I don't know science either btw .

This is hard. They all can be unicellular and can have chloroplast. I can't find the exact definition of their cell walls to determine if they are see through or not. sorry

Diatoms. They are encased in a silica cell wall. Euglenophytes don't have cell walls and dinoflagellates have thick, opaque walls.

Definitely diatoms.  They can look extremely cool.  They used to use the glass shells as an abrasive in tooth paste, but it was too abrasive.
