they are very small muscular tubes. C shaped cartilage saves lot of muscle mass of the bronchi to prevent them from collapsing.
What does the trachea and the bronchi contain that makes them stronger?
Rings of cartilage
Why does the bronchi have cartilage?
To keep them from collapsing due to negative pressure on an exhale.
Cartilage rings provide rigidity to keep the bronchi from collapsing?
True
Why bronchi have rings of cartilage?
Think about this one for a minute. Would it be a good idea for the windpipe to fold up like a garden hose every time you bend your head? What would happen if your air supply was cut off every few seconds? The cartilage keeps the trachea and bronchi open at all times.
What is the name of the cartilage structure the lies at the junction of the right and left primary bronchi?
the carina.
What Respiratory tubes are smaller connect the bronchi to the alveolar ducts and contain no cartilage?
bronchioles
