I don’t only see black dots, I see lithocysts. A lithocyst; they are calcium carbonate crystals that form on the cell walls. They definitely are not harmful to the plant, some theory’s say that they improve the plants ability to photosynthesis. They should come right off with a damp cloth or paper towel. If they don’t come off, try using vinegar or lemon juice to help break down the mineral build up. Hope this helps!

The black dots could be scorch marks from too much sun, or an underwatering/overwatering issue
