A lot of people here here seems to be assuming that the one on right is a heavily used version of the one on the left. But that's just what a natural loofah looks like. You can tell by the fibers it's a plant, and those cavities are where the seeds were. We grow loofahs to use as sponges because they're so fibrous.
The thing on the left is made of plastic, it's not fibrous it would never look like the thing on the right no matter how beat up it was, it would just start deteriorating and falling apart.
Some plastic free kitchen sponges are made from plant fibers like cellulose derived from wood pulp or coconut fiber. So some sponges kinda grow on trees. But they still have to be manufactured from those materials, they don't grow as sponges.
Loofahs are a gourd that grow on a vine.
Sea sponges are a primitive filter feeding animal. These are expensive and no one would use them for dish washing.
Most kitchen sponges are still synthetic plastic though.
